ok now I get it! I'm going to leave my trex 450 in a 3d setup.

I have another question though for those of you 450 owners using the new 3700 motor or anyone with experience with it: at what power setting on the throttle curve should be your hovering throttle? mine is set up so that it hovers at 80% power and 5 1/2 - 6 degrees of pitch. the manual says it should hover with 65%, but when hovering at this throttle the moto get hotter than when it is at 80, so what is the best throttle setting for hovering in normal mode in terms of efficiency?
