Battery/on/off/charge lead for esc's with no battery eliminating circuit.

Hi there,
hows about a battery connection and not BB but  8/B as in 8 channels - so if you want to use 8 servos in this receiver, you must plug in a 'Y' lead on channel 8 and then on the other end of the 'Y' lead you connect one servo and one battery pack and that is, unless you are using a speed controller that has a built in BEC John

There are eight sets of pins numbered 1 to 8 plus an extra set marked B for battery connection.
Designed for flight, the motor would probably been IC and throttle controlled by a servo hence no bec.

Thanks chaps. One more question. With know battery wired to the reciver how do the servos get their power. You can see I am new to all this.

The pins the battery connect to are linked to two of the pins at each servo position so the servos are connected to the battery.

If the speed controller you are using has a battery elimination circuit (bec), the lead from the controller also carries the voltage to power anything plugged in to the other pins on the receiver. If this is the case, a battery should not be plugged in.

Thanks, so if I have this correct. A bic system allows the receiver to draw power from the speed control. And a none bic system needs a battery connected direct to the reciver to provide power.
