these are seriously awesome, but a couple of questions:

does the spring powered flipper auto retract
can the spring powered fliper be made remote control (from looking at it i think it can but im not sure)
with a bit of beefing up , could these be faught as feather weights
how powerful is the spring flipper ( could it flip a FW)

a vid would great

i was gona build another crappy feather weight , but i might just get one of these instead

edit: sorry just saw the links to the you tube vids :P
