If you want to try competition have a word with Ultimate High, they are doing a beginners comp at Kemble on 20th, you could probably use either the Robin or one of UHs Bulldogs, though with either you might want one of their instructors along as safety pilot considering your current aeros experience. Have a look at the UH website (
http://www.ultimatehigh.co.uk/ for more or give Mark a ring there and see if he thinks you might be up to it.
