jigeye... You can use most any Futaba radio for the trainer box.. I'm not sure which
but some are not are not compatable, but very few.. I picked up a one for our club
off of ebay, I forgot what I paid for it, But think it was around $20... Do a search on
ebay and or here in the market place. You can pick up the cords sometimes on ebay,
or just about any hobby shop.. The newer radio's has the mini square plug and the
older radios has the round plugs.. But you can order any combination of the plug that
you need.. Hope this helps... You can get more info on the Futaba site...
