http://www.helimax-rc.com/helis/novus/novus-125/index.html Novus 125s are hard to classify. They’re smaller than minis, so they can fly indoors. But they’re also larger than nanos and brushless-powered, for easy outdoor flying, too. Size puts them in a class by themselves, but so does performance. Both helis fly like much larger models, because they’re equipped like them. They offer the only torque tube-driven tail and heading-hold gyro in the sub-micro class. And a 2.4GHz radio with dual rates, so you can move up to the fixed-pitch FP — or the collective-pitch CP — with ease. Want more than a coaxial can offer? Then go to the head of the class: Novus 125s
