Hi everyone I a few days back I took off my stick type plane which I built long ago.
When it was in the air I tried to turn it towards right side but it is not turning. (no problem with left turn).Its actually 3 ch plane.The rudder seems ok.What may be the problem

Check the wing loading.. Left side wing may be heavier than right side.

Ok sir I will check that.

Thanks sir.Figured it out.Right side of the wing is around 5 grams heavier than left side, and right side of the wing is not lying flat on the ground.
