3D, the single stir stick is "twitchier" My best one had a peice of shrink tube on the tail boom, that changed the cg just enough that the plane would go almost straight up out of a dive and do stall turns. Since the wing is only attached at the center, it allows more flex, and more "tricks" The double stir stick is much more stable and forgiving in flight. It will not turn as hard and fast, nor will it climb as fast as the double (especially the one with the tail boom tube shrink tubed). But it is much more predictable. I don't think one is better than the other, they both perform well, but fly different.

I think the most important mod is the turn w/o throttle mod. And if you think you are going to buy more planes, the three channels mod. If you are going to do both, do the three channels first then the turn w/o throttle.

The lighted plane has been retrofitted for the big charger, and the led's mounted differently( is that a real word?). Pic's later, Tim
