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.
The taped bands mark where the outer wing panels meet the centre section over the main spar. Placeholder copy — replace with the real spar material, joiner type, and how the panels are secured for transport and flight.
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.
Carries the empennage aft of the wing and sets the tail moment arm. Placeholder copy — replace with the real boom material, diameter and length, and how it ties into the wing structure.
Mounted at the top of the vertical fin, held clear of the wing and boom for an unobstructed forward view. Placeholder copy — replace with the real camera, video link and mounting detail.
