thanks for such quick replies...the system and motor runs fine when i take the system out and run the motor with or without a pinion against "air"...
i tore down the motor and 2 questions: 1. Are the magnets supposed to come apart (there are 2)? and 2. I used locktite to keep the endbell on...will this mess up the motor?
....when i take it to WOT the motor runs smooth with all three battery types...it also took removed the esc from its casing and i see no burn marks as well

...by the way, i have no idea who makes the spur i'm using since it came with the revo after i bought it off ebay a few months ago, its pretty sturdy and i have not stripped any spurs or pinions....

...i still don't know whats wrpong with the motor being that it only went through 5 runs....twice on 3s (fast)...twice on 4s(faster)...and the one and only final time on 5s (

) this thing was fast!!! and "WAS" being the key word now at least until the NEU comes in....
