i picked on up from the lhs, it's got a axi2808/24 with a pheniox 35 ecs. i was trying a thunder power 2100 mh lipo but the esc would cut the motor off to soon. reprogramed the esc and it worked alot better. do have 2 tanic battery packs on the way both are 2500mh should get alot better flight times. i called castle creations and they said that the tanic batteries are alot better battery for the money. can't wait to get back out with this plane....
