It uses the same pwm as every other motor. It is possible to make an esc with a higher pwm bit it will also alter the performance. I dont remember what will change exactly but I think higher pwm makes a car less Punchy, increased heat in the esc (or motor, I don't remember which) and maybe smoother control. I assume there would be a limit to this increase kinda like overclocking a pc.

I very briefly experimented with putting a small container around the revolver and quickly gave up, It did very little but to create an echo chamber. I also worried about it trapping debris that the motor might ingest. It might be possible though, I put minimum effort into testing it. I was a bit exited that this item could have a cool name too, Revolver Silencer or something. Last edited by HumboldtEF; 03-02-2019 at 03:21 PM. |

You can get a similar result by gearing down and increasing motor speed with any other motor. From what I have seen the 1800kv revolver on 3s and 50:1 isn't any better then my 100:1 scx10 on a 2700kv puller pro running 4s. They have about 22,000rpm at the motor where I have about 45,000rpm. But both vehicles have the same top speed and mine seems to do better on the low end with a lower initial start speed. .

So I just did a quick test on the only similar motor I have. It's meant for an underwater thruster though so has a squeak from it's bushings but this is a 24khz pwm rate. There is still a harmonic from changeing steps but that can be made quite soft. There is no whine from pwm (Just the horrible squeak of the un-lubed bushing). https://youtu.be/2ENcO_Zp9ow |

I purchased a 1800KV outrunner knowing they were noisy. Turns out the noise was worse than I thought it would be. I used it only a short time in my #1 TRX4 and just could not stand the sound. Over the winter, I moved it to my Spartan so that at least I can't hear it out on the water.
