36 is about what I have my RC8T geared for with a 1515 2.5D on 5s, with no figure for tire ballooning as well. I don't think it's to low by any means, when I geared up I actually ran slower times. For me 50/15 or 50/14 seems to be perfect on the track, with 43/10 diffs
I guess issue here is RPM on motor, not actual speed of vehicle.
Well isn't the 2200kv motor made for 6s use? Obviously it isn't ideal because 2200kvx25.2= 55k RPMS. How come they advertise the crap out of the ERBE and FLux running on 6s with the same motor.
