My front motor (DR8) bearing lasted 1 battery. Ever since, motor bearings get ceramic ones and I make the rig more sand proof. Never had a problem since .

No I didn't open the motor. Once it ran fine after removing the spur I put it back together. This is my first brushless. So I didn't know to pull it apart. I will have to look up some videos.Did you open the motor? Clean the BB's and all with an Electrical contact spray, (CRC automotive brand ) and Relube the BB's while you were in there. Do this regularly when you do pull the power module. Need to visibly examine the condition of the armature also.
When you powered the motor while it was out, was it silent and smooth running, little to no vibrations felt?
A motor will run under no load even though the BB's are worn.
It should just hum and be fairly silent. A properly running motor is very quiet.
I test my BLX motors on my Motor Analyzer. And when I do a Decibel Motor Noise Test, a proper New motor will show below 95db most of the time. Varies by motor brand.
That's my reference. As BB's wear out, Vibration increases, because the armature and BB's don't spin true, so decibels increase, a sign of needing new BB's. Or even the Armature shafts are galled out and worn. Sometimes even New BB's may not help in this case. The armature is now worn. Can still run it this way up to some point. Neglecting maintenance can cause this. Ultimately needing a new motor. New Armatures are not available for most motors.
EDITED.
I'm looking into bearings now. Are Stainless or ceramic better? Any advice on more sandproofing?My front motor (DR8) bearing lasted 1 battery. Ever since, motor bearings get ceramic ones and I make the rig more sand proof. Never had a problem since .
As mentioned stock beatings are usually pretty bad when it comes in handling heat and high rpm’s for longer periods if time. And we are all pushing our cars to run faster and longer.I'm looking into bearings now. Are Stainless or ceramic better? Any advice on more sandproofing?
It does sound like your motor. You could try to warranty it through horizon. Or If you don’t want to try fixing it you can pick up a stock one off Jenny’s for $50 I think. Or better, get a surpass 3670 for $30-35, 3050 kv I imagine. Then get a ‘non safe d pinion’ for 5 bucks.Well haven't messed with this thing in a while. Due to just having a baby. Charged up the batteries for some play time and it's right back like it was. Cogging trying to start up and not going. Not even with a push would it go. Kinda aggravated with it at the moment
Yes, of course it will run with the BLX 100. No problem at all.It does sound like your motor. You could try to warranty it through horizon.

Will the 3670 surpass run off the blx 100esc? I have a 3670, 2850kv with 130 esc and 18t pinion in my granite and vorteks. It’s perfect for me, runs cool and strong. But I never tried it with a blx 100 esc…
Ok thanks man.Yes, of course it will run with the BLX 100. No problem at all.
Never tried a 6 pole motor. Don't know what the performance difference between a 6 and 4 pole motor would be. Maybe the 6 pole pulls more amps than the 4 pole motors and that might be why it didn't run so great on the 100a ESC. But I'm just guessing. Maybe someone else knows the answer.Ok thanks man.
The reason I was wondering is when I hooked up a 6 pole, 2800 KV 3660 motor to a BLX 100 it ran like crap. When I switched to a 130amp ESC it ran beautifully. So maybe maybe the blx100, which is kinda old (the one Kusher gave me a while back) is going out? You know far more about this technical stuff then I do
No clue either. I got it a while back… impulse buy lol.Never tried a 6 pole motor. Don't know what the performance difference between a 6 and 4 pole motor would be.
