RGASS ORIGINAL AIRFRAME
LF-2944
The aircraft that started RGASS.
A large, scratch-built twin-electric fixed-wing UAS prototype developed around modular payload support, autonomous-flight integration and the ability to evolve through practical engineering and testing.

THE AIRCRAFT
A modular fixed-wing platform built from the structure outward.
LF-2944 was conceived as a multi-role UAS rather than an aircraft tied to one sensor or one mission. The airframe uses conventional balsa and plywood construction, allowing components to be inspected, modified and repaired while the system develops.
ORIGINAL DESIGN TARGETS
Development goals — not flight-verified claims
- Maximum take-off weight45 kg target
- Payload capacityUp to 30 kg target
- Cruise speed72 kph target
- Maximum speed98 kph target
- Range400 km target
- Alternative energyFuel-cell development path
These figures come from the original LF-2944 development datasheet and are presented here as historical design targets, not as demonstrated operational performance.
Design philosophy: the wing and tail provide the core flying platform while payload installation and onboard systems can be adapted around the mission. That modular thinking became part of the wider RGASS approach to UAS development.

WHY IT MATTERS
LF-2944 is part of the RGASS engineering history.
The project brought together large-model aircraft construction, electric propulsion, payload thinking, radio control, ground systems and the move toward autopilot-assisted operation.
That same practical approach continues through RGASS work on fixed-wing UAS, flight controllers, FPV systems, antennas, power systems, flight-log analysis and SightNav development.
