Thanks rc. I bought a trainer for my sisters boys at Christmas and noticed the elevator was to have a half inch travel up and down. A friend got me started in building coroplast planes and just after lifting off at times the planes want to climb way to much. I checked my elevator and there is close to an inch of travel both ways. I adjusted the travel tonight down to a half inch. Im hopeing this makes for a tamer take off. A friend that is helping me to learn to fly said this last coro plane I built seemed elevator senseative at take off. Other then that it flys well. Im hopeing the half inch travel helps on take off.
