Powered and unpowered flight

The model has been already fine tuned for the unpowered phase of flight. When you turn on the motor your model might tend to pitch nose up when full throttle is applied. You cannot completely trim out this tendency with any motor powered glider – just be aware of this characteristic when flying your model. In practise you might have to make slight elevator corrections to maintain a gentle, but positive climb. In some cases there might be a strong trim change, and the only cure for this is to modify the thrust line of the motor. In order to reduce the nose up pitching you have to increase the down thrust of the motor (by using card or scrap ply packing pieces). The opposite problem is quite rare, but it is possible that a model correctly set up for the glide requires a lot of up elevator to maintain a climb when power is applied. The cure: decrease the down thrust of the motor.
