@CraigM: he hardly ever runs 6.5t in his 4wd actually, normally he's on a 7.5t in 4wd... Anyway, he runs both with the lowest timing (oooo insert).

The motor ran great, had great power, and gave no signs of failure until the melt down. I've had it about 40 days....am I SOL or will they replace my motor for me?? If so, contact info appreciated.
Wanted to report back that LRP did warrantee the motor and sent me a free replacement. I took the 8.5T since the 5.5 was out of stock and I had already replaced it with the new Balistic. I'll try that in offroad this fall, and will be ordering some ceramic bearings to be on the safe side.

Took a while, but they did what was right, and I'll continue to support their products. This is the first real issue I've had with LRP products, and I have 4 various LRP speed controls and 1 other X11 motor with no issues in a couple of years.

Great to hear that and LRP oso replacing my motor which has some slight issue. Great company indeed. It's right to have bought their product after all.

Default Supposed to run with 'oooo' timing insert?

Hi. Just bought my X-12 today. Its a 5.0turn and came with the 'oooo' timing inserts installed. My question is whether we are recommended to run with this -10 deg timing ?

And whether it will somewhat reduce the heat issues related to the X-12?

Finally are there are other difference between the 1st and 2nd batches of motors (ie different rotor design or better bearings)?

Thanks in advance for any inputs given.

It's best to start off at -10deg timing and the gear ratio follow manual. Then do check the motor temp. I've compared older batch v new batch motors are slightly bigger vent holes on the new motor, old - 4mm; new - 5mm.

have fun.

Thanks. Can anyone provide the ID/OD/thickness of the X-12 bearings so I may be able to source for some ceramic ones? Don't seem to be able to find this piece of info in the thread.

I think its 4mm x 10mm x 4mm. I ordered mine from BOCA but yet to received yet. Its been almost 3 weeks since they posted it but that is understandable coz I live in Asia, so shipping from the states to here maybe take a little while.

Yep, I can confirm that. I checked bearing after getting motor and it 4 x 10 x 4.

Cool. Thanks guys. Is the rotor hard to assemble back after striping the little bugger to change the bearings? I experienced quite a bit of difficulty with other makes when trying to slot the rotors into the bearings when assembling.

Ya, it takes a few tries to get rotor back into end bearing but it's doable. I ended up using a set of pliers to hold the pinion end of rotor to help hold and guide it in and that helped.

The easiest way to put-in a rotor is to remove endcover and sensor-system first (it's only 1 screw!) because then you can guide the rotor into the bearing by using a small allen wrench as the shaft has small holes from grinding on both ends.
Hard to explain, but you'll understand once you look at the shaft... then it's real easy and that's also how the process was intended.

That's the best way to place the rotor back to the casing...
