I'm new to model R/C so if I sound like a noob, best chances I am a noob!

Anyway when learning to fly is a buddy box to your instructors radio needed? Has anyone learnt without a buddy box with the instructor over your shoulder. I'm not a total hack as I have flown real aircraft solo (have only 35hours) so I know the principles of flight however flying R/C is a lot different.

Am saying this because very few people have Airtronics radios in Australia. Therefore instructors with another airtronics radio I can join mine too would be nearly non existent.
