Davigal, thank you for the additional info. But all the issues mentioned, the design challenges with larger helicopters have been successfully addressed with non powered, fully castering nose wheels. The only large US helicopter exception to that statement is the CH-47, and Boeing went to a powered left rear gear in 1964, and not because of size or gross weight, but because of a main rotor design issue: the droop stops were set so tight that taxi pedal inputs larger than 3/4 inch resulted in droop stop contact and in many cases, failure of the droop stop, with embarrassing consequences during the subsequent shutdown sequence.
I’m just being curious, as I’ve been to Yeovil and they are very good, therefore my thinking is that they wouldn’t have wanted to make their system that much more complicated unless there was another consideration in play.
