This is the Curtis Youngblood Rave Ballistic 635 Flybarless Electric Helicopter Kit. The Rave Ballistic 635 shares about 90% of the same parts as the 700, but there are a few changes to make this helicopter unique to the Ballistic line of helicopters.
The tail assembly on the 635 is a shortened version of the 700 as far as the boom, supports, torque tube and control rod. The canopy is the same as the 700, as well as the gears. The 635 offers a redesigned and improved main frame for an optimized 635 performance over using the standard Ballistic main frame with a shorter boom. The auto unit has been optimized for the 635 as well, reducing weight and cost.
Thinner and smaller profile frame layout. Lighter weight, with the standard Ballistic bolt pattern. Cross compatibility with entire Ballistic line.
