I think what we don't know is the difference in "H" and "R" servos. I do believe that there are two different servos, some being race oriented. My bet is that there is an '"R" for race servo of some larger diameter that delivers stronger shifts. I think these are available from the after-market. My belief is that these would be the "R" servos and that the "H'" servos would be the stock ones. This is all complete conjecture.
