From reading JimC's posts it seems like the major difference is in the RPM at which maximum HP is achieved. The C90 for example made 90hp at 2450 whereas the O-200 makes 95 at 2700. Same displacement...

IIRC per JimC the C90 cylinders are different as the rockers travel further and open the valves more. The C90 cam is very aggressive with large lift and timing which is how it makes so much torque. ...
You're having everything overhauled but don't want to spring for a stroker crank for a big money overhaul. I'd reconsider how you're allocating your overhaul money.
The STC includes a bunch of drawings to either fabricate your own new parts (such as the fuselage and engine mount) or have someone build them for you. Airframes holds a PMA directed towards the...
Yes, the Sullivan STC calls for fabricating a number of new parts including a dynafocal engine mount.
It uses a wider engine mount as the fuselage is wider in the front where the mount attaches.
The wood spars can last 80 years and longer no problem as long as they stay sealed with varnish. The paint/fabric is the problem. Would likely require a recover. Hard pass.
Numbers matching A65 to...
65hp is going to definitely limit the cost as most of them have been upgraded to the 85 or 90 horse engines. The market is all over the place on J3's depending on condition but I'd say 30k plus or...
He will truly be missed. He came into Reeves last year just to chat and tell flying stories. Had no idea who he was until he recognized my plane and we exchanged handles on here. Just a super nice...
Both good planes with the "best" engine. The -8 has no provisions for adding an electric starter or generator so you're married to hand propping which isn't a bad thing at all on small engines. Saves...
Please don't do any of those mods except perhaps the tailwheel. -18 tail feathers and gear are just useless weight on a PA-11. You can go a surprising number of places on 29" Airstreaks with...
I've never been unhappy with my C85. More power would be nice but it's better to be light and know how to fly your plane. The C85 is a great little motor too.
The performance difference is going to depend on the propeller and engine condition but all things being equal the C90 should perform better than the C85. IMO the C-90 is the sweetheart out of the...
The ABI-1010 STC says "29x11-10 4 ply or 850x10 6 ply". The smooth tread 29x11-10 4 ply aero classic tires fall under that and are approved. They do not however weigh much different so it will still...
Unless it's a 180/185 jump up to 31's and skip the 29's. Not a noticeable amount more drag and a much softer/more compliant tire. Weight difference is also negligible.
Great idea Oliver, we can sell those too!
Keep in mind you will have to get custom pod straps or put extensions on regular straps you may get with a pod. Anywhere in the 38.5-40" range is fine. It should be just ahead of the cluster as you...
There's a wide variance in wood grades and weights. If, for example, you are very selective about your woods and get lightweight Okoume mahogany marine plywood in 3/16" thickness it's very close to...
Just measured one here in the shop. The door is 27" long, 12.5" tall in the front and 10.5" tall in the rear.
I'm not sure what experts these are but I would vigorously disagree. Perhaps it's the better technique for a smooth grass runway but for my purposes the tail is the first thing to leave the ground...
The beach had lots of sticky mud with small rocks getting thrown into the bottom of the wing and back of the prop from the bushwheels. The theory from my brother and his mechanic is some of the small...
I've said this before and got flamed but that heat shroud design is problematic. My brother managed to get dirt in the end of the heat shroud and it destroyed a cylinder last year.
Correct, the fittings were changed shortly after we spoke in 2021 to move that cut back further to allow for variance in wing fittings. Haven't heard from anyone with the same issue since.
On...
The guys from Vans say it's going to be a 2 seater with a 4 place projected later on down the line if this is successful. The model shown at Oshokosh was very much an unfinished prototype and it's...
An engine out and coming up short is a risk regardless of how fast or slow you're going. Whether fast or slow you're only going to travel a certain distance and if that distance is one foot further...
