Carbon Cub EX VS Mackey / Backcountry SQ2

There is already a thread with this exact topic, but it has been dead for some time and a lot has matured with both the SQ2 and the CC EX since that thread was started some years ago. Now that there are more of both out there I was wondering about the impressions/experiences people have had with each and how they stack up against each other.

I'm I the market for a kit sometime in the next year or two. I currently own a PA-18 with 160hp and most mods. I do a lot of off airport and I'm looking for something that can do just as rough but get in and out of shorter places or the same places with greater margins of safety.
 
Second. If not a comparison, at least first hand experience.
The SQ-2's showing up here look tough.
 
Excellent question.

The CC EX has matured and now has a large baggage option and also more fuel. Josh Peppard brought a new SQ12 to Valdez this year (SQ redesign of the PA12). The performance was amazing.

Like most airplane stuff it depends on your mission.

The CC will be a much easier build. It is a very well done kit with all components well packaged and labeled. It has an EXCELLENT builders manual. It is as close to cookie cutter assembly as you will find. Follow the instructions and you will have a wonderful flying Cub with excellent performance and resale value.
If you are in the lower 48 and just want to do a little solo fly-ins and camping, tough to beat. It will weigh 1000 pounds with extended baggage, extended fuel, and bushwheels. CC recommends 1885 as the GW, thus you would have 885 useful, though you can obviously set the GW where ever you are comfortable. Cost will be in the 130 to 140K range.

The SQ2 is strong heavy hauler Cub. You could probably get the empty weight down to 1150 or so and set the gross comfortably at 2300, giving you a useful of 1150 pounds. Build cost closer to 100K. CC has a hotrod 0-340 engine. SQ2 will have a hotrod 0-360 or one of the new lightweight Titan 409 engines. More power, more torque. Load it to the gills with a quartered moose, ton of salmon, camping gear, and it will haul it out. If your mission includes lots of heavy hauling, the SQ2 might be better. If your mission is light camping and exploring go with the CC. Define your mission carefully. Do you really only take one heavy hauling moose hunting trip a year? And the rest of your time is just playing and exploring? Build for the flying you will be doing 90% of the time.
The SQ2 will offer more flexibility to customize the airplane to your preferences. If you want heel brakes or toe brakes you can do that, the CC is a pretty fixed kit and tough to make large mods, thus toe brakes are your only option. Want overhead flaps in the SQ2.... can do. Want standard flap handle on the CC, no can do. You can only get it with the overhead flaps. Not that the CC kit is bad just that it would be tough to customize very much, where as the SQ2 is only limited by your imagination and skills. The SQ2 will be a tougher build. What are your skills and can you handle that?
CC is a reliable, large, well known company with an excellent reputation. You will get your kit on time and the quality will be excellent. Backcountry is a small company and in a little bit of a flux at the moment. Wayne Mackey is no longer there nor is Wayne Axelson. Is that good or bad? I don't know. I have no idea of the lead time to get a kit nor the quality. You would want to do some serious homework to assure yourself that you will be satisfied with your investment.

Define your mission realistically. Build for what you will do 90% of the time.

Hope this helps

Bill (my opinion only, take it with a salt lick)
 
Bill provides a good summary, with the most important takeaway being that these are two significantly different planes. I would add, though, that a stripped-down SQ can do pretty much everything a CC can do (watching someone like Goza or Mackey fly an SQ is truly a thing to behold), whereas the reverse isn't true--you won't ever be able to make the CC into the durable load hauler that the SQ is built to be. The SQ is slightly heavier by design because it's built like the proverbial brick outhouse for rugged backcountry use. The degree of customization available on the SQ, and the SLATS(!) are two other major selling points.

I think the CC is a beautiful bird, kind of a backcountry Ferrari (and I mean that as a sincere compliment). However, the long-term functionality and durability of the SQ, and the unbelievable safety cushion that slats provide, make it the clear winner for my particular tastes.

Full disclosure, I'm good friends with the guys at Backcountry, and I'm lucky enough to fly an SQ low and hard on a regular basis. I've never tried to build one, and I'm aware of the delay issues Backcountry struggled with in the past. I'm also aware of the impressive lengths the company has gone to in order to address those issues, both at the individual customer level and also structurally within the company itself. There have been some recent changes on the org chart, but those have all been for the good (and mostly by mutual agreement with the folks involved). They've always had a phenomenal product, and I think the company side of things is in a positive place and continuing to get even better. Just my two cents; take it for what it's worth.

PS--Backcountry is also still actively working on a new light sport design, which has the potential to be incredible (I've sat in it, and can't wait to see it fly). To their credit, however, they're taking the "prove it before you sell it" approach--meaning it will be done when it's done, rather than rushing it to market.
 
I think the break point will be if you believe in slats or not. The $$$ difference is made up in the fact that the Carbon Cub will sell for more at time of resale and may have a better following then an SQ2.

Me personally, I don't trust Back Country Cubs to be around to support their product in the future. So far they have been Daytona Cub, Smith Cub, Turbine Cubs of Wyoming, and now Back Country Cubs. Even their models keep changing from SQ2 to outlaw I, II, III and IV then back SQ2, SQ3 etc. They can't seem to figure out what to call themselves or their products. They seem confused at best with no solid direction and even all the key players have changed. Not a company I'd drop $100K with.

If I were looking at building up a Super Cub from a kit, it would either be from Cub Crafters or Dakota Cub. Both solid companies with consistent business histories.

One other point..... hate the looks of the SQ2 front end. I has got to be one of the most un-attractive cowls ever developed. I know it's functional, but it's ugly!

Just my opinion.

I think the break point will be if you believe in slats or not.

If you haven't had a chance to fly with slats, you should check them out. For me personally, I find them to be nothing short of amazing.

The $$$ difference is made up in the fact that the Carbon Cub will sell for more at time of resale and may have a better following then an SQ2.

I think you're right--CC may have a wider market share and better brand recognition at this point. That's part of what you're paying for in the higher price tag. However, I'm aware of a number of recent SQ resales where the owners definitely got their money back out of their planes. I also believe that the SQ will hold up better long-term in terms of durability, IMHO, and I think there are more and more happy SQ owners out there all the time. Both planes are very impressive when you see what they can really do.

Me personally, I don't trust Back Country Cubs to be around to support their product in the future. So far they have been Daytona Cub, Smith Cub, Turbine Cubs of Wyoming, and now Back Country Cubs.

I don't know anything about whether they were Daytona before Nick Smith had the company or not. What I do know is this--since it was acquired from Nick Smith in Canada, the company has had one primary owner. That primary owner remains the primary owner, and he is still very much involved. They were initially called Turbine Cubs because that owner was excited about the prospect of developing a small turbine motor and putting it on a Cub. He was very serious about it, and he put his money where his mouth was. When that didn't work out (they went so far as to hang one and flight test it but, unfortunately, the motor wasn't all it had been advertised to be by its developers), he renamed the company to focus on the company's primary purpose--building rugged backcountry airplanes.

Even their models keep changing from SQ2 to outlaw I, II, III and IV then back SQ2, SQ3 etc. They can't seem to figure out what to call themselves or their products. They seem confused at best with no solid direction and even all the key players have changed.

I don't know anything about the naming thing. As far as I know, the SQ designation came from Wayne Mackey's StolQuest design. Wayne is not officially with the company at this point but, from everything I know, they all remain on good terms (and they're still selling his design). However, saying "all the key players have changed" is just not true. The same guy that bought it from Nick Smith still owns and runs the company on a day-to-day basis, and he has all along. He was one of the guys sitting in the booth at OSH a couple weeks ago.

Not a company I'd drop $100K with.

I wouldn't tell anybody to drop $100K with an outfit they weren't comfortable with. I would, however, tell people to talk to others who have and find out what their experiences have been. By and large, I think most owners of these planes are very happy with them, but people should find out for themselves. I think the complaint used to be that they had a really good product, but poor customer service at times (with delay being the biggest complaint). Specific changes have been made to address those issues, and now I think their customer service is on par with the high quality of their product.

One other point..... hate the looks of the SQ2 front end. I has got to be one of the most un-attractive cowls ever developed. I know it's functional, but it's ugly!

Some like it, some don't. However, I can tell you that the visibility it allows is like not having an engine on the front at all. You can also get an old school PA-18 cowl on a Backcountry Cub, if you prefer form over function in the cowl department. As noted above, that's one of the cool things about the Backcountry kit--you can make it into whatever plane you want it to be.

I'm not a shill for Backcountry, and I'd be the first to admit that they've had their ups and downs in terms of getting sorted out on the customer service side. However, I know they've worked hard to address those issues and, personally, I really do think they build the best, most durable, most versatile Super Cub kits on the market. As I said though, don't take it from me--I'm a nobody--ask the guys who are flying them and see whether they are happy with their planes or not. If the product doesn't speak for itself, I wouldn't buy one either. As for myself, though, the SQ I fly regularly (owned by a friend of mine who has no connection to Backcountry whatsoever) has more than convinced me of the merits of this bird.

i built a pa-12 from a TCOW kit, the fuse was done by Jay at javeron who was at the time contracted to do all the welding. I know things have changed a little at BBC but i think it will all be for the better. My plane went together great Jay did a great job, Wayne built very nice wings and i didn't talk with Bruce much but everything was positive. I know in the past they have gone through some growing pains but this is common with alot of companies trying to take the next BIG step. Over all the build was fun and not to stressful, the plane is everything i want it to be, tough, gets off the ground quick and will carry a huge load. I use my plane for work and a CC to me seems more like an expensive toy( not saying i wouldn't love to have one) I to am not a huge fan of the bbc cowl but like stated before you don't have to use it. i would not hesitate to build a BBC,CC or a Javeron cub all are great just pic the one that fits your mission. good luck to them all
 
I just completed my SQ2, now referred to as the Backcountry Super Cub, in June. Flew it to Oshkosh. In looking at kits, I considered the Carbon Cub, the Dakota 18 and the SQ-2. I've built several metal kits but this was to be my first fabric plane.

I eliminated the Dakota 18 after parking next to, by random chance, the owner of Dakota Cub at Oshkosh a couple of years ago. I told him that I was interested in building a cub type kit. He didn't give me a business card; in fact he didn't give me the time of day. Now as Steve aptly points out in another post, maybe I should have given him a second chance, but when I didn't get any attention prior to writing the check from him, I figured my chances of getting attention afterwards would be nil.

The Carbon Cub, CC, is a great plane and it seems like they produce an outstanding kit. However, the CC seems like a "weekend jaunt" play type of plane for casual backcountry use. I looked very closely at the CC at Oshkosh. I found a number of small details that I thought were "interesting" in a show plane. Stuff such as stacks of washers on aileron & flap hinges, loose control stick assembly, et cetera. Certainly not show stoppers but nonetheless interesting.

I studied the SQ-2 and talked to the folks at the factory during a visit to Wyoming. I learned that the SQ-2 was being upgraded with quite a few notable improvements. One previous post in this thread takes the SQ-2 company to task for changing the name of the kit. If they make significant improvements why shouldn't they upgrade the kit name to reflect a new generation in the kits evolution? Geesh. Anyway, I ultimately chose to build the SQ-2 for two primary reasons: 1) The kit seems to be FAR more robust, stout and built to take a beating (from me) for years to some without undue fatigue issues; 2) The factory's continued commitment to upgrade their kit with notable improvements.

As also pointed out above, the same person has been the majority owner throughout the years. I can state through my experience that his integrity is fist-rate; his commitment to quality and making the kit "right" is outstanding. Case in point. As I started work on my kit I noticed a few issues with the welds on the throttle quadrant and the elevator trim bracket. The company owner loaded welding equipment and his best welder in his personal truck and drove 250 miles each way (!!) to personally fix my kit at my shop. If that doesn't illustrate the company and its owners commitment to the customer then nothing does.

There is a new shop manager at Backcountry Super Cubs. He has well over 5,000 hours in Super Cubs spread over almost 30 years in Alaska. He is an A&P and IA. I worked with him as I closed in on completing my kit with a number of minor issues. To say I was--and remain--impressed with his knowledge is an understatement. Now I'm working with him and the company on further improving the SQ-2 (now known as the Backcountry Super Cub) through the further improvement of their flaps--conducting airflow video tests with various add-on items such as wing trailing edge VG's and such. Again, the shop manager is totally dedicated to making their kits the absolute best.

Would I purchase and build another SQ-2/Cub from the company--absolutely! Will Backcountry Super Cubs be around next year and the year after that--I sure believe so...and if their current shop manager and long term company owner both have any influence on the marketplace I believe that their kits will be the new standard for robust, stout performance.

All that being said, there is no doubt that Carbon Cubs have a huge marketing budget and have their advertisements spread all over the literature (and web). One can't ignore the fact that CC is a very well funded company with a large marketing budget. They have a great product, but again as pointed out in previous posts, it is a different product for a different mission. You have to look at what you intend to do trip-wise and where you intend to visit (true backcountry or local grass field) to make a good decision for what kit you purchase.

I'd be happy to provide anyone details and pictures on my build and answer any and all questions regarding my experience with Backcountry Super Cubs. Thanks for this great website, outstanding forums and especially for the knowledgeable and friendly people who contribute to this site.
 
Tedwaltman1 what did yours weigh in at? What all mods engine prop choices did you go with? What kind of performance are you getting compared to a 18?
 
A couple of random thoughts...

Support? these are both experimental, and as airplanes go, both relatively easy builds... once it's complete just how much support do you really need? If it's a lot, to me personally, that would say something about weather I'd choose this aircraft for a bush beater... Piper Supercub's thrive just fine with Zero support from Piper ;-)

Are you the type of person, or do you engage in the type of flying that's likely to find you with a dinged wing or departed gear leg at some point in your flying career? and if so, are you then the type of person who will just call the insurance company and hand it over to them, or are you the type of person who might be inclined to do a ferry worthy field repair, and then fly it home for further correction. This is reasonably important, because a cub clone that is 90% interchangeable with a Piper is going to be a whole lot easier to repair than a cub clone that is completely incompatible with Piper parts.
A further consideration on this same tangent is what I call the 'Aviat' Factor... Not to start a Husky debate, but anyone who has experienced trying to get a gimpy Husky out of the field will tell you that simply acquiring the parts to cobble it back together can be a nightmare in time constraints. Bend a wing strut in a Husky, and it Might be on the shelf and available... Bend one in a Supercub and it will be red labeled to you the next day from any of several vendors... Any spare EX CC struts on the shelf in Yakima? I honestly don't know, but these type of questions would be at the top of the stack for me...

Are you a person who enjoys tinkering, or do you just want to build a 'known' project and go fly? As someone else pointed out, there is really, really little you can do to an EX CC to tailor it to your personality... That might be really good, or it might be really bad... Even if you're not a good tinkerer, the CC is going to go together just fine. But if you are a really good tinkerer, the other routes will provide you with less constraints.

As far as spending a $100k on any of these goes.... return on your investment in an EX is going to be hugely determined by the quality of your build. Barnstormers routinely has RV's that are just cr@p and their prices reflect that, conversely its not too uncommon to see RV's of the same model commanding top dollar, and getting it. Nearest I can tell most of the Cub Clones seem to tell the same story.

Incidentally, I was stuck on this same question a year or so ago. I think they both have ugly cowls, and really like most of what a stock supercub is. For me it made most sense to build more of a cub clone than either of these kits really offered yet still be able to take advantage of some of the freedoms the EX ticket offers.

Take care, Rob
 
Ted, I find your experience with Mark Erickson, owner of Dakota Cub to be unfortunate. I have known Mark for many years and have always found him passionate about his products be it a part or complete airplane. You might give him a second chance as mentioned in the other thread. His kit is made up of parts certified and tested to Part 23 standards and will interchange with most any PA18 out there. He holds multiple STCs, PMAs and the Type Certificate for the Super 18. Great guy to talk to and learn from.
I got a chance to look your SQ2 over at Oshkosh, wish I could have met you as well, looked like an awesome machine. I saw you had a pod and after some research I see you build them and was curious about features cost etc. http://www.eaerofab.com/ Anyway, hope to run into you somewhere and talk Cubs.
 
Regarding the cowl on the SQ-2, Backcountry Super Cubs is working on a new, more traditional, design. Nonetheless, that is the beauty of experimental--if you don't like it then get out your fiberglass supplies and make one you do like. But, if you just want a "put it together without thought kit," or certainly a kit without adding any personal touches, then maybe the CC kit is for you.

Off topic a bit, but mine weighs in at 1300, Engine is O-375 at 205 Hp from Aero Sport Power, Prop is constant speed Whirlwind Aviation model 210 out of Ohio. Power off stall is 28 to 30 (still experimenting with this area). Cruise with 35" Bushwheels is 75 to 85 mph at a reasonable power setting permitting 8.2 or so gph. Gross is 2200 lbs; 68 gallons fuel capacity with two 10g aux tanks. More questions: email me ted@eaerofab.com or tedwaltman@gmail.com

Thanks!
 
Indeed, perhaps the Dakota 18 and Mark are both great. But I had to make a decision at the time with the information I had. No offense to Mark. Everyone, as said, deserves a 2nd chance.

I do have a new company working on a 94" cargo pod, 200 lb+ capacity, with a 41" side door. I will have more information on the company website and here in a new thread in a few weeks. We have been working on a removable fuel pod for this cargo pod whereby one can have their cake and eat it too. All cargo, or cargo + fuel--all without having to swap pods or even drop the pod off of the airframe. While initially designed for the Backcountry line of experimental cubs, our pod molds have been created in a manner which permits us to tailor both width and bottom profile to fit other cubs as well. Stay tuned please...
 
my 12 is 1236, 0360 catto prop 31"BW 48gal tanks. no slats. if i wanted to lighten it up i could lose 30-35lbs pretty easy as it has a full alum int and full metal belly plus i insulated the boot cowl and fire wall
 
Not sure where I'd lighten mine up. Maybe take out the heated seat elements <grin--yes...for the wife>. Maybe use zip-ties rather than Adel clamps <g>. Take off the slats--no. Put on small tires (not going to happen). Take out the aux tanks--no. Sigh...
 
Sorry I wasn't trying to jump off topic. I'm a long ways off from building but I figured some real world numbers would help picking one kit from another. The company's give you there numbers but there trying to sell you there kit to. With real numbers with the mods on there gives me an idea of what I would be looking at when I build. Thanks for the information.

My SQ-2 weighs 1,203 lbs. 205+ hp O-375. 35" Bushwheels. Slats. Roll Spoilers. Double Slotted Fowler Flaps. Whirlwind Aviation 200A STOL constant speed propellor. 48 gal tanks.
 
Phil, is your cruise speed about the same as ted's? His seems slow to me. But, perhaps it is the big tires, since mine is 20 mph faster on floats at the same fuel flow? Or, can the slats be that draggy?

20.5/2320 gets me 90mph
22/2400 gets me 93mph

Flying locally I'm usually 19.5/2320 and going 87mph

Being a mostly lower 48 pilot I've never felt the need to exact calculate fuel burn, there is almost always a fuel stop close enough before I run out (or need to pee). For multi-day Idaho backcountry adventures I carry three 5 gallon fuel bags (plus a nozzle).
http://www.airframesalaska.com/product-p/fuelbag.htm
http://www.airframesalaska.com/product-p/fuelbagvalve.htm

I was first introduced to them bringing the SQ-2 down from Alaska.

For trips I plan for a 10 gph burn at 85mph. Always do better then that in both cases, but that gives me a decent safety margin with both time and fuel.

Changing from Skip Stewart's old Whirlwind prop (used while my new one was being built) to the Whirlwind STOL prop brought the cylinder head temps down 10 degrees. I just completed a Conditional Inspection and found one mag timed to 28 and the other to 30. I brought the 30 to 28 and the CHT's have dropped an additional 4 degrees. Before this she cruised in the low 400's so I didn't feel good leaning the mixture (and she hates LOP), now it's in the high 370's to low 380's so I will be able to lean her just a bit while staying under 400.

I've been told that 31's gain back a significant amount of speed, but I love the 35's and just am not in that big of a hurry when flying the SQ-2.

BTW, the air intake is a custom design, that is not how they look from the factory. Speaking of cowls, I love the look of the SQ-2's, but more importantly the visibility in flight - or rather its invisibility - a major bonus for off-airport ops. It did, however, take me a little time to get comfortable pinning her on wheel landings since I have no cowl to reference.

I've looked carefully at both the Carbon Cub and Back Country Cubs SQ kits. I figure cost to complete will be equal. Utility of the airplanes is excellent for both. One may carry more stuff. That isn't important to many users. One may land shorter in contest conditions. That isn't very important to most users. To me the primary question comes down to two factors. Do you want a lightweight plane with a conventional wing or a heavier plane with slats? The more important thing in todays market is do you want light sport or not? The Carbon Cub is the clear winner for E-LSA pilots. In the standard E-AB category both planes have merit, as do the more accurate Cub clones.
 
There are far more differences between the CC and the SQ-2 than simply slats. Fuselage tubing for one. Adjustable front seat; Fuselage side-load stiffener. Frankly, if you itemize the differences that are "under the covers" there is no comparison. Light sport might be a huge factor now, but if (when?) the FAA wakes up and changes the medical rules that will have a huge affect on the LSA market.
 
I just returned from a hunt above the brooks range. I have a nice 160hp working cub and was able to fly in our camp and four people with just 5 loads. I was in the same camp several years ago with a pacer, could have done the same job as my cub with only one or two more loads. If you fly light and are a pilot that can hit your spot every time and roll it on with ease. Than a lighter plane is fine. If you are like me and don't always make the soft landing. You may need a plane that takes abuse. Add pulling gear in and out of the plane 4-8 times a day it is nice to have a big tough plane. You already have the best of all worlds!!!

The margin of safety is in the stick controller not the plane.

I think the break point will be if you believe in slats or not. The $$$ difference is made up in the fact that the Carbon Cub will sell for more at time of resale and may have a better following then an SQ2.

Me personally, I don't trust Back Country Cubs to be around to support their product in the future. So far they have been Daytona Cub, Smith Cub, Turbine Cubs of Wyoming, and now Back Country Cubs. Even their models keep changing from SQ2 to outlaw I, II, III and IV then back SQ2, SQ3 etc. They can't seem to figure out what to call themselves or their products. They seem confused at best with no solid direction and even all the key players have changed. Not a company I'd drop $100K with.

If I were looking at building up a Super Cub from a kit, it would either be from Cub Crafters or Dakota Cub. Both solid companies with consistent business histories.

One other point..... hate the looks of the SQ2 front end. I has got to be one of the most un-attractive cowls ever developed. I know it's functional, but it's ugly!

Just my opinion.

Crash

Very well summed up in my opinion.After my expensive disagreement with BCC I was supported very admirably by Jay at Javron cubs.I cannot say enough for Jay or his products.His new light wings are much lighter than BCC's wings were.The support and encouragement endless.Put any idea in Jays head and he will work on it.Have a chat to him,you will not be disappointed!
 
There is already a thread with this exact topic, but it has been dead for some time and a lot has matured with both the SQ2 and the CC EX since that thread was started some years ago. Now that there are more of both out there I was wondering about the impressions/experiences people have had with each and how they stack up against each other.

I'm I the market for a kit sometime in the next year or two. I currently own a PA-18 with 160hp and most mods. I do a lot of off airport and I'm looking for something that can do just as rough but get in and out of shorter places or the same places with greater margins of safety.

I was not going to make a post on this thread but after re-reading it decided to.

The number one thing I (as well as Wayne Mackey) tell people and stress is SAFETY. The SQ2 is simply one of the safest high performance experimental bush cub type aircraft on the market today. There has been NO lose of life to date in one of these aircraft. How about the CARBON CUB???? Lose of life....YES.

As for as performance goes, there have been SQ aircraft built by some the most respected builders out there and also as a first build by the most novice builder. So yes there can be a varied degree of flat out performance.

As for as Backcountry Suoercubs, there has been major changes in the organization this year. They have better product, service, and support. You are welcome to stop by Douglas, Wyoming, anytime.

At the end of the day, get the airplane that will accomplish your personal needs the best.

One last point, like MikeO has said before "just ask Crash, he knows".

Cheers............

The Cub wing has been mighty popular for the past 75 years. To imply that it's dangerous is a bit of a stretch.
 
The Cub wing has been mighty popular for the past 75 years. To imply that it's dangerous is a bit of a stretch.

Any wing can be dangerous, depending on how it's used. I think it would be a bit of a stretch to imply that a safe wing can't be made safer (not that this is what you were saying but, frankly, I don't think that was what 5 Rivers was saying either).

They've been saying for 75 years that the Cub is a plane that can just barely kill a guy. Based on my experience (which pales in comparison to people like Goza and Mackey), I firmly believe Wayne's slats help make that "just barely" a little smaller. Others' mileage may vary, but I know some good pilots who will swear that slats made the critical difference for them when the chips were down.
 
If I may, a slightly different perspective on "safe" wings. I think it's how close to the edge of the wing's capability that one flies, that determines safety, assuming the wing is predictable. I have the cuffed wing with VG's, and it is much more tolerant of sloppiness on my part than the stock wing is. If I fly it about the same as I would a stock wing, it definitely offers increased safety. But if I fly it on the edge of its performance envelope I'm asking for trouble - it may not stall abruptly, but it sure can run out of lift. In other words, both wings are safe, but one has a broader range of safe conditions.

Kinda like as a "kid" when I bought my first 4WD pickup - promptly got it stuck, but in much softer terrain than the old 2WD would even have gotten close to.:oops:
 
Serious questions.
1) has anyone out there fitted slats to a Carbon Cub wing?
2) has anyone out there fitted Keller flaps to a Carbon Cub wing?

I know these applications aren't supported but this IS the experimental category.
