I've got an 8103 and it's only real value over my 6102 is it's ability to take the synthesizer module. There are a couple of little details that are better, but not really of major value.

The 7202 already comes synthesized. If I were you, I'd wait for that. But keep in mind that to use that function, you're either going to have to have extra crystals for your RXs, or you're going to need the brand new 790 RX that doesn't require crystals.

I fly FM (not PCM) with my 8103 and have a couple of the new R720 RXs. Whenever my chosen channel winds up with a conflict, I simply look at the frequency board and pick an unused channel. I dial the TX to that one and then push the button on the R720 and I'm good to go. No waiting for the pin. Less chance of getting shot down.

BTW, I've found that there is an inherent value in the JR line of radios over other brands in the 7202/6102 price range. When I want to change for example, the aileron direction for my new model, I simply find the NAME of the new model and choose that, then find AILERON and change the direction. When I flew Futabas, I'd have to look up which number the new model was and then look up what the aileron function is for Futaba and that was a real pain. I figure the computer in the TX ought to be able to talk in english, not numbers and figure for what I'm paying for them, ought to make those very simple tasks easier. I think you'll like the JRs for those minor little details as much as for the major ones.

And I've flown for over 50 years and never once wanted more than 6 functions in an airplane. Wouldn't have bought the 8103 except at the time it was the cheapest JR that would take a synthesizer module.
