Some of you may scoff at the BN2 but for flying around the Highlands and Islands of Scotland, Inner and Outer Hebrides etc. there was none finer! Muddy strips in between stonewalls and sheep - nothing to beat it!
For shear variable noise and constant power I thought the original 'Melody in Metal'/'Whispering Nissen Hut' SC7 Skyvan took the cake.
