Brewster Buffalo

Unless a control-line scale model has been designed by an expert, thoroughly tested and developed, its builders can lose precious time and money in a wrap- up. This .35 to .64 job delivers results.

The stubby Brewster fighter of WW2 is an interesting scale model that always attracts attention when flown. The scale of 1" equals 1', results in a wingspan of 35". Two K & B AS-powered test models were rushed to completion the night before leaving for the 1959 Nationals. Even though they were not ready for competition (the new engines were not broken-in) one was entered officially. It was flown to second-place in the windy Nationals Sr. Carrier Event by Idaho Air Youth Champion, Doug Wenzel. The model weighs 46 ounces, ready to fly, and can .be powered with engines from .35 through .64. A good .35 would give sufficient speed for smooth flights, although several ounces of ballast would be required inside the front edge of the cowl ring to obtain the safe, tested CC position. For carrier events a .60-size engine would be the logical choice. The additional weight of a .60 would eliminate the need for nose ballast (this airplane has a short nose moment), thus, the overall weight would not be increased enough to effect the low-speed figure. A glow-plugged Orwick .64 would be a natural for mounting radically to the firewall. The Anderson Spitfire or Enya .60 could be installed, as well as the old Atwood A9's and 51's, although the idling qualities of the latter two engines are not known to this writer. Installation of the McCoy .60 or Dooling .61 could be made if the 3/16" plywood nose crutch and firewall were modified to accommodate beam motor mounts; the fuel tank then can be mounted under the wing center section, this being a practical tank position for engines with rear needle-valve locations. Performance figures are steadily increasing with more break-in time on the K & B .45 powered test models; thus far, high speeds are slightly over 80 mph, using an 11 x 8 Power propeller. It is important that the K & B AS receive four or more hours running-in time on the test block before (I being leaned out to maximum power output. Low-speed flight and the carrier deck landing-approach, present no problems since control with the J. Roherts
