Light-Sport Aircraft Yahoo group Re: Spoilers versus ailerons

your post made me think of up-only ailerons that are another alternative with less complicated controls and no adverse yaw . just activate the aileron on the side of the turn and it pulls the wing back and down. one pull cable to each aileron. i had a weedhopper with no roll controls and a terratorn ta with spoilers in the past.
