Sale price$789.26CAD


One of the most revolutionary helicopters of today. The Raw 420 has an incredibly large, direct drive motor offering superb performance for 3D pilots and incredible efficiency for sport flyers and beginners alike!

This little heli is designed to run on a 6s pack ranging from 2200 to 2700 mAh and comes with motor and blades. You simply need to get servos (micro cyclic & mini tail), an ESC and a flight controller! We recommend either the HobbyWing 60 or 80 amp controllers or the Scorpion 06_80. All of these are excellent choices, if you are planing on doing mild 3D or sport flying, the HobbyWing 60 is the best choice, for harder 3D, then the 80 amp ESCs are preferred.

The kit ships with one battery tray, make sure to get more if you plan on having more than one battery ready to go.
