Power source for receiver
Hi, I have gone to electric but need some basic help, does the Li poly also supply power to the receiver or do you need a separate battery pack. If the Li poly supplies the power, hows it get connected, through the throttle channel or what, please advice. The manual I have is extremely vague.
Regards
Frank

RE: Power source for receiver
Most ESC`s (Electronic SpeedControllers) supply the required voltage to supply the receiver and servoes. And as you mentioned: through the cable which is connected between the ESC and the throttle-channel of your receiver.
Remember: Opto ESC`s do not supply this voltage. And there is a max limit of how many servoes you can run this way. Usually the max number of servoes is 3 when you run on 3S LiPo. On 2S you might run 4 servoes, and with 4S or larger LiPoes you need to add an external supply and disable the internal supply from the ESC.

RE: Power source for receiver
joo has provided good information. Here is a bit more.
Most ESCs have a built-in Battery Eliminator Circuit (BEC). The BEC is a voltage regulator that reduces the battery voltage to a level that is safe for the receiver and servos, usually 5-6 volts. It's called a Battery Eliminator Circuit because it eliminates the need for a separate battery to power the receiver and servos.
So, you plug your battery into the ESC. Then you plug the "servo" cable from the ESC into the throttle channel of the receiver (usually channel 3). See the diagram below.
As joo said, there may be limits to how many servos any particular BEC can handle. So if you have more than 3 or maybe 4 servos or are running more than a 3S lipo, you may need a different solution.
