Compass Model 7HV V2 Ultimate Edition w/Brushless Motor (510kV)

This is the Compass Model 7HV FBL V2 Ultimate Edition Flybarless Helicopter Kit. The 7HV is a unique 700 class electric helicopter that was designed by Sebastian Zajonz. Sebastian incorporated his years of experience into the design, blending a variety of innovative features into a 700 class bird that avoids unnecessary complexity. These features include an automatic belt tensioner, a sliding battery tray for fast and easy battery changes, a thrust bearing to protect the drive bearings and the swash plate, and the rotor head geometry has been optimized for flybarless operation. The single-stage transmission with large diameter mod 1.0 gears can handle the punishment of the most powerful motors and provides efficient power transfer. The direct servo-to-swash linkage rods are equal length to provide linear movement, while eliminating the angle-error and uneven movement that is found on other models.

Plus, the servos, speed controller and motor have been placed at the height of the tail boom, and the battery is positioned close to the centre of gravity. This arrangement provides a high centre of gravity, so the 7HV can perform efficient manoeuvres and can fully utilize modern flybarless systems, yielding incredible performance and great results.
