Does anyone recognize this set up? This is an AXE CP tail rotor assembly on a Blade CP. The bore in the Axe tail rotor mount is 5mm so it is a direct replacement. This motor has a LOT more authority than the stock blade motor and it seems to be very durable. I don't know if it has any benefit over any of the other set ups, but it is one of the cheaper solutions. The Motor is expensive, $24, but the motor mount is only $4.49 and I think you can use the Blade gear, and shaft. The bearings appear to be a tiny bit different so you will have to purchase them as well. Helimax does not sell just the tail bearings, only the complete set. I didn't put the ampmeter on it so I can't tell you if I'm cooking the factory esc or not. I can't imagine that it would be any harder on the controller than a dual motor set up but I have been wrong before.
