SO, you want to build a Stunt plane that has dihedral in the wing? That Spitfire or Bearcat that you've always admired is just itching to jump off the drawing board onto your workbench. "But, how do I set up the dihedral and the leadouts so that it doesn't fly crooked?" Let's take a look at the subject. Assisting in this article is Scott Bair, Atlanta, GA, a research engineer who, over the past four years, has built six Stunt planes with dihedral in the wing. In addition to the use of dihedral in his planes, Scott uses unique building methods which include a Free Flight-like fuselage structure of longerons and 1/8-in. bulkheads covered with paper, which gives a strong yet featherweight finished result. In the future, we will see some of his masterful building projects that result in 46 oz. airplanes with 670 sq. in. of wing area!

CAMOUFLAGE. Or, how to cover up your mistakes. Or, how to hide some of the "bad spots" on an old plane. Let's suppose it's June 1, and you haven't even begun a new airplane for the summer. You have last year's 12-pointer hanging on the wall; the wing is straight, you have a good engine, you know how to fly this plane; but, it'll be lucky to get 10 points at the Nationals, and even your best friends will keep saying, "Build something new, you can't fly that old wreck again!" Well, maybe you can. You could quite possibly repaint the entire plane, which entails very liberal use of alcohol and K2R Spot Lifter to get all the fuel off the plane and make the surface ready to take paint. This would also require sanding most of the old finish off and probably making spot repairs in some areas, for instance: fillets, around the cowling, some dings in the wings, around the canopy, and perhaps the wing tips. To give the impression that you have a new plane, you might try to change the overall color; remember, reds and blues are very difficult to spray over. You may also have to switch to one of the epoxy-type paints in order to get good adhesion to the old surfaces.

HERE'S MORE on control line handles as a follow-up to the column on the building of the "Paul-Robbert Super Handle" (April 1983 in Model Aviation). Firstly, Lew McFarland will shortly be marketing the George Aldrich handle through his X-Cell Hobby Shop, Eastland Shopping Center, Lexington, KY 40505. This handle was very lightweight and adjustable for inside/outside turning equivalence. Secondly, I received a very detailed letter from Windy Urtnowski regarding some flying experiments with handles. Excerpts are as follows. (Keep in mind that Windy flies with many of the New Jersey crowd including Glen Meador, Lou Dudka, Lou Woolgast, Bob Hunt, Doug Stout, and Bill Simons-and this group is never at a loss for words for advice, questions, encouragement, experimentation, and lots of good old bench-flying!)

U.S. CL AEROBATICS TEAM. The 1983 FAI team tryouts was held once again over the Labor Day weekend, which is now traditional, and the flying was held in Dayton, OH which has hosted many FAI tryouts. Two of the winners were repeat members of the team. And, for the sixth time, Keith Trostle was the Event Director, which probably sets a record for the number of consecutive times as the ED. Bob Baron (Claremont, CA) came out the overall winner, as he led all the way from the first round on Saturday. He will be making his second appearance in the World Championships, which will be held in the United States next summer. The fliers flew three rounds on the first day, adding the two highest scores to the two highest of three rounds on Sunday for their overall scores. Eight-time team member Bill Werwage (and World Champion in 1970 and 1972) finished second in the tryouts, with a score of 3983.25 to Baron's 4102.50.

Readers may be wondering what has happened to our regular CL Aerobatics Contributing Editor, Wynn Paul. He's still alive and well! We have been experiencing a mysterious problem with the U.S. Postal Service: Wynn's columns have been lost in the mail for the past two months! By the time it has been realized what has happened, it has been too late (too close to our publication deadline) to do anything about the situation. So, as insurance that CL Aerobatics would be covered this month, we've asked Lou Dudka to write a column.
