Tangerine. Simple rubber sport trainer model.
Quote: "This really fine performing but simplified stick and tissue model should take the Tenderfoot about a week of evening work. It is ideal for a club project activity. Tangerine, by Stephen C Lovely..
If you want a rubber-powered free flight that has good performance and is simple to build, then Tangerine is for you! For five or six nights' work and about $2.50 worth of materials, you can watch your very own Tangerine point its nose at the sky and drift down the breeze.
Start with the wing first, since it takes longer to build than the tail or the fuselage. While the glue on one piece is drying, you can start working on the others. By starting on the tail when the wing is set aside to dry, you will avoid sitting around waiting for the glue to dry and can start flying that much sooner.
Don't skimp on the drying time - it can lead to joints that don't hold and flying surfaces that are warped. Joints that don't hold have to be glued over again and warped surfaces can lead to problems at the flying field.
With Tangerine you won't have to travel far because all you need on a calm day is a football field.
Construction. Start the wing by cutting out the ribs. Make a template for the ribs from tin can stock, 1/16 plywood, or some other material that is easy to shape yet strong enough to cut around. Place the completed template on the balsa sheet and use as a guide for your knife when cutting ribs.
When the ribs are all cut out, cover the plans with waxed paper or Saran Wrap so the glue doesn't stick to them. Pin the 1/4 x 1/16 balsa trailing edge to the plan. Without gluing, put the ribs, the 1/8 square leading edge, and the 1/16 square spar into position. Use the dihedral guides to establish the proper angle on the ribs as shown..."
