Default novak brushless and rotors

I am wondering what novak motors come with what rotors. I know there is the older style smooth can with bonded. Those can be upgraded to sintered rotors, and that is evident becouse the endbell changes. But I just read something about 12.3mm and 13mm sintered rotors.

What motors come with the 12.3, do any come with the 13mm. I have a bunch of different motors and if there is a better rotor out there then I want to make sure I have the best possible setup.

The EX series motors: 8.5EX, 10.5 EX, and 13.5EX all come with bonded rotors.

The Velociti and SS Pro Series motors all come with 12.3 mm sintered rotors:

3.5R, 3.5L, 4.5R, 4.5L, 5.5R, 5.5L, 6.5R, 6.5L, 7.5R, 7.5L, 8.5 Pro, 10.5 Pro, and 13.5 Pro.

None of the motors come with a 13.0 mm rotor.

Hi Steve, I've built a direct drive TC. I have an XBR Sport 10.5 with the sintered rotor/lg bearing endbell upgrade. How should I gear it? Thanks, Don

What about the 17.5 motors?

the 13 mm rotor does add more low end grunt and makes it more drivable correct?

I beleive that all motors with out the EX has the 12.3 sintered rotor. The 13 MM rotor is just a tuning option for more torque and more drag brake.

The 12.3 sintered seems to be pretty good for me atleast.

Yeah, sorry about neglecting the 17.5 Pro and 21.5 Pro motors... I believe they will both be shipping with 12.3 mm sintered rotors.

As far as the direct drive TC Gearing goes... I really don't know.. I don't have much experience with that at all! If you have any brushed motor gearing experience start there and gear up a tooth or two every run while monitoring the temperatures... Keep the motor and ESC under 170 degrees F.

Hey,

what is the difference between letters at the end of turns, 3.5R 3.5L and 3.5T?

TIA

The L means its a light motor
Softer accelleration with same top speed and lighter in mass by using smaller diameter wires. If you were racing dirt or slippery pavement I would consider using a "light" motor. Also to consider, would be bonded versus sintered. The bonded will have a softer feel.
