Look at "3D" aerobatic models that use 14 inch props if all you want is relatively slow movement but heavy lift for the power used.

Look at higher speed models if you want a faster quad.

You'll probably be going to standard ESCs and separate BEC or battery for the RX This depends on what (if any) other loads will be on the RX's power "buss" The stabilizer and ESCs won't draw a lot

In essence: You have to say more about what you want to do.
