The Mountain Models 1/9 Scale L-4 Grasshopper was CAD designed to be a lightweight, super easy to fly, laser-cut, scale electric parkflyer. It is the only complete electric L-4 kit on the market.

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 15.5 ounces ready to fly! (Yes, that does includes everything, even a 3S1000 mAh LiPo) It is still plenty durable and the structure was not compromised to hit this weight.

This plane is what relaxing flying is all about!
