The ESC the plane comes with is perfectly fine... the problem is that on ANY "Linear mode" BEC, which this ESC has on board, the maximum voltage the BEC can handle is 11v... Even at 11v there is not much capacity left over for multiple servos.

Very expensive ESC's use a SWITCH MODE on board ESC, but this costs significantly more as there is a whole different set of electronics involved.

Standalone BEC ( battery eliminator circuits ) that can power the receiver and servos can be purchased fairly inexpensively...

However you would have to wire it in yourself.

What I do in this situation, is I purchase a suitable BEC of greater capacity than I need... such as one of these bad boys...

And also pick up a male and a female Deans connector plus a bit of suitable shrink tubing.

I set the make and female Deans connectors back to back with the appropriate polarity observered and solder them together.

I then solder in the BEC's red and black wire to the middle of this new "shunt", again observing polarity, and cover the whole thing with heat shrink tubing. The tubing must cover the exposed section of your new "shunt" so it needs to be at least 1/2" in diameter or more...


This takes me about 5-10 minutes to do, but I end up with a removable BEC that I can use for other planes and applications later.

Basically the BEC is plugged into the battery, and the ESC into the BEC's new shunt.

The servo style lead of the BEC goes into an unused receiver port to provide power to the RX and servos.

The servo style lead of the ESC get's it's red wired capped off or cut so it no longer provides voltage to the RX/servos and it is plugged into the throttle channel port.

This sounds more complex to do than it is, but you should have minor soldering skills to tackle it.

Of course anyone interested in RC - NEEDS - soldering skills amoung other things, so most hobbiests have no problem with this.
