LRP Vector x12 Brushless Motors

On old software try 4 dot timing, 30-88 gearing on profile 5 not sure how that compares to new software, Maybe someone on the BD thread can tell you.

Hello There,
Does anyone have a LRP X12 8.5 Brushless 1/12th setup in the sensord mode? And what Spur and pinion should I use?
Here's the track size and my car info:
100"X45" Feet
1.72" inch rear tire

Ok can someone shed some light please. I had a new 4.5 x12 geared at 8.4.(on road med to large track) Ran it about 6 times at our state title race and in the finals the rear bearing blew apart. So i stripped it down cleaned out all the debris as best as possible and ran it in the next run. I got to the end of the run and it just stopped. A motor wire unsoldered. This tells me it got pretty hot. Is the motor stuffed? The rotor has a few scratches on it too.
Cheers

However, the motor may not be totally stuffed. Clean it up again carefully, replace both bearings (cuz' for sure the second one will end its life shortly after) and apply high quality lube regularily.
X12 weak point is the bearings...
You have to check their conditions every 6/7 runs. If the motor gets hotter than normal, starts being noisy, or too much play appears on the shaft, bearings have on their death path...

I wouldn't run this motor ever again. It is not worth the chance of blowing your ESC. You can try sending the motor back to AE for service, but most likely the warranty would be denied and you would have to pay a reduced replacement charge.
Our X-12 motors (4.5 / 7.5 / 13.5 / 10.5) come off the track between 200 - 220 Deg F. every time. These motors run extremely hot compared to other brands. Plus we run a high flow fan and modified the cans for more cooling. The motor quality is great and there is no degradation of performance when they get this hot. We have seen X-12 get over 260 F and still work flawlessly after cooling down.
If you race competitively, high heat vs. performance is the nature of the game. Therefore, you will have to bring 1 or 2 back up motors if you don't follow a rigid maintenance schedule.
BTW, we clean and oil our bearings in our LRP X-12's before every race/practice event. We replaced several with ceramic bearings but find there is no performance advantage.
Both bearings are larger in the LRP X-12 Stock (10.5/13.5/17.5) which have the bronze can.

The LRP-X12 use a very high temperature silver-based solder. Much better than most motors out there. If you were able to get the motor that hot and unsoldered it, then you pretty much toasted the motor permanently. A scratched rotor will be most likely not be balanced anymore therefore causing future bearing problems.

Anyone want to help explain the difference between regualr wind and octa wind, still don't quite understand. Also, is there any performance difference between these and the x11s.

My motors come off at 150-160F every time

What is the easiest way to lube the rear bearing?
