Damien,

To disable the BEC all you have to do is remove the middle wire (red or brown usually) from the lead from the ESC to the RX on one of the ESCs. You can cut it, or it is possible to lift the catch in the plug and pull the wire out. This means you can always reverse it it you need to later. There used to be instructions for this on the Action web site - not sure if they are still there. Another dodge is to take a short servo extension lead and cut the middle wire on that.

Barrie

PS Are you sure they have a BEC - its not mentioned in the ad. These from Hobby king do and seem reasonably priced

I profess to know absolutely Zilch about electronics and electrics in my boats, Damien, but when speeking to the owner of Electronize some time ago about speed controllers with /without BEC, he put the scenario to me of the esc blowing it's fuse if weed got round the prop and stopped working, I would then have no power to the other should it not have BEC......as I am not one for mixer boards and such things, trying to keep things as simple as can be, I have always opted for both my ESC's having BEC conected so that I have power to at least one motor.

neil.

That sounds feasible I was wondering if 2 BEC providing 5v from separate batteries would cause hassles I guess they'd just be in parallel or perhaps power both ESC's from one battery pack the motors only draw 165mA ea under load in my Sub chaser.

Fuse something used in cars lol! lol! Have never used them in a boat. Rolling Eyes Rolling Eyes
