ezrun 35a coggin help
 

is there any way to stop the cogging on these escs im using the 9t motor with old 4500 nmih and old 3300 it coggs and cuts out as soon as throttle is pressed.

Lipo's help, but mostly its down to gearing. They only cog badly when overgeared.
Remember, this is a cheap 380 sized rotor in a can finned to make it 540 sized. Although its a 9turn winding, its performance is closer to a conventional sized 10.5T, but with less torque. The result is that its quite easy to overgear it attempting to match the speeds of those with bigger, more powerful motors.

Start with whatever gearing is recommended for a 19turn brushed in your car. And don't forget it is a sensorless system , so will always cog to some extent. However, set up right it should be barely noticable except at crawling speed.

i have a ezrun motor and esc, they will cog if the are advanced to much as well as being over geared. you could try retarding it one step back and see how that is. also they dont like a low battery and will dick around to make it feel like it's cogging.

i have read that others have had problems, but mine has been trouble free:thumbsup:
