ORCA Rotors

[JBL]

Are Orca rotors similar to any other brand such as LRP. I find the ORCA RX2 motor quite torquey and i'm thinking about changing the rotor?

From my research, RX2 use a 12.5mm rotor on modified and 12.3mm on 10.5. Axle diameter is bigger on stock so even less magnet.

Quite torquey for sure, I love them. Still most new motors uses 13mm rotors (Tekin, Viper for example) so more torque (and more heat). I will try some Orca 13mm rotor soon for the fun of it (ordered some from them), still I think I don't need anything more on my RX2's. Orca did try 13mm but settled for the actual one for a good balance between torque, heat and smoothness.

You could also try the stock silver rotor, 12.3mm. Less torque, only try this one on a 10.5.


This brand rocks

Based on what i've seen of the motor I would suspect that GM and Speed Passion rotors would fit.
