Thanks for your help, I’ve decided to go with the turnigy 190kv 6374 and the enertion motor mount that comes with a key… I’m gonna borrow a dremel.
How do we find out efficiency I want to calculate my 192kv sk3 turnigy %

Old thread i know, but as someone else revived it… there is no reason at to grind flats on motor shafts, just use retaining compound, its what its designed for.
