NX7 This is what you have been waiting for!

NX7 Formula Rotor head contains the central pivot bearing support for the Rotor Head Spindle Shaft which offers a crisp and precise feeling. The NX7 utilizes high quality 3K Carbon Fiber frames and implements a narrow body design for maximum strength. 131 tooth M1.25 Main Gear (same modules as the X7) Fuel tank placement is exactly in the center of the main shaft. This allows the model’s Center of Gravity to remain unchanged through the entire flight.
The oversized main gear design allows for a proper model CG (with Direct Drive servo input) and provides more torque from the engine. The one piece CNC Machined aluminum tail case provides easy assembly and maintenance with black anodized “X” series laser etching. High strength one piece engine mount with U shape mount that connects the engine to the bottom carbon fiber plate. This secures the engine in place and allows for maximum power transfer between the engine and the rotor head. The NX7 utilizes a red CNC Machined frame side bracket which improves power transmission efficiency and provides an excellent aesthetic appeal.
