Propwash,
Some good points - however, please don't be so negative towards the so called 'volunteers not display pilots' as regards the vigilant.
As an ex 'professional' pilot of various types and now a 'volunteer' with the Vigilant I can say that the airframe is the limitation (however I'm sure the Wrights would have been pleased with 55Kt climb, 90 Kt cruise) and not the pilot ability, from what I have seen so far the average VGS pilot is very motivated and profesional.
Personally I think that it would be nice to see some of my volunteer comrades flying alongside the 'display pilots'
So long and short of it - lets not be sniffy - we all try to aviate some just get bigger toys than others.
