If you're planning on doing a low inverted pass, you might want to go ahead and order two of them I was flying about 3/4 throttle when I inverted mine. When I gave it some down elevator, I'm guessing it stalled, and started it's inverted fall. I never tried it at full throttle....might work...might not. Also, I've got the flaperonsmixed in with the elevator. When I gave it down elevator, the flaperons also responded, in the opposite direction. It is much more responsive to pitch inputs this way. Without the elevator/flaperon mix, it may fly just fine inverted. I did the elevator/flaperon mix becauseitjust doesn't like to flare very well (when landing) with elevator alone.With the mix, it flares very nicely.
