6) forgot to ask, will using caps that are closer to the battery voltage (7.4v-11.1v) be more efficient than higher rated caps with the same volts? say 16v caps vs. 35v caps...


If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...

About the only thing I can answer is the question 6. Using caps with a smaller voltage doesn't really help electronicaly, but will just make them smaller. I think it would be safe to use smaller voltage caps, not sure about more UF, but I can't really see why it would hurt the ESC if the caps could hold the voltage longer.
I'm not a complete expert, so don't do anything untill you hear from BrianG. He should know a lot about the caps and interference etc.

In general caps must be rated at list 25% over max operational voltage. In case with BL motors you need to add BackEMF...

With proper technique you can reduce 25% margin to 5%.

For the rest:

1. No
2. No ( I provided the link for the proper replacement, what's wrong with that part? )
3. Yes, very bad
4. Yes, as long as wires are short, and caps connected on ESC side of power connector.
5. Can you draw (schematic or smth) of what you planning to do?
