BEAGLE:
After my first "interesting" spin I discussed it with David Scouller (the boss) and Bob Cole, both were involved with re-clearing the 'dog at Boscombe after the spinning incidents. The general view seemed to be that the spin was normal and that the problems were caused by mis-handling during recovery.
People start the AOPA aeros course at all levels of experience, occasionally pre-gft but usually with a couple of hundred hours.
How much specific aeros training would a typical UAS/RAF stude have before being signed off for solo aeros? The AOPA course is 8 hours min but it's rare to get people through in this unless they've had some experience beforehand.
Some of the ex-UAS people that we get say that HM 'dogs were faster than ours (we get about 110kts at 70%), but ours are probably heavier because of the instrument fit. There are rumours that one of the other 'dogs is faster because the flaps-up stops are set to give a slightly negative flap position - don't know if this is true (or legal).
Very good point about the T67A; until someone taxied it into a concrete pilot(!) we used one for aeros and spin training - it was excellent for demonstrating the effect of a little bit of yaw at the buffet, even in steep turns!
