Is it thermaling from temp? And what temp?
Is it possible that the speed control is the problem?
Was it temped? Bizzare.

Rugdog a racer at our track was able to do one. I'm not sure what brand or enen if it was 4800? But it didnt have a case, and it was shrink wrapped.the wire connection was coming out by the rear diff, with a deans plug.
Sorry no picture but any things possible.

A safe range is 150 to 170. But 120 to 130 seems good on our track size.
120 seems to be really good. I think Chalie hit it pretty good, with the sintered rotor its hard to get it real hot even if over geared ,the track size is the factor. I havent hit over about 135 with my 4300 with a sintered rotor.
He mentioned the stater is getting hotter than the rotor. Be carefull if you hit 150 with a sintered rotor your probably over working the can.
And goodbye effiicency

Max Amps 4000's will fit. You just need to remove the shrink wrap, reroute the wire to come out the top instead of the side and then re-shrinkrap it.

I havent been able to get mine that hot. I guess I dont have enough room for the teeth. And I think you have seen our track.
My best runs where at 120 to 130.
And honestly I have tried to abuse these motors.
Not my lipo's though.
To bad we cant compare side by side at the track.

At 150 did it seem slugish, sounds like it didnt hurt a thing if laps didnt change what about battery voltage did it drain more?

I'm running the 4300 with foams, and 4800 lipos, the consistancy of the lipos can some times hide the fade of being over geared. Are you running rubber I thought maybe that is the temp differance.I noticed 2 teeth to be 20 degrees hotter. I have noticed about 4 degrees per tooth on my motor.
Looks like yours took 10 degree jump per tooth.

yah I run low bite rubber so the motor has to work more than high bite I will see how it is at the novak/high bite!

Good luck at the novak, shake Mr. Novaks hand for racer X.
I would custom set the speedo for smoother bttom end if the tracktion is real high. That will keep the temp down and improve efficency.

2 questions regarding this info on your website:

1) Will the measurements stay as posted regardless of rotors (e.g. a 4300 upgraded to a sintered rotor)

2) Can the motor be left in the car (e.g. if a 'post tech' was to be done of top 3 cars)

I'm assuming the answers to both is yes ...but don't like a assume

Hey custom I found less grunt coming out of the turns seemed faster, or smoother deffinitly helps the diff. I think the drive freq would be around 6 or 7. I 'll check to.
