Title: Cutting wires, DON'T!
Post by: wartsilaone on March 09, 2011, 07:41:50 PM
Don't cut the wires your expensive BEC type ESCs. Buy a short servo extention for a couple of quid and cut the wires on them. This will future proof them should you wish to use them in another model.

Not thats its not a bad tip, but why would you cut the BEC/data leads on an esc in the first place? if you need to have more reach on the lead use a standard servo extension cable.

Only time i see that its worth cutting the lead down is if there is a break in the cable and you have managed to locate it to fix..

If your trying to stop the BEC function just un-clip the central wire (yellow/orange) from the plug and wrap it with some black tape or heat shrink.

I didn't want to do anything with the ESCs as this may void the warrenty

Centre wire is normally red  :-))

If your using two speed controllers you need to disable one of the BECS :-))

You,re not getting the point i was trying to make which is, Why ruin something that may cost as much as 30 when for 2 more you can have what is effectively an adapter and you will have more options when configuring your radio setup.

Or get a marine ESC that has a jumper that disables the BEC.

Yes it does depend on the make. My Mtronics ESCs don't have a switch that disables the BEC function. You get what you pay for!

Why can't a good, simple piece of advice be accepted for what it is?

I agree with Wartsilaone on this method, but at the end of he day, it is only another option that others may not have thought of.

The first thing I do to most of my ESC, is cut the power switch off, and solder a plug on the ends.
This way, the BEC is disconnected if need be, however, I usually solder a long wire onto the switch, then
mount it somewhere on deck and plug it back in.  The wires have to be cut to put plug, and then run a
lead to where I want my switch anyway.

As for extending the receiver lead, it is cheaper to clip it and solder in an extra length of wire than to buy
a servo extension lead for $6.00...

I don't think that the original point was to extend the lead.

It was simply a suggestion of method of disabling the BEC without affecting the original ESC wiring.

I use a tiny screw driver (just like Dave show's on his link) to remove the center wire from the plug , it can then be replaced if needed , even the manufacturers wont notice what you have done.
As for the servo extention leads , yes they are a good idea but where are you guys buying them from 2.00/ $6.00  :o ,
the last lot i bought from the bay worked out at 20p each , and i have not had one out of the batch of 50 fail .
