After doing my 120 hours on Chipmunk (ab initio) I was moved to BALLIOL T2. I've no idea of its ceiling or its roll rate,can't even remember its stall speed, but I'll never forget its Gotcha ! Go around: Failure to get the stick well forward before whacking the throttle open will result in a flick role; you will know how lucky you are as it cart-wheels: when it's standing on its nose,is it going to fall back on to its belly, or on to the cockpit transparency ? The joke of the flight line chief regarding the Merlin 35 was,"Actually,it's just a Merlin 3 with a Merlin 5 carburettor." It still produced 1250 h.p. Wish there were still some about.
