motor temp is around 130 f.

any ideas which way to go
At Snowbirds (100 x 40ish?) ran a 4.10 with min motor timing. I'd say pull all the timing out and start around 4 flat.

But what do you get if you flip the 2 dot?

i am running it in boosted, with insert they came already in motor. temps were around 170-190 degrees. this should not be a problem for the LRP should it?

You're not even close to smoking it, but anything over 200 and it will fade pretty bad. I've seen peeps run the LRP motors over 250 without smoking, but they fade really bad when getting that hot. The reason I like the motors is that you can be off on the setting, get the motor too hot, see the car is fading, and pull off/slow down etc...without damaging the motor. Every Epic motor I've run lets you know its getting too hot by smoking. Yeah the epic motors run cooler say 150ish, but they smoke at 175. The LRP motors run at 200, but don't smoke until over 250 and there is plenty of warning before they let go.

My $.02

The first thing I would do is change the timing insert, reducing the motor timing as much as possible. Then try it again. If the temperatures are still over 160, reduce the ramp of timing in the speed control. Continue reducing the ramp until the motor runs the entire run without fading. Good luck.

I am running a X12 17.5 with a tekin rs in blinky light mode. I tried it with the two and four dot inserts and the motor was around 175 both times. I am geared at 96/47 in a Xray T3 2010. Any suggestion what I am doing wrong.

175 is perfectly safe with the X-12.

Default X12 10.5

Which is the best combination 1s 12.25 rotor or the 12.5 rotor. Using this with the new SXX stock esc. corrected

Clarification: The motor comes with a very strong 12.5mm diameter rotor. The 1S rotor is not as strong and is 12.25mm diameter. I think you have a typo there.
