ERBE with 1515 2200 kv and 18.84259 : 1 total gear reduction(65t spur , 18t pinion) on 6s reaches 50 mph
If I go to 1518 1800kv then to have the same top speed I need to change spur to 54t. In chase of that I get 15.65385 : 1 total gear reduction and that's a way lower.
I can't believe that with gear reduction that low I will get beter runing times
