The transmitters/receivers that come with the park flyers for sure have a much shorter range than normal RC equipment. Also the park flyers in general are made to be light, not strong. The flimsy foam that most are made of turns to confetti if it strikes something and as such is the opposite of a sturdy easy to repair trainer that is made of balsa and plywood. Best I can suggest is to join an RC club and talk to the instructors. They will probably suggest getting a good standard trainer such as a Sig Lt40 and a Futaba radio.
