If you can direct a little air at the motor you can lower the temp 10' or so. If you just can't live with it you can also put a fan on it.

Check what the stock timing is, make certain its 4 dot facing the outside of the motor , 2 dot was standard on my x12 motors and 4 dot will run better and cooler

I was setting the slipper on my buggy and while my slipper was giving being a pain in the a$$. I saw a bit of smoke come from the motor. I guessing it's some epoxy from the windings heating up I hope. The motor stills runs. Did I do any harm?

Can anyone tell me if the 1s rotor will tame down bottom end on my x12 10.5t?

Hi guys!

My Nosram Pure Evolution Spec 10,5T motor stopped working properly. The motor is not running when throttle is applied, and it works when you turn the rotor manually. We've opened it and figured out that the contact on one of the 3 phases has melted (if you understand?). We have put new contact on the phases with solder but knew it wouldn't last for long since it should be silver (if I am right?), and it lasted for 3 runs. This melted probably because the motor was running very hot (100 degrees C). The motor is also missing the little plastic shim. My question is what are the dimensions of the shim, plus I suppose it must be plastic, and am I right in resoldering the phases with silver? I'd like to be sure before I go into a DIY repair of an expensive part. I'm in no hurry because I'm running my spare motor without problems

Seing this thread has come up, I had a question : I'm running a Speed passion GT 2.0 esc with a LRP x 12 13.5 motor.
At the end of each run, my motor is crazy hot (about 110 degrees Celcius)
My current pinion is 37t. I have a 113 spur gear. My fdr is 5.9 at the moment.
When i went smaller pinion it would get even hotter, and with a bigger pinion it would also get hotter. So i currently stayed on 37t with 5.9 gearing.
Can anybody point me in the right direction, because at the end of runs, I loose power/braking ... I'm thinking of changing motor.
By the way, I run the 4 dot insert but not facing me. 4 dots facing inside motor.

bliky or boosted ? what is your soft in the ESC ?

The motor run best with the - 10, you have to see the 4 dot

Manson, the software on my ESC (Speed Passion GT 2.0) is the stock one that came with the speedo when I bought it 2 years ago. So It's not boosted, I think it's blinky.
Okay, I have changed the insert from +10 to -10. I think my motor will run much much cooler but the thing is that I now have alot less power/speed. Before, with the +10 timing, I managed to keep up with the 10.5 guys, now I will look like a sitting duck. I know slower can actually be faster, but if you had any tip on how to get more speed, what would they be ?
My gearing is 5.9 fdr on a 69ft x 35ft carpet track.

Thanks alot

Manson

Put all the timing on the ESC, stay with the -10 and adjust the FDR to not excess 90 degres celcius. I think you will be near of 5.0 fdr for a large asphalt track

Or switch your old soft for a newer...

MatJ

Okay, full esc timing got that. -10 insert also.
I guess I will adjust gearing, but how do I know which way to go ? (Smaller pinion from my current one, or bigger pinion ? How do I know which one to go for as both would reach 90 if overgeared )

And I will get newer software as soon as I get the programming card

Manson

I think 6.5 should be a safe starting point on a small carpet track. Then adjust to have a good speed and not excess 90 degres celcius.

-10 is the best way, used on blinky and boosted

Whats the size of the shims and oring that are in the motor?
