RE: zagi xt extreme speed
my friend put one of those in his zagi it is real fast just make sure you got a battery that can handle it. good luck. i put the 2 motors in a 60, with the two motors its faster than the one 700w. max amps has some good lipos.
my first flight with the new bird was today and it was great. we used alot of carbon fibre reinforcement. still havent hit full throttle on this one yet. i hope to get video up on you tube.
