Mike, Yeah I got a few different props to experiment with-- I think that my dad picked up a APC 9x4E and an 8x4E just to experiment.

Edwin, I reinforced the tail with some CF rod as soon as I possibly could- The tail section of the fuse twists around like a wet noodle if you dont do any reinforcing. The roll rate acually sped up. The sad thing about the tensor is that it rolls pretty slowly.
I about ready to ditch my tensor and move on to that new Yak 54f from E-flight. My dad flys one of these and this plane flies REALLY good. He calls the tensor a box kite with a motor
