But read manual to find warning about extra battery pack. It's on page 4, LH corner. maybe some one else has more info. Just wanted let you know about the warning. Also look into a "Pico Switch" It is a switch which plugs in to the receiver for say lights. Search the forum and internet for it. Good Luck!
Sorry so long.

Thought it might help to explain some basic RC tech...the servo cables have 3 wires....red for power supply +ve, black or brown for -ve, and white or orange for the signal. Inside the receiver, all the +ve pins are connected together and all the -ve pins are connected together so all the servos (and the receiver itself) get the same voltage. MFC has an internal voltage regulator, like many (but not all) ESC, which takes the 7.2v supply from the battery pack and provides stable 6v to the +ve (red) cables which plug into the receiver. That's how the receiver gets it's power with the MFC (same if you use ESC with 'battery eliminator circuit' or BEC, which refers to the fact that you 'eliminate' the need for the receiver battery pack). If you then also plug a battery pack into the receiver, you effectively plug directly into the MFC (because all the +ve pins are connected together in the Rx) which then competes with the MFC voltage regulator....something's gotta give, MFC pops! So do not use additional battery pack for receiver when you have MFC (or ESC with BEC)
