The Cessna 172R model (our default plane) should be useful again -- I've hand-crafted a new propeller model that at least brings it close to the published performance figures (I realized afterwards that climb might be too sluggish, considering that we're not modelling any weight from the pilot or passengers). There's also a new file, Aircraft/c172/README.c172, with performance data for the Cessna 172R.
You'll need to apply some right rudder during takeoff and climb to keep the plane straight, but you should need little or no correction in level cruise. In a steep, high-power descent, you might actually need to apply some right rudder. If the plane is tending to roll or yaw during level flight at your normal cruise settings, you can just hit the wing leveller on the autopilot, or you can get out and bend the tabs on the wing or rudder next time the next time you're on the ground. For the latter, try playing with different values (between -1.0 and 1.0) for /controls/rudder-trim and/or /controls/aileron-trim Changing these values in your .fgfsrc file simulates physically bending the metal tabs on the tail or wings, as you would on a real Cessna 172. Everyone on the flightgear-flightmodel list has been working hard to make the models usable after a lot of JSBSim structural change; we'll try to get the others working better as well.
