I know that many of us have had problems with the internal BEC in ICE controllers and Chris Hinson specifically told me on this plane to use a separate BEC or battery to power the RX.

Initially I ran CC UBEC off of the main flight batteries and that worked well until that Scorpion motor failed. When that happened, even though the ESC BEC was disabled, I lost control if the servos every time I tried to restart the motor in the air before I landed. The big voltage drop from trying to turn a shorted out motor or some sort of queertrons associated with that sent the UBEC nuts. It was a near disaster.

Now, I am back to what I used to believe, which is on high power setups to run your RX and Prop from two different separated power supplies.
