LRP TC with KO FET SERVO
 

I am wondering where to attach the fet wire that comes out of the servo should I put it on to the red servo wire that comes out of the speedo and goes to the receiver. All advice required, many thanks. MARTIN.

the extra input wire of the Fet servo should be connected to the 7.2V battery +ve terminal.........in order to get it's maximum power..........

if you connect it to the receiver red wire ........the input voltage is only 6V (or less) rather than 7.2V.......hence less power output......

hope this can help you.......:)
