This is a building event. Teams will build and test ahead of time up to 2 rubber powered single prop monoplane(s). A flight log containing at least 6 parameters for at least 10 test flights must be written and turned in at the competition. At the competition, teams will have 8 minutes to complete up to 2 official flights for the maximum time aloft.
Teams MUST bring Safety Spectacles, their plane(s) and flight log. Teams may also bring any materials needed to trim and calibrate their plane(s).
Event Leaders will bring tools necessary to measure and check the planes, and the official scoresheet.
High score wins. Points are earned for seconds aloft. Teams missing part or all of their flight log will be penalized.
Don’t forget your flight log! This is an easy penalty to avoid.
These flights will take place in some sort of gym, either a basketball court or an open arena, depending on where you compete. If you do not have access to a gym, reach out to other competitors at nearby middle or high schools and see if you can share practice time with them.
Balsa wood can be bought at most hobby stores, or in bulk from Tower Hobbies or other online stores
Rubber band motors and winders can be bought at some hobby stores, or from Midwest or other online stores, search for rubber motor or contest rubber. Also, make sure you know the gear ratio of your winder. 1:5, 1:8, and 1:16 are all common, and will affect how many turns you make to achieve the ideal number of winds on your motor. The first number (1) is how many times you turn the crank compared to how many times your motor is turned on the output side (the 2nd number).
