Nope.

Weather or not the fox 40 hovers your plane completely depends on the final weight. The newer "fat free" taco designs from Swany are much lighter. The Taco is fully 3D capable but a tad twitchy for the uninitiated.... if you want a good 3D trainer then the Burrito from Swany is the best. They're just as cheap as scratch building, too. But I'm a big believer in using what you've got...so see how your setup works. IF you need to step up the power..the TT 46 Pro is a good, cheap, reliable engine.
