It seems the lowest KV Scorpion makes in thier 4025 range is 550. For anything lower it has to be the bigger 4035 etc.
The Align 600mx is a similar size and has a version in 510kv.
Is there any motor out there in roughly the same size with a lower kv? I assume it has to do with the diameter and how much torque it can produce at a given size.
I want to do a conversion of a nitro heli with limited gearing options. The other route would be to go 10s but I'd rather do 12s if possible.
