I have been doing some searches for adapter cords and some places are saying Futaba will work with Hitec if you use the Hitec cord. You can use the Futaba cord but the batteries and chrystal has to come out of the Hitec. But when Ilooked at the models listed, that the cord was supposed to work with, the newer models weren't on there.I ended up Emailing Hitec service to see what they have to say about it, but haven't heard back from them.I did hear from the head instructor of one of the local clubs. Here's what he said
"Hi Ron,

Thanks for your interest in our club. I am aware of one member using hitek radios in our club. I would not let the training aspect get in the way of your desire to use hitek equipment. There may be adapter cords to allow 2 different brands of radios to be used. I learned to fly without a buddy cord and have also taught people to fly without a cord. Its a little more cumbersome but does not worry me. I would advise to buy the equipment you want to use as training is a very short duration."
One of the hobby shop owners told me the same thing. He was also telling me that he had the chance to teach a student using an Aurora 9. He said it was the best radio he had ever used for training a student. That's good to know if I ever decide to teach my grandkids how to fly. Ron.
