GP Extra 300SP unstable in roll
 

Evening guys,

I am looking for some input into what I feel is an issue. The aircraft is trimmed and cg is in the recommended range. When I fly the aircraft it does not really want to stay wings level. Its almost like its balancing on a ball always wanting to tip to one side. I make an input back to wings level and shortly thereafter, it falls off the other way. If I was building it I would say it needs a bit of dihedral. Obviously I can not put any in.

Does anyone have any recommendations? Reflex both ailerons?

Thanks,

The only thing I can think of that might do that might be an ail. servo not centering properly.

Check that the plane is balanced laterally. Also check that the aileron distance at the fuselage are equal, if .25 in down on one side, it should be .25 in up on the other.
