Modifying the Blade CP Pro - brushless main motor

More Power = more fun
Until you can hover in any orientation and are comfortable in forward flight and circles you don't need a brushless motor. But when you are pretty good at flying in mild breeze and can turn it around a brushless motor (BM) up front will turn the Blade into a whole 'nuther animal. Not only will it get more lift and go faster; the response to commands from the right stick (cyclic response) is even faster than stock and another bonus is that you get longer flight times with a brushless motor rated around 4100 kilovolts (kv).

Brushless motor, leads, and ESC (under the battery holder). |
My Blade uses a Park 370 brushless motor sold by E-flite. You can get cheaper motors that are just as good. The stock speed controller in the 3-in-1 cannot run the brushless motor so you need a separate electronic speed controller (ESC). The one on the helicopter in the photo above is a Turnigy Plush 12 amp. It runs the motor better than the speed controller that came from E-flite and costs less than half as much. At first I used the 'Y' connectors supplied by E-flite to connect everything. Later I dumped all excess wiring in favor of soldered connections and saved about one oz. of weight in the process. (The bullet connectors between the motor and the ESC let me disconnect the motor when I want to put the transmitter into idle up mode to level the swash plate after installing a new servo or check the positive and negative pitch range of the main blades.) There are lots of threads about converting the Blade CP Pro in the RC forums listed elsewheree on this site. The same information also applies to the Honey Bee CP2 by E-sky.
