To reiterate, and relate my experiences. You must have a computer radio to buddy box the DX6i, the manual states this.
I tried a JR Quatro and had no luck. So I hooked up my JR 6102 and it works flawlessly.
I am told, though I cant be sure, that the DX7 does not have this limitation so I assume this is a case of we got what we paid for..
You may be right, although the manual is kind of vague on this. It says that the slave "must have the same programming (i.e. reverse travel adjust, dual rates, mixes, sub trims, etc.) as the master". I'm wondering if this applies ONLY if the slave is a computer radio. I've heard of situations where a non-computer slave TX was hooked up to a DX6i with no problems (someone at my club has done this). I also read somewhere (can't remember where) that if the slave is a non-computer radio it must have it's power turned off. If it is a computer radio it must have it's power on, which might explain why the programmed settings would have to be the same.
Anyway, I'm getting the Spektrum RTF of the Alpha 40 more for the RX than the TX so I can bind it to my DX6i. If the buddy box options works, that's just a bonus.
