Hi there, sorry to hear that - sounds like you bought a newer version yes, from version AL 3.0 - this has the space of 68cm, the current spacing too. The older version, like your 90cm, is 60mm. So there should be a fair amount of used or end of season offers on the Fanatic Fuselages on the market, just make sure you get one of the new Pocket fuselages with the correct spacing then. Here you should choose the AL68 or AL78 fuselages, these will definitely fit the AL 3.0.
