Turnigy Trooper with violent cogging
Hi guys,
I'm having an issue with this Turnigy Trooper. I've upgraded ESC to a hobbywing 150A and a tenshock SC401 4600kv motor. Gearing is 15t pinion and 44t spur 17mm hex upgrade. It seems to cog way too violently when driving slow but once you accelerate hard, the cogging seems to go away. I understand that most brushless motors cog but this is way more than I've ever experienced. Diffs are fine, gear mesh is fine and motor + ESC are brand new. Any suggestions as to what would be causing this? I've taken a video of this to demonstrate the problem but I can't seem to post it here?
Cheers

Are your other motors this fast (4000+kv)?
Cogging gets worse the higher the motor kv so... Just an assumption

I ended up putting the mmp back in and the violent cogging went away instantly so I'm assuming its a problem with the hobbywing esc. Unfortunately though the mmp overheats after a few mins running the tenshock motor so I cant win

Try gearing down to stop the overheating. Once the correct ratio is found, use the HW esc again. The cogging could be due to too much load.

where do you buy spur gears ?
