Super Delta Dart A good introduction to building competition kits for kids as young as 7 with hands-on adult help. Long flight duration, strong framing, movable / removable wing for center of gravity experiments. May be flown outdoors on calm, dry days. The Super Delta Dart has a unique, easy method of construction: The plan or diagram is also the tissue covering, so balsa pieces may be glued right to the plan and the tissue trimmed to fit. Makes cutting accurate balsa pieces almost fool-proof! Features bilingual (English/Spanish) instructions. 21.5" Wingspan, 15" overall length, motor is 12" loop of .0625 rubber. Use Turnertoys #378 motors for replacement.
