47 posts and nobody has come up with the obvious answer - What could you replace a Chipmunk with? Nothing but another Chipmunk, and I say that having flown every type so far mentioned (excluding the VP1 and the P51) and a few more besides. I have flown only two types that I enjoyed as much as the DHC-1, the DH114 and, even better, the DH104 (one of which I owned for a few months back when I was earning real money).
Oh, and I agree with foxmoth - only a hamfisted imbecile could find the Chippie 'spin-prone' (whatever that is).
Ahhh, De Havilland!
