A guy in one of my local clubs has one and I have seen it fly many times. He had some problems with the engine that came with the combo (carb issue that was finally fixed), but the airframe seemed solid. The usual attention that you would give most any ARF, such as sealing down covering, beefing up the gear mounting area, glue joints, upgrade hardware where appropriate, etc. needs to be given, but it makes for a nice airplane from what I saw.
