Motor thrust line for high wing pusher

[Buzz_Man]

I added two degres of motor tilt as shown in the image below (two actual degrees were added - the amount of motor tilt in the image below is exaggerated).

What do I need to do to fix this problem?

Thanks,

Buzz

What is "the problem" that needs fixing?

The only way to determine the "correct" angle is to fly it and make adjustments. It will vary by power system, prop, speed flown, etc.

I was told in another forum that the angle of thrust I added was probably backwards.

Buzz,

It looks like that may be the case. The tip of the spinner should be higher than the motor. Then like the man says above you just have to fly it.

Check out some of Sparky Pauls posts.

The motor on my Wingo is angled "down" like your diagram shows, and it works well as it helps to prevents pitch up under heavy power. When I had it more 'level' the model would nose-up under power.

Thanks Andy . . . um . . . there's a terribly similar resemblance between your avatar & my mother in law . . .

[Beginner!?]

but what's about right or leftward motor mount for these kind of PUSHER planes?

thanks

[Buzz_Man]

I don't care much about right or left thrust - at this point I'm just hoping for a miracle - more on this plane later . . . I forgot to bring the control rods this morning and we're out for Spring Break next week . . . I ended up going across the hall and borrowing some welding wire for the pushrods . . . the whole project is like that . . . boo boo here, boo boo there . . . boo boo's everywhere . . . :rolleyes:

The motor as drawn may be correct, for that great distance between the wing and the tail.
I'd start with zero though.
