Wow, more great help. I think I will definately spend a gallon or two on the test stand with the engine getting the tuning right. Right now the transition is set as close to perfect as I can get it. I just need to adjust that high end mixture for optimum power and remember to enrichen in flight and se that smoke trail. I was not looking for a screamer of a jet, it will sure be faster than the WW2 warbirds I have been flying. My long didtance goal should the plane see long life is a turbine retro-fit. Wren makes a nice turbine kit with the right amount of thrust and have some input and articles on how to prep the model to withstand the high heat generated by these engines.( I believe one was a pipe-in pipe system that kept the hot inner pipe from contacting and melting the airframe. ) Well see about thatif it comes.
As for the input on the paint, I will use a fuel proof primer coat (Lustercote) before applying my Krylon. Krylon has a god blend which atomizes evenly, dries to a uniform finish and dries fairly quick. I plan to wait 24 hours after applying paint and scuffing it with emory cloth to accept Lusrercote matte clear.
