SPAD
Simple Plastic Airplane Design
After building high winged airplanes for several months, we agreed that we
needed something a bit sleeker that also did away with rubber bands. That
inspiration led us to the development of the Demon. This plane flies like a Scat
Cat! Very solid flight characteristics with no bad habits and it looks so good on
the ground and in the air!

  • Page 2: Tail Feathers

    Dowel scraps can be used in the corrugations at the attach points to prevent Coroplast® crush. 6. Optional panel edging can be added to the stab leading edges for dress up and to keep dirt & fuel out if desired. file:///C|/Users/Frank/Documents/Demon/dem2.html[6/14/2011 4:30:56 PM]...
  • Page 3: Landing Gear

    REAR wing mount holes (see drawing #7). Use the same drill sizes you used when you mounted the tail feathers. Using two ¾†#6 sheet metal screws, mount the wing to the fuselage. NOTE: The landing gear will retain the forward edge of the wing. Landing Gear: file:///C|/Users/Frank/Documents/Demon/dem2.html[6/14/2011 4:30:56 PM]...

  • Page 6 9. Your SPAD will remain stable and hang on the elevator beautifully during slow flight and landing. With it's long wing chord, the SPAD will fly like a kite against a 10 mph+ wind! Keep in mind that the SPAD has quite a high drag front profile, and will slow down fairly quickly when throttled back or dead stick.
