This is an optional Synergy Rail R-136 Main Blade Set, and is intended for use with the Blade 130 X electric helicopter. The Rail 136 carbon fiber blades are made exactly like your full size Rail Blades. They are designed to give your Blade 130 X the ultimate performance in collective response, cyclic response, as well as forward flight tracking that you have come to expect in a carbon fiber rotor blade. If you are looking to take your Blade 130 X to the next levelů. Put it on Rails!
