Hello,

I just purchased a Gemini Bi-Plane by Multiplex. The question is when I take off and get a few feet off the ground the airplane tends to roll to the left. I have to apply a little right aileron. Once airborn it flies straight. I have about 3 degrees of right thrust set up just like to book calls out for. Can someone explain why this happens?

Thanks for the help

If it was rolling left I would say it is torque. Might want to re-check your thrust angle on the motor mount.

Should I increase the right thrust to 4 degrees. That is the max they call out for in their manual.

If that's the max then I would say give it a shot. It wouldn't hurt to try it out for one flight and see if that makes a difference.
