caps

Cans the esc caps be mixed..(ie) five 35v 470uf caps...and..two 35v 390uf caps making seven all togather...and what would be the benefits..thanks

They will all add up to one large cap 4300uf that charges faster than one big 4300uf cap. Now real benfit may come if you had some small low esr suface mount caps soldered between the legs of your big caps. What that would do is because the charge and discharge faster they would be better for the smaller faster transients while the big ones would handle the BIG surges (launching, punching the throttle etc.)

So if I add the two smathank you ...what size smaller cap and how many would I need..also can i add them too the battery + - wires

Sound crazy but think of it like high power car stereo the motor is your woofer and the esc is your amp. The closer the cap bank is to you amp the more effective it will be. Id merely look for caps of the right voltage and temp rating that physical demensions will let it lay in between the legs nicely. Anything that fits will be small and good enough try to get 105 celcius temp rating. Note you miay not see any real gain in performance to the eye but your esc will like you better as you continue to filter your power supply.

Unless you got a huge setup you can run 5 of those caps on one esc and save the other 5 for another then get the 10 low esr small caps and put 5 on one 5 on the other.

I could tell you how to calculate the rc circuit charge and discharge time
but it wouldnt really help as we dont know without alot of data logging what your small transients would be and even then we would have to analyze alot of data and try to come up with a fast transient average not worth it in my opinion.Now but this is what the datalogging would give you thats worth it. you could compare the no capped run with a capped run and see the improvements in your graphical data versus seeing it with the naked eye.Kind of like sloppy bass versus tight bass in a car stereo.Some probably wont like my analogy but I dont really know another way to make it simple to understand.

Dr Wayne Has a phd in EE so definately send him a line and see what you get back hes a hell of alot smarter than me and probably can explain it in much greater detail than me but thats the jist of it. He may be out of towne right now though. He pmed me saying he was going to get a little RR . As much calculating as that man does hes gotta rest his onion sometimes though I doubt he does lol.

Lol...I get The analogy...thanks for explaining

"but it wouldnt really help as we dont know without alot of data logging what your small transients would be "

when i say would be, I really meant how fast they took place givin me a speed to look for in the charge /discharged time which would give me an exact cap rating to look for. Note these transients take place in extremely short times in useconds.
