The stock HPI servo sucks. It barely turns the wheels. So, I've converted it to TCS 1/5 scale chassis. I'm replacing the servo, and I have a $150 JR High Voltage, High Torque 7.4 Volt Servo coming

Now, I don't know much about electronics. I'm using all the stock electronics. The only difference will be the servo. What I'd like to do, to get the max torque / speed out of the servo is to use a 7.4 Receiver pack.

However since the Flux ESC is now powering the receiver, I'm not sure if I can just hook up a 7.4V 2s Lipo pack to the receiver. Do I need to disconnect the power from the ESC > Receiver first (red wire)?

Can the receiver handle the 7.4 volts? What is the stock voltage that the receiver gets from the ESC.

Do I need to use a BEC as well? I wish I knew what I was doing.

Does anybody have a definitive diagram for wiring 2 lipos with a BEC for a servo that will take 7.4V

Thanks
