Whilst we are doing the book reviews, David Robson's fairly recent book on aeros is worth a look. Indeed, it's pretty useful even if you are not especially interested in aerobatics as it includes some clear and helpful stuff on the basic physics of flight manoeuvres and on physiological factors, quite apart from the aerobatic guidance.
As regards aircraft twitchiness, I'll comment on the Cap 10 and leave it to others to sum up the other types available. The Cap feels pretty stable in flight. It is very light on the controls, and, when you move them, the aircraft responds instantaneously, rather than waiting until next Thursday as in, ahem, certain popular types, but I don't think that I would call the aircraft twitchy. It’s worth noting that the elevator trimmer is very sensitive: tiny adjustments produce big changes.
Its takeoff and landing characteristics are relatively benign, as taildraggers go, the main difficulty when learning to fly it being its energetic slipperiness: making the thing slow down and descend takes some getting used to. The flaps don't make a huge difference, and you have to be careful about the flap limiting speed.
Monsieur Mudry liked to keep things simple, so the aircraft does not have a wobbly prop, which I think is a slight drawback, if only because I’m idle, although I feel more cheerful about it when the engineering bills come in.
It's good for your eyes: you can see all around you, and the forward view in the three-point attitude is quite reasonable. It's not so good for your ears, as it’s quite noisy in the cockpit, especially with the air vents open on a warm day. I must upgrade my headsets to ANR. On sunny days you have to wear a baseball cap, which puts you at some risk of being mistaken for a helicopter pilot, oh dear.
On the ground, taxiing in a stiff breeze needs a degree of alertness, especially once across the wind, as the large fin and fuselage keel area encourage pirouetting, so stir your feet. Think of it as equivalent to a step-class workout. Buns of steel in no time.
Overall, however, a most enjoyable package and I have no regrets about buying into one. Hey, it's got elliptical wings, and how cool is that?
