Why the wired connection... because you did not pay attention. The DX8 does not have the wireless connection ability as the instructor radio. I did not want to do anything to the DX8 proven setup, so we used the DX9 as the buddy.
I used another master choice and was then able to trim. Still, I think the trims should have worked when the slave selection on the DX9 wired connection was used. Seems logical to me, but then what the heck do I know.
I have used the wireless many times and like it. It just does not cover all the types out there. I gave the guy a DX5e radio to solve future situations.
