Installing a brushless motor

I am new to RC Heli flying. I recently purchased a Walkera 22E and purchased a brushless motor and Li-Po battery. My question is: do I need to purchase a ESC (which I think means electronic speed controler) in order to use the brushless motor or can I install it and use:
1. The Ni Cad battery or
2. The Li-Po battery
without the speed controller.

I thought the walkera would come ready to fly out of the box. Did you mean you bought a brushless motor and a lipo battery as separate/addition parts?

Though I think it is possible to use a brushless motor without an ESC, that means you would have to connect it directly to the battery. Once connected to the battery it will run at the highest speed possible, therefore it would be dangerous to start your helicopter in the first place and also you would not have any control over it.
Sorry if this response is too late.

You need an ESC for controlling the speed of the motor other wise there's no way to control the speed of the motor; which makes flying impossible and dangerous.

Your brushless runs on a AC system, the brushed on a DC system. The ESC breaks the battery DC into AC and supplies this to the motor at the required power/frequency selected by the transmitter. The two systems are not interchangable. You WILL blow the brushless motor if you run it on DC current.
