The motherboard is an Asus P4T-E you can get the specs for it here. The motherboard is new and never used still in box and all wrappings. The R/C airplane has been built never flown. it does come with a .40 motor that is new and hasn't been started, so it will need to be broken in. It however does not come with a 4 chan system but I will leave in the 4 servos (futaba). Any questions, or if you want pics I will post them up if you all show some intrest in either. E-mail me for questions, or PM or reply or msn me, or AIM what ever you feel you need to do to get ahold of me.
