RE: Unexpected flight characteristics
Bad weather this weekend so no flying. But I did get the opportunity to scruitinise the plane more closely. The covering on the underside of the right aileron had delaminated over a length of about 20cm. This could pull back in flight causing a roll left requiring the right aileron trim that I had to input. Then a slow speeds the covering "popped" back into position causing the plane to roll right. Does that all sound plausible?
Anyway there was some oil residue on the seam (probably why it delaminated in the first place) so I opted to recover the entire wing, just got the trim to go then all done.
On the wheels the right wheel inside hub was broken. This wasn't affecting the rotation but I did allow for a greater freedom of movement on the axle so I replaced the wheels too.
I will post the final setup prior to flight and a flight report when the weather is better - Might get a chance during the week.
