Hi Tim Sent me the ESC capacity its 30 amps,so cant see a problem fitting 480 motors.also found the sound maximum its 10w and 8 ohms.So the speaker i have is spot on its max 10w(normal8 w )and is 8 ohms,so shouldnt have a problem with that .Now just need to find out how to do the different recoil units,

regards pete

P.S like the way you done the 45 degree defence,if you extend the top a little it may well give you angle defence.
