Dick:
You need to add downthrust.
Adding downthrust will cause the airplane to pitch down when power is on, so when power is on, you will need to add a bit of up trim to fly level. Keep adding downthrust little by little and retrimming as required until BEHOLD! you will reach a point where you can cut power and the plane will pitch down slightly into a gentle glide.
I would leave the CG at 33 percent, or even move it forward to 30 percent to improve the glide speed and pitch stability for landing.
I would leave the right thrust as is. [sm=sunsmiley.gif]
