Hi Acropad,
The IMAC (UK) season has now finished and I must say its been soooo much fun!
Remember how much fun the early days of flying where when you learnt loads every time you went out....its like that all over again!
I got moved up to National from sportsman after the IMAC Nats this year.

For practise I would learn straight and level flight (harder than it sounds to do well) and then do the same with verticals and 45 degree lines (basicaly the essence of all manouvres). Concentrate on centering the manouvres well and make them smooth. Obviously in all this you will need to learn the schedule too!
Then you'll be ready to start IMAC early next year.

Hope to see you there
Richard
