the only issues ive had were from running a 2200kv motor on 5s geared for 14/46 which is like 52 and i never even seemed to get that fast. but the lowest i can go is 13 on the pinion before the motor is hitting stuff. but was reading others having problems with the 1521 1y on 6s. so was just making sure ill be ok
