MikeMcP, Rob47 wouldn't connect both becs, but you wouldn't know before a forensic search of his past posts or being a Mayhem member for years.
Graham.W , this is not a test. It may improve the signal to noise ratio if people like yourself, technicians, engineers, electricians, Physics teachers, or Arduino/PIC users attach one or two word answers to my list of questions.
1. Refer to the loop_current_3 gif of June 30th.
Instead of a soldered Y-harness as in the diagram, an elderly club member used alligator clips to connec the second speed control to the first esc's blade connectors at the gel battery. The negative alligator clip was knocked off. What was the result?
2. Refer to the loop_current_3 gif again.
Would shortening the length of black cable between esc negative to the Y-junction help?
3. What would happen to the proportion of unwanted backdoor current if the esc to the Y-junction was so long (or small in diameter) that it was similar in resistance to the esc to Rx wire?
4. An opto lead completely breaks all three wires from Rx to esc but replaces the pwm signal with an infra-red connection. Could such a lead supplied by Mtroniks, fitted between Rx and one of the two escs, block mutual influence as described by Rob47? (see his words)
5. Could that same device
prevent damage from an excessive backdoor current path?
6. Would any protective function be negated by adding a separate bec tapped off the drive battery used by the two escs?
7. If yes to the above, would two opto leads restore protection or noise filtering function?
My photo shows a dual 40amp esc where the second Rx plug only has the channel wire in yellow.
8. Can it suffer noise or damage in the way two physically separate escs connected at receiver and main battery could?
As a reminder:
... left motor on its stick is fine but if I try using right stick, at low revs both props turn with left direction being reversed. Once stic is pushed to higher revs both motors settle down... ![Oh Yeah <*<](http://www.modelboatmayhem.co.uk/forum/Smileys/Tug/knuppel2.gif)
