GP Big Stick 60 Thrust angles
 

I bought a Great Planes Big Stick 60 and went to mount the engine (O.S. AX.75) and it “looks” like there is up/left thrust.
I emailed Great Planes and asked them what the correct engine thrust angles should be…

Dear Sir,

Thank you for your recent e-mail. The thrust angle on that airplane
should be:

3° Right
3° Down

Thanks,

Has anyone else had “funny” thrust angles on their Big Sticks?

Mine also "looks" like that. I "assume" it is an optical illusion.

Yes, I know I could measure it, but, why should I bother?

It flies great and tracks straight, and required very little trim to get straight and level hands-free flight.


Based on my one experience, I say put it together and fly it. If it flies right, no need to try to fix a nonexistent problem.

Yup the angles at the point where the engine mount affixes, are correct.

Just mount your engine square into the mount and it will be fine.

and then do a left roll and see what happens.
