Thanks a ton for the advice. I will definitely rebalance the plane to put the CG where it belongs! If only I could do it sooner!!! I won't be able to fly for at least two weeks... but when I do, I'll make sure to take all of the advice in mind.

CafeenMan, that elevator comment rings so true!!! Why didn't I think of that? (there must be a acronym for that... WDITOT?)

Michpitssman, I definitely don't blame the plane completely... But when I first installed my FZ63, which is only marginally heavier than the 46FX, I needed around an ounce of lead on the engine mount to balance the plane. At that time the battery pack was forward the CG next to the tank. So I naturally assumed that the plane could take on a heavier engine... but this China made engine is very crap (I know that's poor grammer but hey, I like the way it sounds... better than just "crap" or "really a peice of carp"). I am turning only a 11 x 7 prop and only at about 10-11k rpm. And I have to open the needle 3/4 turn to get it pass the vertical test. I refuse to go to a 11 x 6 because that was what I was on with my 46FX that has since seen the last of its days when my pattern plane smashed into the ground, disentegrating the front half of the fuselage.

Anyway, I agree with you... overpowering does not equal overperforming...
