Only used a few times . 4 Battery charger [ 110 v. or 4 d cells ] Single charger uses 4 AA batteries Extra repair parts plus 5 lipo batteries . You will need 4 AA for the transmitter and 4 for the single battery charger if you use it .Takes some practice but lots of fun once you get it trimmed correctly and get some practice in , READ the manual first .Need a totally calm day to fly outside . I flew it mainly indoors .
