For some reason... any plug clip with wires, the wires WANT to get in the prop. You have to place the battery behind the wing, and back far enough that the wires don't have the room to let the plug clip rotate forward due to engine vibration.

This is one reason GAVE AWAY my power panel... with the starter plugged in, and the glow driver in use... I had to have one set of wire rnning around in front of the prop. That's asking for a wire to get in the prop. I feel that having to actually hold a NiCd glow ignitor on top of the engine is safer than running wires near the prop...
