I was just talking about this with my LHS plane guy....

I fly a Power 10 on a 51" foamie that weighs 36 oz...It will hover and pull out but it's not Ballistic like I wanted. He flies the 480 on his Mini-showtime and thinks it has plenty of power with a 2200mah 3S 25C 11.1 volt batt..The mini showtime weighs 26oz normally....I think unless you are looking to blast off, the 480 is better...You might also have to fix the CG with such a heavy motor like the Power10. My Power 10 seems massive compared to the 480 sized motors I have....You have an ESC yet?
