1.5amps will only be enough for a 1/10 ST IMO. I have found that a BMS-620mg, no matter the vehicle, will pull so much current that the voltage on my 7805 will drop low enough to where my Novak XXL will send a signal to the servo that makes it just keep turning, then re-centering, and so on.

I could do the sort of thing where the controller would be plugged in-line with the BEC unit. This is because everything that plugs into the receiver shares the same positive and negative! What I am planning on doing with this particular circuit, is I will combine it with a LVC device that I am also making, so both will be on one circuit board, eliminating extra wires. And it will go in between the controller and the receiver. The LVC will cause stuttering of the throttle when the battery gets low, and the BEC will do what all BECs do.
