My only real gripe about the Bulldog was its fuel system - ISTR it has a quasi-injection system, rather than a carb a la Chipmunk, but it still can not maintain power if continuously inverted for more than a few seconds.
The gripe about the Tutor, which I've not flown, is far more basic. It's not painted like an RAF aircraft, and looks far too much like a weekend flier's steed as a result. Why can't they have a colour scheme that is a bit more military?
