I was there ( At 2002 TOC) to see that 70% edge and all I can say is WOW, The owner says he has a multimillion dollar insurance policy for the thing and cant fly it without droping 5 grand down (yes thats 5 thousand), The prop cost him 7 thousand alone!! 65 hp engine, servos have over 5 ft lbs of tourqe and it weighs about 3 hundred pounds (if memory serves me right) all this and he uses robart hinges 'alot of em'- He has a total of right about 70 thousand into it- heck for that I would of built a full scale (or at least had a good start).
Anyways better quit here, 'Sorry' dont want to get too far off course (the thread) here.
