A while ago (21Oct2007) I asked this forum how to disable BEC in ESCs. The Thread is 6518113. Even Umi offered some advice.
I did as recommended and disconnected the red wire. I am still learning a lot more about them thanks to all the comments.

Question.
Why does either circuit work without problem if only one is in operation, yet has random dropouts "disarming", if both circuits are put into operation?

If it is down to the D cells, then the ESC should drop out even if only one circuit is working.

In last night's testing I ran each circuit separately - right down to stopping (ie low battery) but neither ESC cut out.

The ESC's only work with the ESC switch turned on.

There is a copy of the ESC's instruction sheet with the original thread. Worth a review.

I thought that the NiMH batteries were the best for the purpose (apart from the LiPO), is this not the case?


Is there a better way to disable the BEC? or not have the main batteries to power the ESC circuitry


I worked too late tonight to have time on the boat. Suppressors are still top of the list.
