I have this engine in an ESM Corsair and a Greatplanes Waco. Wingspan about 72-74 inches. I know of one in an ESM Val and a Storch. Probably ideal for 70-76 inch wingspan 16-20 lb models. OT is a little big for the Waco, but not indecently so.
Other contributors might have other ideas.

I also have my 38 in the Waco and it fit great and hauls the plane around quite well. I have always wanted a Storch so I will see if I can find one. Thanks!

Shame about the Storch! I won't be buying another ESM Corsair either! The flaps are an absolute PITA and the ARF was missing some hardware.
It's a pity about ESM. Can't buy in my part of the world, freight from USA is stupidly expensive and the kit is missing bits!!!
No, I won't go down that road again!!

What about "Blackhorse " models? I can't get them either, but maybe you can. They look quite good.

No . Not an ESM I think. I believe Tyor has a 38 in a Blackhorse Storch. I could be wrong, there is video of his model flying if you search this thread.

Watched the video! What a nice plane. I really want one now. I will look for BH version. I think a place called Hobby People in California carries BH models. Thanks for finding that post!

P.S. I have a friend at the field that has the giant esm corsair and had the same issues. He also thought it was a bit heavy, but has a DA60 in it and it flys well.

About to complete the tank installation in my Tiger Moth which will have the GF-38 inverted. Can anyone please advise the optimum height in relation to say the crank center line.

It doesn't matter so much with "gas" engines since the carburetors have diaphragm pumps & regulators.

Thanks, was a bit worried that the carb may flood as the tank center line is currently above the height of the fuel inlet.

So..... after a 6 month wait whilst I tracked down a replacement wing ( had to buy a complete arf kit ) for my ESM Corsair I finally brought her back to the field.
New spark plug, started second spin of the starter, minor tune for the hot conditions of the day and away we go!
The GF 38 ran really well!!

How has these motors been holding up? I thinking of getting another one for a Great Planes Avistar GP/EP
My old one ran very reliable but shacked a lot. Are you guys breaking any parts like mount or manifolds have the airframes holding up like the fire wall and stuff. Just if they could make a cheap twin.

I have mountet one of my 38cc in a pilot-rc 25% sbach. Interesting to try a 4-stroke in that kind of plane. checked cg without the ignition module end the ignition battery in the plane. and it was a little tail heavy, so putting the module and battery up in front will fix that

Looks good Tyor!
I had an interesting morning with my corsair 38 yesterday. Was tuning when the engine began to misfire. It then stopped and when I turned it over by hand there was almost no compression!
So I thought I'd check the valve rockers, the whole rocker arm rod was loose!! The hex screw that holds it had vibrated loose!!
Tightened up and re-checked clearances. Ran it. Runs good!!
Phew!!!!

My engine was acquired from a club member who had it mounted in this type of model. It flew OK, but rattled and shook plenty and we reckoned the chaff-cutter sound was all wrong for this plane.

I intend to mount it in my 90" Eindecker which is currently a little underpowered with an old Zenoah G-26. One more project on the ten-year plan .....

I think the engine wil be ok in the eindecker I have only 4 stroke engines in my planes now and no more glow engines so if the sbach dont work with the ngh I maybe try a saito gas. I have 2 saito radial engines. one fg19 and one fg84. Both run perfect. here are a video of the fg19 in a hangar9 sopwith camel.

Default Soft Mount

I've decided to try installing this engine using the DUBRO 1.20 soft mount. I needed to modify one of the mount rails by filing it at an angle to clear the carb. I also filed down some of the choke control arm material to also give me some clearance. I hope this works!
