Douglas Airways wanted Trislanders and insisted on castering nose-wheels instead of the directly linked ones to the rudder. Turning circles and all that. Britten-Norman refused and lost 3 sales. The Nomad was then chosen which came with reverse gear. The Trislander was a 'fantastic' machine. Same speed as the Islander on 50% more grunt with twice the payload. The Dove/Heron set the pace for the then single pilot weight and the Trislander's no cabin crew / isle benchmarks.
