Nutloose,
1 Dog was actually re-sparred by BAe to 'prove' the design. The problem was the price that t'Baron quoted for doing the fleet; thinking they had the RAF over a barrel the price was circa £10k plus 500 hrs labour (ie about £35-40K per ac). The MoD said a polite 'no thanks' and took their business elsewhere.

I've flown all 3 (Dog on UAS, Firefly on JEFTS and Grob on the AEF) and the Dog is, by far, the most military of the three - it also has good visibility, nice stability and an acceptable rate of roll. The Grob has none of those three but does a nice flick roll and seems to glide forever.....The Firefly is the classic 'inbetweener' in my book.
Now, I'm in a desk job and itching to start AEF again.....hurry up!!
