Good motor
I dropped the 2250kV 4074 as an upgrade in my sonicwake v2. Hits mid 60s mph now with this motor and a 4519 prop on 6S.

Great for the money
Been using these in my 3d printed jet boats, they fit great, and work extremely well for the price. Seem to be fairly durable and produce great speed.

Poorly round, 30% empty can.
This motor has the loosest windings you can imagine. There's at least 20 mm of can length that has no rotor engagement and no stator length. There's so much extra winding that's doing nothing but generating heat. It's closer to a 4060 then a 4074, but it's going to use power like a 4074.
