now the exi 250 uses the same electronics as the trex 250 so you can see what the pro ppl have on their trex 250.

you'll need micro servo 3 for the cyclic and one for the tail. you can use our gy48V and that will do it. for motor you can get them here: http://www.xheli.com/200sibrmo.html

you'll need 11.1v 800mah 30C lipo for the heli.
