Anyone out there with this combo have to add more right thrust?When I pull vertical and give it full power,I have to hold almost full right rudder to keep it from yawing left.I'm hoping it's just a thrust issue,but I'm also concerned it could be due to my elevator balance tabs having some twist in them and dont know how this would affect the airplane while in the vertical.Straight and level it's fine.

KAJ,

Which Hanger 9 plane is it?

whoops,that would help huh.It's the 1.20 cap.

Yes, mine needed about 2* more right thrust with a Moki 1.20 in it. The best way to tell if it's a thrust issue is to pull exactly vertical and let go of the sticks...see which way it goes...as the airplane slows down, the wing stops flying and the motor takes over, giving you a yaw or pitch. Make sure your rudder trim is centered as well. Oh yeah, mine also needed about 2* of up thrust as well......havent found an ARF yet that was set correctly. One last thing...make sure you stay with the same prop once you get it dialed in, as it will change with different props.......
