Thanks. Maybe I should have been more specific. I found myself using the throttle a lot to maintain position. I got caught out by not anticipating sufficiently the lag before changing throttle setting has an effect. That's not something which is so acutely relevant in most private flying where one is not (hopefully) in such close proximity to other objects. Unlike in most light aircraft flying you are here controlling speed with throttle rather than attitude. So that was a big lesson from today.
Also, the sheer amount you need to increase speed when you're on the outside of a turn caught me by surprise. How ever did they manage in the early days of WW2 when they used to fly line abreast with 12 machines?!
Of course you're all right -- good leader, good brief, professional coaching etc etc. Impossible to argue with that. The reality is that I'm picking it up in conjunction with another more experienced pilot in his cub and me in mine. There is a correct way to do everything and this may not be it, but it's all I've got, hence the request for tips, which have been helpful.
Thanks again.
