Still a bit confused if I need a BEC

[_paralyzed_]

you have to power your radio reciever and servo(s), you do that either directly from the speed control (the red wire in the three wire plug from the speed control to the reciever) or with a battery eliminator circuit.(BEC) Now, you can only power the reciever once, so if you plug in both speed controls you must cut or pull one of the red wires so only one speed control sends the reciever power, or pull both red wires if using a BEC. Do YOU need a BEC? Only if you speed control doesn't have one, or you are using a mamba max above 3s, a MMM doesn't need a BEC, what speed controls will you be using?
