-The Precision CNC Main Frame is designed to replace plastic stock main frame on the Blade CX2 helicopters. The product is 100% CNC machined aluminum and carbon fiber to provide best precision and durability. The frame is very light, only a few grams more than stock plastic frame but very rigid and provides much better servo arrangement. Now all servos are held securely and rigidly on the CNC aluminum frame so there is no more frame flex during flight. The light and stylish high quality aircraft aluminum/carbon fiber main frame brings better performance to the E-FLITE Blade CX2 helicopters. -Blue anodizing version.
