Unhappy need help with novak brushless

hi, yesterday i received my brand new super sport novak brushless, i just set it up, now i try it and the bearing that is on the end where the shaft comes out is getting loose and slides back into the cassing.
i opened the motor and took the shaft out, now on the other end of the shaft (the rear end) there is a metal ring that prevent the bearing from coming loose.
on the front end of the motor there is no ring to prevent the bearing from coming loose.
an someone that has a novak brushless confirm that novak forgot to put that infamous ring when they assembled it leaving a 1/4" to 3/8" gap between the bearing and magnet?
here's a picture of the open motor showing the back ring and no ring on the front end.

Have a brushless motor also from Novak.

Took the front endbell of my own unit when I first got it.

And yes there was a metal ring on front also, same as the back might be a different length though.



Warning with the Novak Brush motor do not run car in the air, then put the brakes quickly on will cause something in unit to blow. Couple people in our club do this and their brushless motors will run no longer properly.

Would guess so, good thing you have not had a chance to run it and maybe make the mistake others have made with their own units.

So just stay away from brakes unless it is on the track.

Hello Everyone, I believe ELK has called us already and is sending the system in. If not, you can and we'll get it taken care of. I'm not sure how that could have happened. We run all the motors 3 different times on 3 different testers before they are packaged. I'm stumped.

As for the braking issue. I will take that up with engineering to see what they say. I'm pretty sure the voltage spike from the brakes is damaging the ESC. I've watched these motor run on a "Scope" and they brakes offer a HUGE spike compared to other R/C applications or equipment configuration. Your recommendation for only using brakes on the track is probably a good idea.

You can email me at anytime for Novak or any R/C related question. We're glad to help and give you the correct answers, or at least try to find them.

Thanks,
Charlie Suangka

Hey All,

Charlie's a regular on these boards. He also was killing the competition in the F1RL series last "season."
