RE: Probllem with airplane roling without cause
I had a Hobbico cub that rolled to the left when I gave up elevator, and it turned out to be that the wire joiner for the elevator haves came unglued. On the ground it looked fine but in the air only the left half was going up and causing it to roll. So I would recomend checking to see if both halves of the elevator move the same. Sorry, I posted before I read the second page.
