no, unless you are using a Hara Twister or KO speed control.

I'd use one any way, on every speedo just in case. It's not going to harm it if you do put one on

LRP IPC Sport Digital and quantum sport. There is no braking involved on the local track.........unless you are headed straight towards a wall!

I'd put one on just to be on the safe side. If your in a crash or you hit the wall it may help the life of your speedo, there probably is some arcing when that happens so it's probably safer.

The quantum sport was just sent in for repairs after a crash! Both have had diodes installed. I am wondering if they are needed or not.

I agree - as long as you DO NOT HAVE REVERSE I would use one.

I mounted a Novak diode directly to my Quantum. Takes up very little room and I don't have to solder/de-solder them on the motor all the time.

to filter motor spikes between 1% to 99% throttle range.
to absorb excess current while coasting and braking. In short it makes your ESC runs cooler.
