Question
Is anything over 32,000 rpm (lets say 76,000) deadly?

Why does prop rpm matter? From what I understand, a small prop spinning at a faster rpm can equal a larger prop spinning at a lower rpm. Is it imperative to keep rpm around 32k? I was wondering because I wanted to put 76k rpm (at 7.4v) to a 15mm prop on a 9 inch boat.

Basically just a mini-z cat with a 1220 (inrunner) with 10300kv.
