Leopard 3674 2200 KV ?

Hi all i have ran a Leopard 3674 2200 KV 4 pole motor in my J.A.E. .21 i have run on 4s for several seasons the other day while turning the motor by hand i noticed that there was very little cogging resitance compared to my new Leopard 4074 1650 KV motor .Turning the used 2200 KV motor seamed more like the old 2 pole Feigo motors. Is this normal for a 4 pole motor as it is run for 3 + seasons? I guess i will have to wait till spring and put the gps in the rigger to see if it still runs 65 mph + ! Regards Andris Golts.
