Any of the "Big Three" radio systems will do just fine. I've flown with Futaba, Airtronics, and Spektrum/JR and they all are fine radio systems. You will get good service out of any of these systems. Find what is useful to you, what feels good in your hands, and go with it. You can also add Hitec to that list. They all do just fine.

People recommending a specific brand do so because they are most familiar with those particular radio systems. Basically, they all do the same things. Different manufacturers have different "bells and whistles" that you may or may not ever need.

My advice would be for you to pick what fits your needs and your wallet.
