Matthew Chalker & CeAnn Chalker

2. Wright Stuff Basics
Allowed 2 Ultra light aircraft built and tested prior to competition
Flown indoors
Timed for duration aloft
No Impound
Aircraft to be labeled with team’s identification name & number
Must be a monoplane with single propeller assembly

3. Wright Stuff Basics Allowable Materials
Wood, paper, plastic film covering, carbon fiber, and glue
Thread, wire, plastic tubes & rubber bands may be used to attach major components
Any dense material for ballast
Flight log for 10 previous flights before beginning their test flights at competition

4. Power for Plane Plane launched from hand
Plane powered by wound rubber band
Uses a propeller

5. Building Specifications -
Total mass of plane must be at least 7.0 grams (without rubber motor)
40.0 cm max horizontal projected wing span
maximum wing chord – no limit
28.0 cm max horizontal projected stabilizer span
maximum stabilizer chord – no limit

6. Building Specifications
Propeller
Single two-bladed commercially made plastic propeller
Maximum diameter of 20.0 cm
Trimming, shaving, twisting allowed
Rubber Motor
1.5 grams maximum mass (includes O-rings)
Only 1 motor per flight allowed

7. Flight Log 6 parameters for 10 previous flights prior to competition
3 required parameters
Motor size before windup
Winds on the motor at launch
Flight time
3 Additional parameter examples
Turns remaining at landing
Estimated peak flight height
Estimated flight path diameter
Torque at launch

8. Competition
8 minutes to launch their 2nd flight after their 1st declared official flight begins
Motors impounded after check-in, are available only for official flights
Teams must declare before any launches during the 8 minutes if it is an official flight or a trim flight. If not declared any launch will be considered official.

9. Competition During 8 minute Flight Period teams may:
Make adjustments & repairs
Launch trim flights
Qualify additional motors
Timing will be to the hundredth of a second
Timing ends when any part of plane touches the ground or comes to rest on any obstructions (even if prop continues to rotate)

10. Competition – Competitors only allowed in testing/flight area
Test flights allowed throughout competition at the discretion of the Event Supervisor, ending at least by the last 30 mins. of the tournament
Test flights will yield to official flights
Multiple aircraft may test fly at once

11. Scoring -
Winner is team with the longest flight time for any single flight
Ties broken by second flight time

12. Bonus – WS
State – 30% of the flight time will be added if the plane’s wing chord measures less than 7.0 cm
Nationals – 40% of the flight time will be added if the plane’s wing chord measures less than 6.0 cm

13. Deductions & Violations –
Flight Log discrepancies
Incomplete flight logs will have 10% of the flight time deducted from each flight
No flight log will have 30% of the flight time deducted from each flight
Rule Violations without a specific penalty will be ranked after all teams that do not violate the rules
