I found, as I said in my earlier thread, that my gliding experience helped (at least I knew about 'effects of controls', etc). Together with those consolidated lessons (even more important than the gliding experience IMHO at the pre-solo stage when it's all very new), 10 hours did it for me. But it wasn't plain sailing by any means - I remember a comment by one instructor on my student card when I was attempting to learn to land:
"Now I know why gliders don't have an undecarriage!".
