The RV might well be an excellent alternative to the Chippy 'on paper' and on on performance too. But you could never pretend you were flying a little Spitfire, like what you can in the lovely dHC1.
And the Dripsy Major? Get the 'ring mod' done and they only throw out half the oil they did before! Anyway, it gives the aeroplane even more 'character' than it already has. A Lycominged one just ain't a Chippy.
