RE: Vampire
Wayne,
That makes a lot of sense ! The Vamp looked a little too nice . It's hard to get documentation on the correct "Bat Nose" . So far there are the two that I've shown but I also came across some documentation at the Langly museum that looks different again. I guess if you wanted to enter scale competition you could just pick an existing aircraft , such as the one near you. Even if there never was one like that in actual service , it is an actual aircraft . I don't know about Princeton . Sounds fun though !
Jon,
I'm probably being too picky because I'm not likely to compete either. The inaccuracies I discovered so far involve the bottom of the rudder not having a curved line on the rounded vertical stab and some issues with the tailboom. Again I have to say that I don't have the plans in front of me so I'm going from memory. I believe the Vamp had some positive incidence and the plan is 0-0 . I think the airfoil thickness is also different so the way that the boom intersects the wing does not look correct to me when I compare it to 3 views and photos. The depth of the boom looks a little too small and the transition to the top of the wing at the front of the boom is too abrupt . Also, there should be a larger proportion of the boom below the TE of the wing . To fix these problems I'm going to leave the boom depth the same but lower it by 1/4" with respect to the rest of the aircraft. Before I make a final decision I'm going to crawl over a Vamp at a local museum with a measuring tape and camera.
