Plane is set up 0 on stab 0 on motor wing +2 built in as per plan. Plane is very pitchy from low to high motor power. Balanced right on. Any one had the same thing happening to thiers. Also using 8-4 apc and 8-3.8 sf props with 6 cell pack, does any one have a better prop set up I'm getting about 4-5 minutes full power which is about right. Motor is Kyosho hop up car motor bb. Could adding up or down trim to motor take the pitch changing out. Plane takes off in about 20 feet and flys great but have to keep trimming every time power goes from low to high or back Thanks

if the nose it pitching up at full power, put more down thrust in the motor. I would start by putting a shim under the back of the wing a take a little of the positive incidence out of it.
