Hi,
The Uk standard is either mode 1 or 2...it pretty much depends on the club, mine is a 50:50 split others fly Mode 2 only...I would find out what the instructors fly at your local club and stick with that...after all theyre the ones who are going to teach you. I would also talk to an instructor before you use G2 so you don't pick up bad habbits as they'll be difficult to 'unlearn'.

Simba2k what part of the UK are you from?
Good Luck
