Welcome Science Olympiad B-division competitors!
To start off, we would like you to know that YOU are responsible for making sure that your aircraft/vehicle that you bring to the competition conforms to the rules and regulations. So before you pick an aircraft or vehicle, make sure that its dimensions are legal with this year's competition rules.
Keep in mind that you can easily reduce wingspan by cutting down a few sticks. So you could buy a plane with a wingspan that exceeds 40 cm and cut down the center and/or wing tip leading and trailing edges until the wingspan is equal or less than 40 cm.
If you have no experience, start with the CF-1. If you have experience and you are flying in the 40 second zone, the CF-3, or the AF-22, 23, 24 are for you.
If your flights are consistently over 60 seconds, you are ready for the AF-31 Shrike and even the brand new AF-16 Falcon, which has even lower wing loading than the AF-31 Shrike.
B-division
For 2010 the rules state that the aircraft cannot have a wing span greater than 40cm, but there is no limit on the wing chord. There is a bonus at state and nationals if you use extremely small chord lengths. After testing several aircraft we have concluded that a 7grs aircraft with a larger chord will do much longer flight times given a 20cm prop and a 1.5grs motor than a similar aircraft with shortened chord length to get the bonus. This is due to the much lower wing loading of the larger wing chord.
If you have little or no experience in building and flying rubber band powered model aircraft, choose the AF-22 Wasp or AF-23 Hornet. You may also elect to get the CF-3 package which contains both these aircraft. You can then use a KI-9 or KI-12 prop that you can cut down with scissors to meet the required maximum propeller diameter of 20cm. You can also use the ultralight condenser paper to further reduce weight on these aircraft.
The AF-31 Shrike is a real top notch competitor for this year's Science Olympiad flight competition. The Shrike is fairly easy to assemle and fly. Super glue is required for the aircraft frames. It comes with a KI-9 propeller in the kit and will come out at about 7 grs or less without the rubber band. It now also features condenser paper covering. It flies extremely well with a .079", .086" or .093" rubber string, depending on altitude and temperature, so we strongly recommend that you order our CFM1 motor pack if you are serious about winning.
The brand new AF-16 Falcon is designed specifically for the 2010 Science Olympiad rules. The Falcon features a lifting horizontal stabilizer design for additional lift. The kit comes with a competition KI-9 propeller and condenser covering paper. You should have prior building and flying experience before you attempt to build and fly this kit. Prototype planes came in right at 7 grams without the motor. You will need to optimize the angle of attack of your Falcon depending on your location altitude and ambient temperature.
To maximize flying times, you will need a variety of rubber motor sizes like the CF-M1. A winder is an absolute must.
Have fun and good luck.
