Okay, thanks!
No, thats not it. I am trying to get pictures now. These are brand new. Robbie Grove built three sets. He has not advertised them yet. He may try for an STC. I'll post pictures as soon as I get em.

Very Blessed.
Aww, you guys are so generousUnfortunately the trial list is about a mile long
I have to say, I got to sit in on the whole product development process and it was pretty exciting for everyone at Wipaire. It was taken as a real opportunity to try some new things at the risk of failure and not having the floats ready in time. The engineering and production team also elected to take the route of building light and adding weight later if structural testing and the seat-of-the-pants testing (does it feel sturdy enough, etc) reveal that something is lacking. It is very easy to add structure "just in case" and overbuild, so this was a very cool exercise to witness and I am excited to see it continue to develop.

I have stayed out of the conversation for long enough...... Here is one of my certified STC/PMA brake cylinders that I have been producing for the last several years...... At $400.00 each by the way..... Looks a lot like the Grove cylinders.... wonder where he got the idea..???

The Grove 95-1 and-2 are not certified, and no plans to do so. Didn't ask about the 680.
Those would look nice with my gascolator. 'Specially if they were gold.
I saw that some folks are trying to bring back the Franklin engine. A great engine at about the same weight as an 0-360 but producing 220Hp.
It has a lot of great features and if they can get support it could be another option for RV's, Supercubs, Bearhawks, etc. The smaller 125Hp might be a player for light sport aircraft.

Pat - thanks for the writeup! Looks like it might be worth the investment.

I was wrong. Your link was correct to the new Grove brakes. Here is another link with more info.

Yes sir!Hope some video comes out soon as I have heard from a reliable source that they are 'friggin' impressive.'

I got a good look at Mark's spoilers. Cool. Want to fly it now. He was a ways away and took us a while to find him but as usual it was worth the hike.

I've wondered for years why someone didn't put spoilers on a Cub.....Makes sense to me. Let's hear prep.MTV
I have spoilers on my 2 plus 2, and the only thing I use them for is taxing in a stiff wind, or when tied down in the wind. Somebody explain how to use them in a cub with flaps.

Need more INFORMATION.Yes sir!
Pull them and it spoil's the air flow over the wing...

Well kiss shock cooling goodbye I bet that thing falls out of the sky like a rock when you deploy them at altitude.
I was told they really shine when you pull full flaps and deploy the spoilers. Allows you to head downhill at a freakish angle, and then you can retract them and flare to land. The slot keeps air moving over the ailerons at slow speeds when you flatten the descent out, so they are supposed to work very well together. But, this is all secondhand so I may be completely wrong. I look forward to hearing more from the folks out at DCA.

That looks a lot like the North River design.

Do the spoilers work with aileron?
One of the nice things about the helio is that the spoiler comes up to drop the wing, which reduces the need for lift on the other side, which leads to less adverse yaw...
At some point, coming down is not the problem!
I don't know where you've been me lad, but I see you won first Prize!
It is a lot more maintenance friendly than the North River booster. It is a vented cylinder so temperature and altitude to do have an effect on braking like the NR plus you have a reservoir. I think aviation has always been an industry where someone takes another's idea and improves on it dating back to the Wright brothers.

how long till they are available for experimentals.
Ve haff veys of making you talk.
My point exactly. Brian being sarcastic about where they got their idea for the master cylinder was a little bit hypocritical.

I only have just secondhand information . . . the guys at DCA will be of more help but if I hear more I will let you guys know! Hopefully some got a chance to speak with Mark as it is his brainchild and he can speak to it better than anyone.how long till they are available for experimentals.

Yes I was being sarcastic... That was the point, and me being a bit of a joker... I keep forgetting that internet forums cant distinguish between joking around and being serious...
I actually like Grove products.... One of these days, if I can ever get the PA-28 taildragger approved, I will be hopefully buying a lot more gear legs from him..
I actually got the idea for the brakes from the internal workings of the Cleveland toe brake, just bigger and made for the Scott frame.
Brian.
The North River was designed the way it was in order to make something that worked better than the Scott diaphragm on disc brakes with large bush tires. The intent was to make something that was easy and inexpensive to manufacture so as to be able to get it approved by the FAA without much difficulty. The result was a tremendous improvement for those applicable airplanes and saved a lot of planes from being wrecked. Nothing else was available at the time, 1984, that was as good for the small amount of $$$$. All of the subsequent iterations are improvements on the NR idea for more $$$. Just for your information there are a couple of ways to install the NR boosters which eliminate the hassle, described above, of the sealed system. They just haven't been FAA approved in order to keep the cost down.

Pete, I don't ever mean to knock the North River brakes. They work very well. It is interesting to me to see someone improve on a design and make it better over the years. This is a perfect example with the original Scott brake with a diaphram, the North River piston and now the Dakota Cub and Steve's Brake. This is what makes Super Cubs so great, people will spend the time and money to improve on them and hopefully get a return on their investment.

Mark told me he was dumping about 1/3 of the lift with his spoilers. Pull them and she comes down, dump, flare and then pull them again to stay stuck. He is using an electric linear actuater to move them. More testing will tell more. Can't wait to fly them myself.

Steve, I did not take your comment as a knock. At the time there was nothing else available and the shortcomings were known. I am pleased that my idea was improved upon. In the meantime there are several thousand NR boosters in service which can be improved upon without replacing them with more expensive units.
This picture shows one of those methods.

I saw one with a Prince Albert can fastened to the interior panel and a tube and shut-off valve to the booster. Simple and cheap.

So, I'm curious... A switch to actuate, or a handle? Can have half spoilers, or 3/4 or full? Sounds cool. Could be number one new mod. Why hasn't this been done before on cubs? The old L-2 tcart had spoilers, but you were never going to get out of a spot you'd need spoilers to get in. Cubs should be more balanced in that respect.

Mark told me they cycled full up and full down in one second each way. Most likely it's all or none. jg

It was a switch. It was on the stick grip but had a bad switch and was using one on the panel for the time being.

Old friend of ours had a set of STC'd spoilers on his Cardinal RG..... They operated by twisting the throttle..... Worked real slick, you could land on the numbers every time.... I can only imagine how short you could get a cub in with a set...
Brian.
They almost have to have a switch on the throttle or stick for landing, other wise they are almost useless unless you have 3 hands. ( Like mine )
Things found at Oshkosh, Wed afternoon I saw Ed Doyle in the flymart hauling a stuffed pigs head around and I yelled over to him that he should put it in Tooltimes tent, but then I saw it hanging on a post at the pig roast. It looked like it would have made a dandy girlfriend for Tim

I was carrying on a conversation with my Dad on Wed. morning when I got interrupted by a loud prop and I cursed those AT6 but when I turned around I saw it was Ed and Charlotte climbing out.
