glider (of limited wingspan) to be bungee-
launched from a designated launcher to
compete for best range, best track and
optimal performance.

5. • The launcher will be elevated at an inclination of 0o
• Upon tension to the launch position, the total pulling
force on the adaptor plate is about 10kgf
• During the competition, the launcher will be placed on a
0.75m high platform on the stage

off-the-shelf models or parts, i.e. servo motor, receiver,
transmitter, are not allowed
- The glider must have a wing span of between 0.5m and 1.0m

9. FLIGHT COMPETITION
• Each team will be given a total of THREE (3) minute to setup
their unpowered glider on the launcher
• Each team will only be given TWO (2) attempts during the
competition. The attempts will not be consecutive, and will
be in different sessions. Teams are advised to return to their
respective team booth. The team is allowed to repair or
make simple modification to the glider before the next
attempt
• The better measurements between the two attempts will be
taken to vie for “The Best Range”, “The Best Track” and
“Optimal Performance” awards

11. SCORING SYSTEM
Optimal Performance
Optimal performance for each attempt (for each team) is obtained
with the following equation:
 Glider Weight for the Attempt   Glider Range for the Attempt 
OP = 
 Heaviest Glider for the Session    Best Range for the Session   100
  
   
Optimal performance scoring will be recorded after each of the 2
sessions. The team with the highest value will win this award (max value
of 100).
