This is the cord that comes with the RTF Hangar 9 trainers. I always used it JR to JR, so I can't tell how it works with other brands. I do seem to recall that it only works one-way. You can use a Futaba as a buddy box, with the JR as master (I think), but not the other way around.

I'm not 100% sure of this, but you may want to confirm before you buy.

Good luck Fozjared. I haven't seen any post from you in a while. Did you ever get another Seawind?
