I remember my 208 type rating......the last thing the man sitting next to me did was feather the prop!.....and hence I learnt the lesson you did about glide ratios's vs drag. I can happily say I coped admirably (although I was sweating like a fat bloke in a sauna) as I have done plenty of time in a ropey old piper cub with no flaps....and thus the art of the side-slip was not new. Still the Van is a great glider.....Ive got the thing to thermal at idle power!
You say the prop would not move?....possibly a gear box issue?...but then there was no Ng increase....puzzling.
Cheers H
