MMM Combo 2200 a lot of cogging...

Maybe I expect too much ... here is a video of the "cogging" Castle 2200

You are just at very low throttle before the motor breaks the magnet/ pole attraction- so it looks to me. Once it is above that minimum rpm do you have any studdering issues?

Yes ... the studdering is only at a very very low throttle .... When the motor starts I have no issues ;)

That is not cogging! Have you tried it in your car? Motor/esc needs a minimum RPM to establish rotor position and function properly. cars/trucks/buggies all use gear reduction so that's not to much of an issue. I have aprox a 13:1 reduction on my REVO so every 13 turns of that motor only turns the wheel once. without a load on the motor you are going from nothing to about 20,000RPMs!

i believe if you change the pinion to 13t the cogging will be much less due to gear reduction and the thing will still fly.
