Question
Does power need to be regulated with a 4S lipo on a JR921 rx?

I am new to the bigger electrics and want to use a JR921 rx on an electric with a 4S pack. The pack is rated for 14.8 volts and I believe the rx is only rated for up to 10 volts. Am I off base here? Thanks guys...

Doesn't your ESC have a BEC?

4s is too much voltage.. I would look at a castle BEC-- something that can handle the number of servos you plan on running and deal with the 4s input voltage..... Or run a small 2s pack for the receiver/servos only.. Do you have high voltage servos??

Your ESC should take care of it.

Thanks guys! It will be an Airboss 45 Elite so I'm sure it will. I didn't understand the chemistry of how the system works, but I got it now.
