I am ordering some new batts just incase - but spinning the rotor when it is at rest by hand... it is very jerky. Is that normal? I have had a few wee prangs in the past - I am worried that i have done something to it.

Any tips?
New batts is good. Jerky rotor OK. Mine's like that and so is my other brushless KV2500 on Sbach. I believe the term is "cogging". I believe it's the magnets and winding doing their thing.
