I used it on my mini AMX. I removed the 5 blade and used this one. It needed some cutting up to the lip to fit the stock motor and to drill the fan whole with a 2mm drill. other than that it fitted VERY WELL..
I used it on 4S with stock motor and ESC. THE PLANE was a BLAST :) ballistic speeds and very safe with 4S packs.. hit more than 100mph downwind very dureble plastic with no flexing and no rubbing o nthe shroud I'm very happy with it
