Buddy boxing different brands
Is it even possible to buddy box different brands of radios?? For example, I have a friend who has a JR on his trainer. I 'm getting ready to purchase a radio for my plane and was wondering if I got a Futaba or Airtronics if we would be able to buddy box the two of them so that he could teach his boy to fly the trainer using my radio? Seems like a silly question but I just can't seem to come up with the answer on my own. Thanks.
