What is this slipping?

[zukicidal]

I took a little video of my issue. The rear diff is nice and tight, only a little play. The motor spins fine but when there's resistance on the wheels it hesitates. Is it the slipper clutch or electronics?

Is your gearbox trashed? Have you opened it up?

 

[zukicidal]

I showed in the video that the gears are good. It must be a motor or esc issue.

It's not an issue i have that really bad on my torment. That is because sensorless brushless systems do that when they are under load at low speeds. Cheaper or lower quality systems have a hard time operating in high stress environments. It depends on how your motor is built. If your motor gets hot feeks like it burns to the touch after a run you might have to go down in gearing.

Thanks for the reply! I will try gearing it down

 

[zukicidal]

I geared down and it's better. Thanks.

Just my 2 cents slipper clutch is slipping replace slipper clutch pads

I geared down and it's better. Thanks.

What esc and motor do you use?

I've throw money at issues like that, only to find I had defective battery....

What ESC and motor do you use?

It's a goolrc brushless. It's working a lot better now that I geared it back to a 19t pinion. I didn't buy it here but this is it-

So far it's been a reliable setup. I added a heat sink to the motor since it's really hot where I live. It seems to help.

Actually mine is a 3930kv

I also have to mention that having high C ratings helps my motors work better under loads I tested my 20c to the 40c. The 40c seemed to work better in the grass and did better wheelies. If you know the max amps of your system try to get about half of that with the batteries constant discharge for good bashing. For racing I would try to get a battery close to the max amps for the most power. If you have a battery with too many amps it doesn't really matter nothing bad will happen. In other words if your motor is cogging like that try a higher c rating it will help and boost power.

Lets say...
Max electronics amps = 200
Battery = 5000mah or 5amp
discharge = 40c
5x40=200amps constant
Max discharge is around double 400amps = good racing battery

A good bashing battery would be a 20c if you arent going full throttle all the time.
