    It is likely due to your battery pack not being able to supply the power that the brushless system is demanding, especially if you are running an nimh pack or a lipo pack with a low discharge rating.

    What he said ^^ My E-Maxx brushless did the same thing for a while until I switched to LiPos. Even then, I still have some minor cogging...
    Make it idiot-proof and along comes a better idiot

    I'm pretty sure it's due to the fact that the motor isn't sensored.

    This would only be the case if the batteries were up to the task and if there was a stated issue of low speed cogging. Since the op isn't referring to low speed cogging, but referred to throttle lag, and only after being ten mins into the run, then i would be more inclined to believe its the battery at fault.

    Mine did that on NiMh. Improved when I added a glitch buster, but completely goes away if you switch to Lipo batteries.
    You just need more current flow and NiMh isn't going to cut it without browning out the lights which means the motor is starving too which is probably why it's cogging.
