Use Low rates on the elevator when flying, or you may find it snapping over if you pull up too quick. I had mine loop right into the ground because of it. At low rates its just the right amount of elevator. I use full rate at takeoff, and as soon as it leaves the ground I flip to low while also flipping the gear. Mine with a Saito 125 flies nice, its getting the 125 started that keeps it from flying.
