Default done deal

A club member, who has sewn sails for RC yachts, made the banner from ripstop Dacron, wood dowels, dacron (non-stretch) cord which is presently 30 feet in length. He cut out the club's logo and the letters RCCR and has stitched them to the sailcloth. The entire assembly weighs 9.6 ounces. At 30 mph it flies about 20 feet below the level flight path of the plane. It applies a rather 'large' drag force, and a large amount of flutter may cause damage to the banner. Any member may fly the banner. The towing point should be on the bottom of the plane very near the CG point. It is advised to have a controlled tow release to permit dropping the banner before landing.

The GP Kadet Senior ARF with a Saito 80 does a good tow.

(The December 1977 AMA Model Aviation article about how to fly signs was useful. It's on line in the members only archives.)
