Thanks dubd. That is exactly the kind of info I'm looking for. Are your stars and bars colors correct ? Do you feel that the diehedral is correct ? I am also very interested in how the wings are attached and how much of a pain is it to put together and take apart ? Do all three gear run off of one retract valve ? How are your doors sequenced ? Where did you move the door cylinder mounting point to ? Are the flight control surfaces counter balanced (mass balanced) . If done properly counter balancing should eliminate most if not all control surface flutter. I like lots of speed and performance so I figured a 200 size engine would be the minimum I would want. I assume they do not run a fully enclosed engine bypass ? A fully enclosed bypass might depressurize the fues and allow the doors to stay closed better.
