Which rotor size is better for 17.5 and 13.5 carpet racing with timing?
Which would be better for no timing?
i have tried 12.5 and 13mm high torque rotors in 10.5 with timed esc and found no gain currant draw is heaps higher lipo 50c 5000 not lasting 4mins in a race temps heaps higher only advantage was is gave the tekin brakes. have not tried 12.3 but would guess it would work better with a higher fdr. stick to the std rotor
