Help needed

[SV6000]

Hi Guys

I need some help with my G3R build. I have not touched this thing in ages and blew the dust off it to drag some Helis at the flying field. I was doing some routine maintance and when i pulled the motor off i noticed a couple of pieces of the wrapping that goes around the stator fall out. When i turn the motor shaft with my fingers there is very little resistance, and when i hook it back up to a speed controller it runs normally.

Have i cooked this motor??? OR spun it too hard
Do i need to send it in for repair???

Now if i send it in my choices are repair this motor or get another winding of motor. But seeing how this was a speed truck build i am unsure of what to do.

I am running a 1527 1Y on 12s. I have always checked my gearing and temps to make sure the thing never got too hot, the same goes for the speedy and batts.

Should i repair the 1Y and retire this as a full time speed truck and run it on 6s-8s or should i opt for a 1.5Y/2Y and run full time on 12s


Please chime in and give advice
