i ended up finding something on you tube and changed out the rotor, but the kit came with a couple different spacers and one o-ring. i just used the same spacer as the stock rotor. is there a reason why there are extra spacers for the rotors?
also noticed that stock rotor has four holes drilled into it. check the picture out. is that a mod that people do or is that from the factory like that? the green rotor does not have any holes in it. BTW, I bought the motor used.
Thanks

The red and blue rotors are the same diameter, but the magnetic material on the blue is something like 1mm longer than the red, so different spacers might be required.
The green rotor is the same length as the blue, but has a larger diameter by 0.2mm.
Just take the original apart and when rebuilding with the new rotor, remember to put everything back, especially the huge fibre 'washer' at the sensor board end.

Try a 3.9 FDR as a starting point for the green rotor. If you try the blue rotor, start at 4.0. I used a 3.8 FDR, green rotor and 35 degrees of timing on a 100x40 track, and was very competitive using these settings.

thanks for the replies on the rotors.. I put eveything back together with the new spacers and o-ring to match the red rotor. hopefully everything will be ok. i will find out when i run it this weekend. if i run into some problems, there will probabaly be some guys at the track that can help me out.

Having some issues with my 8.5T. It's really loud. It doesn't get hot or anything but when it runs you can hear that it doesn't quite sound right. I've had it for about a year and I've never done anything to it except blowing the dust out of it. What could be causing the noise? Also, the tabs are moving side to side just a little bit. Is that normal?

I added another of the fibre shims to the sensor end from another TP motor, problem solved (add another small shim to the pinion end of the rotor shaft to compensate)

I had a motor where there was a little play in the stator as well, that's probably the sound you're hearing.

Anyone got a good configuration for 2wd stock buggy?

Just replaced my 17.5 red rotor with the green rotor for my 12th scale. The track is 83x40, which starting gearing should I use with 42.5mm tire?? 35 degrees timing, correct?
For TC i used the blue rotor that and it worked out well but I'm curious what I'll get from the green in 12th.

These motors seem pretty fast !!!!
