CONCLUSION TO THE THREAD QUESTION:
Some HobbyZone products might have range problems (that's probably the reason that the company wants you to do a range test before your first flight),

All radio makers recommend all customers range check all planes before you fly them. I range check every plane before the first flight of the day everyday and anytime I suspect a problem of any kind.
This is standard operating procedure.
