I need some help with my Momba Monster

[JohnnyT1992]

I built my E-Revo and i am about to take it out for it's first real run. But i am haveing a little issue, I dont know if it is normal or what. But when i give it veary little throttle to drive slow it will drive slow for a few seconds then it will get a burst of speed and stay at that speed untill i let go. I dont know why it dose that. All my settings are at default except for my cells i put at 3.4v and 50% punch controll and thats all. My gear mesh is fine too. I dot know if it's my slipper that needs to be tightend or if this is just someting the MMM dose. I tightend my slipper a little already because it was too loose and it's not makeing the sound it made when it was slipping. So i dont thing it's the slipper. I hope you guys can help. I'm about to run it and i will check back in a little bit.

try resetting the throtle end point....forward, break, neutral
check slipper can you hear it screaming
is it just the motor cogging from a start??

Whats the end point, And how do i reset it? And when i give it a little throttle it cogs a little untill the motor starts spinning and then it just gets a burst of speed. It's hard to describe.

It sounds like standard cogging on a sensorless motor like the MMM.

Okay, I just reset my setting again and set the volts to 3.4v and punch to 50%. Then i redid the TX calibration and it still dose it. I myself think it's normal, But i never used a MMM before so i dont know for sure.

anytime you change a setting with Castle link you need to reprogram the ESC...(set points)

increase ~ decrease the punch control it will help, & the MMM has some cogging from a stop. some what normal...
a sencered motor is much smoooother from a dead stop...

Thanks, I did not know i need to reset it after every adjustmen.

All of my castle stuff does this, I figured it was normal for a sensorless system. Even my mamba 25(castles first mainstream ground brushless system) for my 1/18th scale trucks I had many years ago did the same thing.

maybe a video would help...

This is natural for a sensorless system, as it's the motor/speedy leaving EMF.

Thanks guys, I drove it the other day and it ran so great. It must be normal, Outside i did not really notice the little burst of speed when i was driveing slow slow. It was really when i was driveing inside to test it.
