Contest Rules and Guidelines

Team Requirements
Team must be composed of both under classmen and
upper classmen with at least 50 under classmen
Pilot must be a member of the Academy of Model
Aeronautics
All design, analysis and fabrication is the sole
responsibility of the team members

Contest Rules and Guidelines

Aircraft Requirements
May be of any size and configuration except
rotary wing or lighter-than-air
Wing span can be no greater than 9 feet
Must be propeller driven and electric powered
with unmodified components
Must use over the counter NiCad batteries
Gross aircraft weight can be no greater than 55
lbs.
Minimum cargo of 2 liters of water in specified
containers of 500ml 1000ml or 2000ml capacity
Must be able to takeoff is less than 100 feet

Contest Rules and Guidelines

Mission Profile
Aircraft will be designed to carry the greatest
payload possible over a specified course using
multiple sorties
Multiple sorties are encouraged
Ground handling, take-off and landing performance
are paramount design considerations
Flight crew composed of pilot, observer, and 3
ground crew
Judging
Each team must submit a written Design Report
consisting of a proposal and an addendum
Overall ranking will be report score multiplied
by total payload carried
