Does anyone know if the old novak 5800 is compatible with stock or 13.5 racing when cut on the sportsman mode? This weekend there was a guy at the track with a smoking fast ride that was using the 5800 and he said it was on the sportsman mode. I am not familiar with the esc and motor, but I am running a 13.5 geared 72/30 and he was smoking me down the straight. I dont want to claim he's cheating untill I get some more info. Thanks for any help guys.

from what ive heard, the 5800 is more or less a 10.5, the sportman mode just slows it down a little when taking off

5800 is closer to a 8.5 motor. 4300 is the 10.5. you got smoked because that is a much faster motor

It' simple if you where running in 13.5 class and he was running a old ss 5800 pro thats an 8.5 not legal for 13.5 even in sportsman mode I would he was bending the rules big time

Yea, the 5800 orginially had the bonded rotor which has weak magnets comparied to the sindered one we now run, but it is still an 8.5 and could have been updated with a new rotor and endbell. Bending would be a very kind term for running that motor.

I think there is still info on the TeamNovak.com web site that shows the motor ratings.

Using the old rating or id system...(which was kV rating)

21.5 = 1800
17.5 = 2200
13.5 = 3300
10.5 = 4300
.
.
.
3.5 = 10,500

and so on...

Thanks alot for the info you guys. I dont want to piss anyone off, but it was a slaughter. He was running 6.4s and we were all about 6.7 and 6.8s, but he cant drive the truck. I am going to talk with him this weekend.

Thats the thing if you cant drive it the biggest motor wont help you win. So why cheat?

Our first brushless motors were the 4300 and 5800. These numbers "roughly" corresponded to the Kv ratings. As mentioned above, they had bonded rotors; but we make parts available to convert old motors into the current configurations with the addition of the upgrade kits and sintered magnet rotors.

Now that we designate our motors by motor winds (turns), the 4300 is a 10.5 T and the 5800 is an 8.5 T.
