Y'know, much as I hate to admit it, I'm getting bookworm's point here - in a co-ordinated turn, the force is still directly perpendicular to the wing / parallel to the vertical stab, so the wing is equally loaded, and there is no 'more lift' from the more horizontal part of the wing. Seems dihedral would only help when the 'weight' vector is off axis. Hmm.
Come to think of it, I'm sure I can recall gliders which required positive out-stick to stop their tendancy to roll into the turn, however, that doesn't explan why all the short winged noisemakers I've flown *do* seem to require a little in-turn stick... and I do know what a co-ordinated turn looks like
WRT spinning - what BackPacker, and everyone else said! Mind you, I think rusty sparrow is overstating the case rather.. never met an aircraft that could enter a spin instantly yet; it may flick at the point of stall, but if you stop yanking back on the controls it'll stop long before a spin develops
Still, don't mess without adequate supervision and knowing what might bite you. Please!
