I smoked one motor this year in 17.5 Spec at our local track. Missed the gear by one tooth. Think it was more of a crappy motor than anything though (small name brand I was trying out).
I have not seen very many motors melt down in the past few years either and think it was early on in BL when guys didnt know how to gear them that there were issues. Mike Haynes had one go at the birds this year in Super stock TC but it was a fluke where he was boosting it VERY high he said.
I think its a minor thing now that some guys are using as excuses and blowing it out of proportion because they are misinformed for the most part.

it was a big thing back in the day. guys were complaining that the car would just shut off. most want a way to stop it from happening and that is when the blue wire came up and most were cutting the wire so they could finish races. especially guys running outdoors in the hotter climates

You probably can get your slightly overheated motors to work like new again with new rotors.
I also have been at several series races with spec 17.5 classes, where there were 20+ 17.5 spec cars, and i have yet to see a motor go up. I honestly think this is not that big a problem.
I do remember guys smoking motors in the early days of BL racing, but a lot of that seemed to be due to LRP TC spec Escs that people didn't realize had timing advance. I never melted a motor with a GTB.

Oval racers are extremely hard on motors (stators/rotors)---especially when using timing/boost controllers. We just released a line of epoxied replacement wound stators (for the Ballistic 540s) to mitigate this potential stator damage.

So you added an additional insulator to the windings and that's gonna help them not blow up from heat? Really?

We removed the temp sensor from the GTBs many years ago; racers were cutting the blue sensor wire anyway (and complaining...) so we disabled it.

You've breach new ground in cluelessness.....
Epoxy is NEVER going to reduce heat in a motor like that. Its always gonna add it. Epoxy is a piss poor conductor of heat, so all its gonna do is trap it in there.......especially if there is any air bubbles, which there probably are as I doubt you are using VPI to weed it out.....
There is a reason slot car guys try to get as LITTLE epoxy on the motors as possible....they do everything they can to remove the excess, as all it does it trap in heat....
The main reason epoxy is used in brushed motors is to prevent the windings from moving.....last I checked, they don't move much on a stator......

Here is a much better place to criticize Novak motors.

Awesome......it's amazing all the years trinity was bashed for its adversting, yet novak can post this....
"The Ballistic Hand Wound Stator is dipped in a special motor winding epoxy and then oven-cured for several hours. Once the epoxy is cured, it prevents the wires in the stator from moving or rubbing against the laminations and other wires in extreme conditions. Preventing this unwanted contact avoids shorts in the motor coils which can lead to premature failure. The epoxy also helps transfer heat from the wires to the lamination, helping motor operation at higher power levels.
All around, the epoxy coating improves the reliability of Novak’s already high-quality stators and provides extreme vibration resistance. It also prevents illegal rewinding of the stator. "
If your wires are moving in a stationary setting, well thats some PISS poor winding. Even then, thats not a heat issue, thats a short....a short from poor quality.
Copper is a supeirior heat conductor to steel. Its going to draw the heat from the laminations if anything and dissipate it on its own.
So while you are preventing wires from moving, which they should not be in the first place....the epoxy will do nothing to help heat transfer or the thermal properties, it will make them worse, especially if you are just dipping and baking them.....
Now, they do prevent cheating some.....so I'll give ya that.....but I guess any monkey can buy some epoxy....rewind his stator and say hey look, its still got epoxy on it from novak! Sure is gonna be fun the first time someone has to tear one down to count the winds too.....
Stick to giving out the tech number or email, as you are clueless on how stuff works.....
