I've spent enough money for now, so OS is not an option. Between Magnum 46, SuperTigre .45 or .51.

One of the trainers at my club w/ a hangar full of planes said he LOVES his Super Tigre; I figured if he's training me I should be in good shape.

Nexstar manual has some weird configurations for servos and channels; it says you need a 6 channel radio (maybe since there aren't many 5's?) and have the option of using 1 or 2 servos for flaps.

So it sounds like there's no reason not to get a .51...
