RE: Why TOWER dosen't sell JR Radio's ?
Great Planes/Hobbico/Tower Hobbies are the same company and are the importer/distributor for Futaba - so why would you sell your main competition.
Same deal for Horizon Hobby - they are the importer/distributor for JR radios.
I don't see why it makes a difference. You can order JR brand from the Horizon Hobby website and get just as good of service from them as Tower....
