Our prototypes
Lapyx 4
Our latest prototype, Lapyx 4, has recently been completed. It is a direct iteration on Lapyx 3, featuring a larger 4-meter wingspan, upgraded electronics, and a fully integrated autopilot. Thanks to major aerodynamic improvements, Lapyx 4 now carries 225 W of solar panels for sustained flight. Although a mechanical failure caused a crash after an otherwise flawless maiden flight, we are rapidly rebuilding the aircraft with improved hardware to reach our goal.
Lapyx 3
Lapyx 3, has recently been decommissioned. It was a direct iteration on Lapyx 2. Therefore it has similar dimensions: a 3.2 meter wingspan and a weight of 2.8 kilograms. Flight dynamics have been improved a lot, this will enable Lapyx 3 to have solar panels on board. Upgrades will be made on Lapyx 3: add solar panels, implement an autopilot and add an onboard camera module.
Lapyx 2
Lapyx 2 was the first prototype to demonstrate a fully airworthy system, from launch to landing. It was born from the failings of L0 and L1, and set the first performance benchmark for development of future prototypes.
Lapyx 1
Lapyx 1 aimed to achieve powered flight by building on the failings of its predecessor. Though it was able to launch successfully and rise to a suitable flight altitude, the aircraft encountered flutter – or resonance – when entering a turn. It was brought down safely but deemed inoperable.
Lapyx 0
Lapyx 0 marked our inaugural effort to create a flightworthy airframe. Design flaws led to an unbalanced and structurally inadequate aircraft. Despite crashing seconds after launch, this prototype’s development and flight attempt were crucial for learning and team experience.
