Well its hard to say for sure that it would, but it should. Rotors will lose strength over time no matter what. Your settings look right on your esc. although if you wanted you could add some boost to the tekin. say 4500 start....20,000 stop try adding 20degrees and check temps. My brother runs the exact same setup in his sc10 mmp/tekin 13.5...he bought the motor new and he has been trying to get the speed out of it and has had lots of trouble. He has tried all kinds of gearing and timing with his mmp and it just doesnt seem to be much faster than my blinky D3 17.5 with max can timing. I seem to think its just his speed controller either bad or just not as good as my Tekin rs that i run...
