I built a Smith miniplane k&b 61 with header and tuned pipe, maiden flight yesterday almost crashed it upon takeoff had to apply full right aileron and hold plane still banking so quickly applied full right rudder and finally with full right aileron and rudder was able to get up and away where I had time to trim full right, it was somewhat a handfull to say the least, I brought it in and safely landed, I'm looking at why the ailerons needed full right trim to be off so far for the plane to fly straight, could lateral balance have that much effect? She is left heavy due to pipe and header but didn't think it would be that much of an issue? Never had a plane trim that far off, all the control surfaces were dead center to start, now ailerons are really far off center to the right,
