Hey guys something just happend when i turned on my rc.
I seen sparks and some smoke from the GTB and the car was acting erratic so i immediately disconnected the battery. The GTB was a bit warm as well as the battery and some wires, battery just came off charge.
I have a Spectrum GTB Novak 4.5R and a Team Orion 4800Lipo.
Its only been run like 3 times.
Any help is appreciated.

Jeff and Mike talking brushless on the couch. Check out the new segment on http://www.rctvlive.com called 'after hours'. Enjoy!

I would recommend the warranty form, as the formal warranty is 120 days. Make sure you fill it out completely.
However I notice you're in Australia. I think you may deal through a more local distributor. Try email to [email protected] or [email protected]. Although they always respond, they've had trouble with their email filters... If you don't hear back in a day or the email bounces, try posting again here. Meanwhile I expect Steve or Charlie will post here where to send it.
Turnaround is about a week, plus shipping on each end.
Novak has fantastic customer support. They are definitely excellent to work with when you have a problem.

Don't worry. Your not alone! There were two locally that went the same weekend. Both only ran like two times. I have a great pic of mine smoking. Most smoke we have seen from a RC car at the track yet. Novak will remedy the issue with yours and you will be good to go. On a good note. The two Novak's only smoked, but the Tekin G-11 actually caught fire!!

GTB + 4.5R thermal shutdown
Hi, I'm running a Losi JRX-S (1.83 IR), GTB with a 4.5R motor. My problem is thermal shutdown.
Here's what I noticed in different runs:
GTB + 4.5R with non-sintered rotor
used FDR of 10.2 - thermal shutdown after 5 minutes and 1 lap (23 secs)
used FDR of 9.76 - thermal shutdown, did not finish the 5 mins. heat
GTB + 4.5R with sintered rotor
used FDR of 10.2 - thermal shutdown after 5 minutes + 2 lap
used FDR of 9.76 - thermal shutdown after 5 minutes + 1 lap
used FDR of 9.37 - did not continue feeling I might be overgeared as it seems acceleration is mushy and car slowed down after 2-3 laps
temperature measurement ranged for the motor from 68-81 degC after shutdown, ESC is about 48-55degC (measured after each test run)
Am I undergeared with the above set-up? Also with the sintered rotor, I notice sometimes there is a point after braking, the motor wont run (cogged?).
Does undergearing could also cause the brushless system to overheat?
One more thing, I think my radio is set to 50/50 electronic thown and not the 70/30 recommended, will this have anything to do with the overheating/shutdowns???
Many thanks to all for the help. Regards..

the 13.5 without sintered rotor will thermal at approx 200 F
Everytime you thermal the motor the rotor gets weaker and will thermal again at a reduced tempreture (for example 190F)
so try to be cautious or better yet get a sintered rotor
if the track does not allow that, then be cautious and ask your fellow club members what ratio they are using.
