Five airframes

Each aircraft below exists because the one before it ran out of answers.

  • Lag-0

    Lag-0

    As the first successful member of our now wide variety fleet, the Lag-0 stands as the living proof of time and effort against challenging circumstances. Although it has been made of wood and foam and has little but promising flight time, it is the pioneer of many that has come after it and many more that is to come.

  • Lag-2

    Lag-2

    First imagined as a training plane to show new members the process of designing and developing a plane turned into a high wingspan monster that has many successful flights and a plane that taught the next generation how its done.

  • Lag-3

    Lag-3

    The first competition experienced plane of the bunch is the Lag-3. As we joined Teknofest 2025 with it and became finalists for the first time we were rightfully proud of this plane and its capabilities. We had broken it 9 times prior to the finals and once we got there we had perfected it. With a glorious aerodynamic body and high speed, this demon could finish the 5 minute aerobatics mission in only under 3 minutes, breaking the records with not just its insane fail count but its speed as well. With that help of experience we flew it perfectly in the competition, earning us our 7th place in nationals.

  • Lag-4

    Lag-4

    2026's Teknofest attendee the Lag-4 is the most optimized, if not, the better and best version of our previous Lag-3 and its legacy. Summing up the experience we had gained from the year prior helped us focus on our rights and wrongs and finally got us to perfect the designs we tried so far. Now equipped with a carbon fibre body and stronger subsystems, the Lag-4 is a menace to deal with in the flight area.

  • Lag-X

    Lag-X

    Forcing our team with its criteria and flight control in the international SUAS competition 2026 is the Lag-X, our team's first drone and multicopter with a staggering 9 kg weight and 25 cm width and equipped with cutting edge object detection and autonomous flight software. The Lag-X can stay airborne for up to 40 minutes without breaking a sweat. Using its twin payload delivery mechanisms and visual detection algorithm it can identify targets from 50 meters up, drop the necessary items and go on its path for as long as it takes.
