Well I log in here as a 15-hour-and-one-solo wannabe PPL, and learn a heck of a lot. In answer to the original question I post only when I think it's helpful - generally to fellow newbees (well ok, to my eternal shame for my first post I piled into the BA038 thread as well and got immediately and correctly dumped to JetBlast!
).
I admire IO540's knowledge and am very envious of his TB20 adventures, but they always reinvigorate my enthusiasm even for my spamcan flying. Thanks IO540, long may you continue
Pace, I gain a lot from your posts too, but I've wondered this for ages and now have a reasonable excuse for asking - why on earth do you consistently post 10540 rather than IO540?
