Your new to this and will be flying on a buddy box, right?!? That being the case JR is different in that the buddy box needs its own battery pack. The Hitec, Futaba and Airtronics don't require battery packs in the trainer boxes. Due to that and the fact that Airtronics or Futaba may be more popular in the RC club, the club may have those brands of buddy box to help new flyers. Hitec and Futaba will work together, but the rest need the same brand of buddy box to match!
