Pretty snap rolls right; ugly left

[HobbyJumper]

My Fun Cub rolls smartly along its longitudinal axis when the aileron stick is yanked right, but the plane falls away in an ugly corkscrew if the stick is yanked left. Just curious. I gather this has to do with propeller rotation, correct?

Also, I think I just described an aileron roll.

Yep, that's just a 'roll', a 'snap roll' is when you flick the plane round by applying lots of elevator and stalling a wing, i'm not sure if this is even possible on a Cub?.

Most planes actually roll ever so slightly faster to the left because motor torque is trying to turn them that way anyway. Are you sure that when you move the stick hard left that you are not inadvertently adding some elevator? Also check that ailerons have full and equal movement in both directions.

Try getting up to speed (did I just use the word speed in relation to a Fun Cub? ), chop the throttle and see if it's the same either way.

JPF - can't speak to a Fun Cub, but I can assure you that a 1/4 scale Super Cub will indeed Snap Roll

Cool.. I'd like to see that

Sort of a snap roll-wallow

Won't happen with that PA-18 again, it had a bad case of terrain non-avoidance
