A new addition to the family!  The Rush 700 Nitro (Katana) by Evolution Helicopters is our first nitro helicopter release.  Based on the proven building blocks of the Rush 700 Evo platform such as the ultra responsive rotor head, direct-servo setup and torque dampen auto-rotation hub, the Rush 700 Nitro delivers a whole new level of agility, transmission efficiency based on new innovations in engine performance and new thinkings such as round shape fuel tank to the 700-size nitro helicopter scene. Like its 700 electric counter part, the Rush 700 Nitro is ready to be to a 750-size (using 750mm blades) with the optional stretched kit. So, the sky awaits you to dominate.  What are you waiting for?
