The Excalibur was designed as "clone" [1] of the Quad City Challenger II aircraft. The company took the basic Challenger design and incorporated many changes, including mounting the engine upright allowing larger propellers and the Rotax gearbox to be mounted, lengthening the tailboom and enlarging the tail vertical surface to increase stability, shortening the ailerons and replacing control ...
The new design differed so much from the original Excalibur, that a different model designation was needed. It was first given the temporary designation L-104, then it was later officially designated the Model 49 or "Excalibur A". In time, the Model 49 would become a completely different aircraft from the original Model 44.

The SA26 Merlin is a pressurized Excalibur fitted with a different Lycoming TIGO-540 6-cylinder geared piston engine. The TIGO 540 was used despite the fact that one of the reasons the IO-720 was used in the Excalibur was that the Queen Air series' IGSO-480 and IGSO-540 engines from the same manufacturer were so troublesome.
Excalibur is expected to commence testing in 2026. [62] On 24 July 2024, following the passing of a critical design review, BAE Systems had reportedly already begun manufacturing and assembling of the flyable technology demonstrator. Most of the aircraft's parts will be produced in the UK with the involvement of over 100 suppliers.
The 3203 was developed as a replacement for the Hirth 2706 and as a competitor to the 64 hp (48 kW) Rotax 582.It replaced the 2706 in the Hirth line in May 2002. The engine is similar to the Rotax powerplant in being a two-cylinder in-line engine, with dual capacitor discharge ignition, although it is air-cooled, compared to the 582's liquid cooling.
