Unfortunately we didn't get much time to prep for this one. Due to the weather many of the competitors showed up literally minutes before the contest so we really didn't know what we were working with. Dan Reynolds had to drop out of the competition due to his brakes failing last minute. I...

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 but very different cams and valve lifts. The C85 stroker is supposed to do 93hp at 2575...

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. O-200 crank, C85 pistons, electronic ignition, a Marvel carb, and advanced timing are the best...

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 Sullivan STC to manufacture these parts.

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 airframe? Might be of value to a collector but for flying I'd go with the C85 and not be concerned...

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 minus 5k would be a good middle of the road price.

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 guy and good to talk to.

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 some weight out of the accessory case. For me it would be the PA18-95 if the weight is...

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 everything else fairly stock. That being said, if the C90 one comes with Baumann 1500's thats worth it's...

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 small Continental lineup. Makes nearly as much power as an O-200 but at a much lower RPM. Lots of...

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 be fairly heavy.

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 did there.

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 as light as carbon floor boards. On the other hand if you use heavy 1/4" A/C fir ply from a...

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.
