KV…. It just doesn’t make sense! 😅

TP is serious stuff.
I saw some reviews say that, Steve Neu/ Castle make more efficient motors. 90+%

Try getting your hands on a blueprinted Neu motor. Wish I could.

Castle motors in my mind are to blame for so much of the motor choice KV confusion.

Each KV option from Castle is also a different motor size. (exception of the 2028 has 1100kv and 800kv) You are never accurately comparing one KV to another KV in that scenario as the can is longer or larger diameter etc....

Take TP Power for example they offer something like 12 KV options for 1 motor can size. Then they have the CM and SCM rotors that are good for 75k+ rpms. I love TP Power

Castle also has the 1717-1260 and 1717-1650 but otherwise I understand what you mean.

This guy has a lot to say about this topic (and rc in general).
