Our Engineering
From airframes to power electronics — everything we build is designed, manufactured, and tested in-house. Browse our aircraft prototypes and the systems that make solar flight possible.

225 W of solar cells laid across the upper wing surface, spanning the full 4.0 m wingspan. Paired with the in-house Daedawatt Ultra MPPT charge controller to push endurance past the ~7 hr Lapyx 4 demonstrated on battery alone.
The 4.0 m span gives the aircraft a high-aspect-ratio wing, reducing induced drag and raising glide performance. That aerodynamic efficiency is what makes sustained solar flight practical at this scale.
Fuselage pod carrying the fully integrated autopilot, flown in both manual and autopilot modes on the Lapyx 4 maiden flight. In-house avionics developed alongside it include the DaedaLink bus and the DaedaFind LTE/GNSS tracker.
Three 16 Ah cells carried in the fuselage, supplying the airframe alongside the solar array and covering the flight envelope when solar input drops.
A 1.08 m carbon-fibre tube carrying the empennage aft of the wing and setting the tail moment arm. The DaedaLink wiring runs through it, linking the motors and FPV camera to the electronic systems in the fuselage.
An analog FPV camera mounted at the top of the vertical fin, with its antenna and video-link system housed in the tail. It streams live to the ground FPV headset and monitor.
