If you have built Sorcerers or Leading Edges previously, you might want to try building a model from scratch using parts and balsa from Turnertoys Flight Central. Dimensions must satisfy current contest rules (S.O. or other events), but otherwise the basic design from the Sorcerer or Leading Edge can serve as a guide to design concepts and sophisticated construction techniques. You can make the choice to follow the old designs or try something new!

     As important as weight is, we do not believe that the precise weight of each stick of balsa is as critical to success as attention paid to detail, the patience and skill exercised in building, and the hours of practice flying to gain skill and make every possible fine adjustment. The balsa we supply ranges in density from 6 lb/cu.ft (pcu) to 24 pcu in three weight categories.  We suggest you buy enough of this inexpensive material so you can pick and choose from the range of weights you will receive in each bundle: the denser pieces where strength is needed, the lighter pieces elsewhere. Final center-of-gravity balance can be adjusted by wing placement, sanding of parts, and bits of clay. 

     You should, of course, be willing to build your model over as many times as needed until your flight times are clearly competitive. 

     If you have never built a stick & tissue model before, or have not allowed enough time for adjustment and testing, consider starting with the Shoebox R.O.G or Right Flyer, both of which are modifiable and are competitive at the local level. You will gain experience which can be applied to your next event, for which we recommend a Sorcerer. Make sure to plan further ahead next time.

     All our competition kits, including the Super Delta Dart, Shoebox R.O.G., and Right Flyer, are excellent candidates for developing your own winning  combinations. The Super Delta Dart, however, are not really recommended for Science Olympiad  or similar competitions.  They are ideal for beginners who are learning how to assemble, adjust, and fly balsa and tissue kits, and who are just starting to lean about aerodynamics.  The Super Delta Dart is especially easy to work with for younger (8 years +) students, since the components are glued directly to the plans, and it is possible to assemble with a glue stick in addition to a liquid glue. Both can be flown outdoors just for fun on calm (no wind), dry days.      The Shoebox ROG is a good first competitive choice for students with some building and flying experience.  It qualifies for competition, and is a very competitive endurance flyer in its size class if built carefully and adjusted properly. The Right Flyer is a fully competitive choice for longer indoor endurance flights, although a bit heavy for its size. It can be flown outdoors on calm, dry days, and is rugged enough to survive the occasional minor mishap.

     Our Build-N-Fly and Ready-to-Fly models (specifically the G-75 Flying Machine) are also strong fliers, and may be used by beginners to acquire experience in building and flying rubber-powered balsa models. Endurance flying modifications are not included in the directions, but a knowledge of simple aerodynamics allows some productive tinkering. They are not considered contest-winning designs (too heavy, among other things).
