• 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

RULES & REGULATIONS• Each team comprises of 2-5 members
• Open to Secondary and IP students (levels 1-4). Team members must be from the same school
• Each team is to design and build an unpowered glider based on the following guidelines:
- All parts of the glider must be fabricated by the teams. Kits or 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- The glider must be capable of being launched from a launcher
via a glider attachment, which will be provided to all participating teams to be attached to the base of the glider
- No balloon and airship design will be allowed. No gaseous substance lighter than air will be allowed

• Submit two 4R sized photo during presentation. No major changes to flying machine after presentation
• Each participating team will be allowed to bring up to two IDENTICAL gliders into the competition hall
NOTE: For more details please check out the Challenge Booklet on www.dsoamazingcompetitions.com.sg/safmc/categories.php

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
