I learned to fly on one of these save your money and build a spad instead the aircore is alot harder to put together than a spad and alot more money, save the money and put it toward the engine and radio. As far a durability the spads take more of a beating then the aircore I destroyed mine buy shoving the stupid power cartridge back and tearing the coro fuselage. The aircore needs lots of power and on a flame out it flys like a shoe.
