I have a Seagull Models P-51 ARF that has been converted to a P-51 Voodoo Reno Racer. It is a 60 size plane, 62" ws and am currently flying it on an OS 91 4 stroke, that was purchased with the plane. I bought the plane as you see it in the attached picture.
I have flown the plane several times now, and from the very first flight it has always had a tendency to roll left. I have shimmed the engine mount to give it more right thrust, but that tendency still remains.
Was just wondering if the wing may be warped. If so, would this be causing the problem? What could be done to correct it?
Thanks for the help,

Shimming the engine for thrust will not change the roll. Best advice is to go back to the basic's and start with the wing. Set the wing separately on a table blocked up and measure each wing end frt. and back to see if they are the same. If you know the centre line of the end ribs it would help. If there is a small twist this will give you unwanted roll and by looking at your ac it is plastic coated you and a buddy could twist in the oppoaite direction and reshrink. Takes a little practice.
If the wing is okay then reinstall, block up and check the ac from all angles. Wing trl.edge to rudder etc. Each side should be the same as the other. Also that everything is square, ie rudder to stab, wing to fuselage.
The last alternative is adjust your aileron's off centre. A little down on the left wing would stop it. Check it after a flight to see where you are at with your trims.
Hard to help with out seeing the ac but the problem is not uncommon and it is a matter of usually something out a bit.
Keep the shiny side up and the wheels down
