Tp 4070 2250kv Heat Sink and Fan suggestions??

the xlx2 has 2 cables that you need to plug into the rx. Other esc's only have 1 cable. The 2nd cable is the aux cable and it apparently allows you to get more amps to the built in bec and also allows u to set up an esc function on your radio. For example, I use a radiolink radio and I have the "max power" esc setting bound to a dial on my radio. Basically acts like a throttle limiter in case I want to hand the radio off to someone else or I just don't want full power.

Once you read the lil instruction booklet you will understand

I just bought a FlySky Noble 4 with receivers. so i will have to install it as well.
