A bit of advice here, answering questions you didn't ask yet. Before buying anything, contact the club that uses the field he wants to fly at and talk to at least one of the trainers. With my club, traning day is very casual and there are usually 10-15 people there. Ask what to buy and where to get it. The trainers at the club know what has worked well for their students before and can save you hundreds of dollars in crash damage if you will listen to them.
