Hello TM. Sounds like it might just be the odd 20 or 30 mins chock to chock, so difficult to get high enough in the time for spins/aeros (NB also civvie Moths without strakes can't be intentionally spun, ex military ones with strakes can be: if in doubt get in the yellow one). Still, probably worth going if you haven't started on the Tiger Moth course at Cambridge yet. Post amusing tales of your progress there and you might get rewarded with a free upside-downy session in something that's wooden (but only has one set of wings).
