Your English is fine!

A UCD 60 with a pumped .91 would be a fine combo, you won't have the problems related to the high tank position with a pumped motor.

If you set the airplane up as per the manual and use the low rates you should have no trouble AT ALL flying it initially. This airplane really does give the best of both worlds and can literally "fly like a trianer" when set up on the mild side. In my opinion the CG range that is shown in the instructions is very conservative and if you stay within those limits the plane is almost to stable for most of us that do 3D, but it makes the plane very easy to fly.

Get one, you'll be glad you did.
