Hi everybody,

I've got questions on using a buddy box. One of our club members offered additonal flight training help. I have a Futabe 6XEAS TX and he has an older Futaba (which is not digital). He plugged in a trainer cord and after much head scratching, got the boxes to work. But the only way they will work is if both transmitters are turned on. I thought one of the transmitters (buddy box) did not need to be turned on? The Master TX was turned on, and the slave was to be off. We tried turning off the slave TX, but it would not operate the control surfaces, unless it was turned on. What are we doing wrong? Turning on both TX's and depressing the trainer switch on my Futaba is the only way The older TX will work. The transmitters are different channels, so do I need to get a "Buddy Box". i"m confused. If I didn't give enough information, let me know and I'll go into more detail.

Thanks
CC
