Well, I sure like mine anyway. One flaw - the fuel is eating the covering after 50 flights. Other than that it has been great. Went together extra easy, instructions clear, everything straight, and I used all the stuff in the box - clevis and all, and no problems in second summer of operations other than the darn covering shatters if you drop a screwdriver on it (did I really do that?) and as I said, fuel eats it. Oh ya, and the GMS 40 won't shut off - idles great, but even with mods I can't do anything to shut it off except pinch the fuel line or put a finger over the muff. But I think anybody who wants a plane that is a step up from basic trainer should consider the Vmar Challenger - I really like mine after two seasons.
