I'm not sure, but I think "none BEC" just means there is no BEC in the receiver itself. Even if it meant the receiver is not BEC-compatible, the way you had it hooked up is fine (BEC in battery slot).

I can think of several reasons why the BEC got hot, in order of probability.:

- Servo overload. If a servo was stalled (like steering trying to move beyond the mechanical limits), it can pull quite a bit of current.

- You hooked the BEC input to only one of the battery packs and used the wrong one. Most ESCs (if not all) have a common ground connection between the negative battery pack connection and the throttle ground connection. If the BEC input was hooked to the wrong single pack, the ground was actually at 1/2 the battery voltage.

- Defect in the BEC itself.

- Reverse polarity on the BEC input. I don't believe this is the case as it wouldn't work at all if this happened.
