The 90% prebuilt MX400 Pro performs demanding 3D aerobatics as well as larger glow-powered models do with a brushless motor and ESC aluminum parts and other upgrades providing optimum performance at an outstanding value. The factory-equipped machined aluminum swashplate and upgraded main rotor head components offer smooth cyclic and pitch control and increased throw capabilities. A direct servo linkage delivers precise tail control. The aluminum tail case includes ball bearings and a strong efficient belt drive system. Designed for brushless motors the aluminum frame provides rigidity without excess weight. The MX400 Pro is autorotation-capable with a driven tail for total control.

The X-400 Collective Pitch ARK is available in a 90% ready to fly ( pre assembled ) version. The MX400 introduces the first side aluminum frame structure design which follows the same methodology used in many of the .30 - .90 size Nitro Helis. This translates into greater rigidity and flex free assembly which ultimately allows for more dynamic flight controls with incredible 3D aerobatic performance. Coupled with a superior super smooth belt system the X-400 is one awesome machine which is revolutionizing once more the amazing hobby of Micro 400 Size Electric Helicopters !!!

The MX-400 Lightening brushless package includes high end components such as a brushless motor lithium packs and even a Heading hold piezo gyro all tested to work together flawlessly. The X-400 combo introduces great savings while offering very good components / electronics making the Lightening BL combo a great deal. This Helicopter is geared for flyers looking for a high end machine with a belt drive tail rotor. The X-400 has very stable hover and yet can produce serious aerobatics with ease and smooth collective control.
