time able to concentrat in the air, how very true, everyone i've sen inculding me has a limit of a bout 3-4 mins the first flight ever, rises to maybe 10 after a while, as long as the tank lasts. what sorts thi is gliding, my mate could fly ok, but would give me his tranny afer 5 mins coz he couldnt think anymore, i had the same untill i flew one day for 2 hours straight coz i learnt not to concentrate. he got there too but its amazing what it can take out of you.
what you said about letting the plane do what it wants to do without you correcting every tiny thing is spot on, even if it takes putting the tranny down to demonstrate.
