Great video. I bet the MM was scorching after that run with all the hard braking you do...

Actually not at all. It was about ~120*, and the caps were the hottest part, at about ~135*. And the motor was around ~130*

Thanks guys!

I finally got my Protek LiPo back today. Alot sooner than I thought too.

Anyway, I had one of them on the balancer, and I didn't know what the balancer should be doing, like what lights should be on and all that, so I was telling Takedown on AIM what it was doing.... and he is like "Thats not good, thats an error, one of your cells is messed up....." Well I make a video, and show him..... and he goes "I forgot about the green light... watched the video, bad news...." and right then this horrible feeling of failure came over me, and then he comes back with "Its working

" And then I was extremely happy yet I wanted to punch him in the face for scaring me and making me feel like a failed......

Anyway, thanks for your help Ryan, getting me to finally gone LiPo.

I just have to get used to waiting for the packs to balance and the fact that it takes my charger FOREVER to do the voltage ramping or whatever it does for LiPo's. I come from all Ni-MH's so I am used to charge and run.

I will get a video of some speed runs with this monster tomorrow most likely.

No problem chris. That one error was an epic error by me. I completely forgot about the blinking green quick balance light. I thought you were talking about the error light.

But yes, you helped some.

I have some bad, bad news........

Ran it for the first time on LiPo this morning. Just bashing around, no speed runs or anything like that, checked the temps of the motor after about 7 minutes of running, around 130. Well about a minute after I checked the temp, I noticed smoke coming from the motor..... and more and more started coming from the motor. Checked the temp while the smoke was coming out of the motor, and my temp gun just told me error, and wouldnt work at all, so I couldnt get the temp of it when it smoked.......... And yes, I stopped as soon as I noticed the smoke coming from the motor. And now, when I try to roll the truck while everything is off, there isnt nearly as much resistance from the motor as there used to be (as in the magnets keeping it from turning). And after it smoked, before I shut it off, when I would give it throttle it wouldnt move at all really, and when I would turn the MM off then back on, the beeping sound was very weak and faint.

But what is so odd about this is that I have run it about 15 times or so on 12 NiMH cells with no issue at all. Temps were good, stayed at around 130, and performance was great. Then, the first run on LiPo, started out with amazing torque, temps nice and low, normal, where they should be, and then suddenly, smoking. And this Align 600XL motor is rated for up to 6S, so I dont really think that its first run on LiPo, and only 4S at that, would have fried it. It's possible, but seems unlikely. I just don't understand why this motor would suddenly start smoking like this after having such cool temps after 7 minutes of running on 4S LiPo and working fine with great cool temps with 12 cells NiMH.

So why did this thing fry? Seems like the magnets have lost their power (as I stated above), seems also like the stator could have fried, maybe the windings? But the smoke was only coming from the holes/vents around the front of the motor. So why did this thing smoke/die/fry?
