Lol upgrading the capacitor count won't increase the brakes.

lol... works for me. Have you tried it ?

I don't need to, I understand the basic premise of increasing microfarad in a capacitor. Also another thing, why wouldn't you go with a slightly larger capacitor? It would save on space and effectively be the same.

Maybe instead of some vaque anicdotale statement, you provide verifiable proof of your wild claim?

I've tried increasing the capacitor size to get more brakes and it doesn't work. Only thing that worked was motor change. I even changed rotors in the same motor, all the way to a very strong magnet (1700+), and that didn't work either.

My point was why go 4 smaller capacitors in parallel instead of one large one?

​​​​​I also wanted to high light how silly these people are 4 caps have a much larger foot print than 1 larger cap. TC are already pressed for space so why take up even more with 4 caps on a circuit board.

Which ESC do you run? Have you made any adjustments to things like braking frequency?

I can flip my 4wd buggy on the brakes this speedo has! do this...............set EPA for throttle and brakes all the way up, I think its 150 on your radio, then recalibrate...

If that's actually required to get the ESC to calibrate the full range of brakes properly, then there's something wrong with the calibration routine.

I think some people need to read the manual

I think that depends on the software in the ESC. I can easily imagine there are no "checks" on input limits. Especailly with how ESCs need to calibrate themselves to crappy signals coming from radios. It's totally worth trying.

That still makes no sense. If the ESC calibrates maximum braking to one level of signal, then receives a higher level, it can't violate the laws of physics and just brake harder. If it's not already braking as hard as it possibly can at the calibrated signal, it didn't calibrate properly.
