I have a couple older LRP esc's that have issues and was hoping it may be a simple fix. Both esc's have the exact same issue. One is the Sphere Comp and the other a Sphere Comp TC Spec. Both appear to be in good condition and I installed a new LRP wiring kit on both recently.

The problem with both is that they run great for the first 5 or so minutes. After that, they start to cog fairly bad. Doesn't matter what speed either. They just start twitching and cogging all of a sudden. Sometimes they will start running fine again on their own after a few minutes of cogging and other times it just gets so annoying that I stop running.

I've tried a bunch of different motor, sensor wires, receivers, even tried them in different vehicles and it's always the same thing. I really like the way these things run (when they're running correctly) and am hoping there may be something simple to check out before giving up on them.

Thanks in advance for any input!
