I'm about to start a new build and it looks like things have moved on a bit since I built my last RC model - which used a Mtroniks Viper 15 and a Planet T5 tx/rx. In that model I have the ESC connected to channel 1 and use the BEC in the ESC to power the receiver - all good. But looking at different makes of transmitters and receivers, got me to wondering whether a receiver would be powered from the ESC's BEC if connected into ANY channel ? (Although I guess in most systems, throttle is typically channel 1 anyway)
Also, what are people's thoughts now on using BEC from an ESC? Is it preferable to have a separate power supply for the receiver? My new model will be using a 12v SLA with an Mtroniks Viper 20 driving a MFA Torpedo 800 motor, would there be sufficient power for the receiver and rudder servo?
Many thanks in advance for any help !
