Hello!
here know your facts first What Next....
Sorry, I'm not an English native speaker, so I may use terms that may not mean exactly what you mean them to mean. If you know what I mean?
Using the term "stable" I intended to say that the heavier 172 will be thrown around less by thermals and gusts, both during cruise and during landing. So there is less work for the pilot to keep it straight and level. Or pointed at the runway during approach. Or pointed at the end of the runway whilst flaring. It has more inertia and a stronger engine, so it can be flown out of the stall easier than the 152.
But then, I really have no idea what I'm talking about. I haven't touched the controls of either the '72 or the '52 in years, although I keep instructing on both of them. Both of them are so easy to fly that I don't have to touch the controls ever, not even with zero hour beginners
Greetings, Max
