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 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.
The Excalibur gives U.S. brigade commanders a precision weapon that is locally available, regardless of weather conditions (unlike bombs dropped from aircraft).
