Martin Hollmann of US company ADI contracted by DAC to transform wood/composites Dieselis into RangeR, with changes to structure, fuselage size and wing section. Alex Swagemakers of TTA redesigned Opel 1.7 litre turbo-diesel engine for aeronautical use. Incomplete Ranger prototype (PH-DAC) exhibited at Aero'03, Friedrichshafen, April 2003; first flight then due in USA later in 2003.
