The Mountain Models Clipped Wing Cub was CAD designed to be a lightweight, super easy to fly, laser-cut, scale electric parkflyer.
Interlocking laser-cut balsa and plywood parts make assembling the models as easy and as fast as possible.
The most complete hardware set you've ever wanted is included so the only things you have to add are covering, power system, and radio.
Designed in the thin air at 6000 feet, the cub flies beautifully and has plenty of flying power on a simple 80 watt brushless outrunner. The plane in the pictures weighs a paultry 13.6 ounces ready to fly! (Yes, that does includes everything, even a 2S1200 mAh LiPo) It is still plenty durable and the structure was not compromised to hit this weight. Compare this plane to a Chinese BARF that weighs twice what ours does!
