ESC question

I am in the process of wiring in the esc's for my Engel type IX and am wondering if it would be OK to go on just one esc because with the two units I find that one of the motors runs much slower than the other.
The units I have are the Mtroniks Viper Sub10 which has a 40A motor limit and I want to run one on BEC. Would having both esc's wired in with one on BEC and the other with the relevant lead disconnected be the cause of uneven running or can someone come up with another solution
Thanks in advance

if you go to WESTBOURNE MODELS .CO.UK on the front page down at the bottom in the information section you will find wiring diagrams for single motors ,duel motors with one or two esc , it is recommended to remove one of the wires from one of the BEC the middel one as two battery supplys is not need if you are using two

I have used twin Mtroniks ESCs in this way - quite successfully.

As Willte says you have to cut one of the red wires.

I have heard mention of Mtronik ESCs fighting one another but this probably depends on model and age. I have not experienced problems myself.

there is another way of removing the red pin if you look closely at the pin you will see a small tag about half way up the socket if you push it in then push the pin or pull gently on the wire it will come out  and tape it back then if needed again just push it back in

That's a good idea. Much better than cutting the wire! (The plugs are designed for pin removal.)

I've recently fitted two Mtronix Bec ESC's to a model as follows:

A 'Y' lead was used to split the single Rx channel but this will not work unless one ESC has its Pos wire cut or removed.
To overcome any need for these drastic actions, I made up a short Y lead extension to fit in one of the Esc lines, this special has the following end connections,
1. At the esc end, a normal 3 pin connector with red, black and signal
2. At the Rx end, a normal 3 pin connector but with only black and signal (NO RED)
3. At the Third end, a TWO pin plug with Red and Black - This will outsource the Bec voltage for further use
i.e. Power to LED's for Lighting.

Why disable when you can find other uses??

Hi John,
that should be fine it's exactly what I do most of my boat have at least two esc's,but remember there is a limit as too how many servo's can be run reliable on one esc,joining the two reds together would double the amperage therefore doubling the amount of servo's but it might put a strain on the rail in the rx.

PS
just saw the comment on the speed difference when the red wire is removed from one esc,this does not always happen but it is common,another problem that can occur is running faster in one direction,I have to trim the turtle 60% 40% to get the same speed in both directions,the cure is to join the reds together,there are 4 speed controllers in the turtle and the only one that trims 50/50 is the one with the esc in use.when I get round to it I make and fit a stand alone bec its by far the best method.
