A review of new products for Scale modelers

There are always new products, goodies, and kits introduced at the Toledo show, and the 1993 show had lots of new scale stuff, too.

Wingmaster (Model CAD)

  • New Windows program from Model CAD, designed by president Bob Webster.
  • A model wing designer that lets you design wing shape at any size, customize airfoils, and print wing layouts, ribs, spars, sheeting thickness, capstrips, taper, and rib locations.
  • Includes a library of 250 airfoil designs (Clark, Curtis, USA, Göttingen, RAF and over 100 Eppler airfoils).
  • Prints to dot-matrix or laser printers; learning curve exists but worthwhile for designers and modifiers.

Sullivan fuel filler valve

  • Simple, affordable fuel filler suitable for scale models; works with glow, gas, or smoke engines.
  • Requires a 5/16-inch mounting hole for surfaces up to 1/2-inch thick.
  • Uses a 3-inch piece of 5/16-inch brass tubing that pushes aside a spring-loaded semicircular valve head and inserts into the fuel tubing, cutting off the line to the carburetor to prevent flooding.
