DX7 Gen 2 vs DX8 Gen 2


Hi, looking to get back into the hobby after a long layoff and checking out radios. I see the DX7 Gen 2 listed at 299 tx only, 349 tx/rx and the pre order DX8 Gen 2 at the same prices. My question is, what besides the channels are the differences that would make the DX7 and DX8 the same price? Why would you buy a DX7 if the 8 channel version is the same price? Am i missing something here?

If the DX8gen.2 is priced the same as DX7gen.2 then it should be a no brainer

The idea is to get the most today to save tomorrow.

Take the DX8. It has diversity antennas. Better RF coverage. There is no reason to get the DX7.

Or go for a DX9. The last radio you will need

Perhaps not the last

But it will be a long time before you need more features. Very few airplanes need more than 6 channels but when they do, the DX9 will meet most of those needs.

Sorry to barge in, but which would you guys pick in this situation. New dx8g2 for 270, or new closeout dx7g2 for 170. Is diversity worth $100 assuming I'm not considering the 8th channel as a need for me?
Same price it was a no-brainer, 100 bucks makes me think about it.

It's more than just diversity and 1 channel. Compare them on the chart! (Note there is an error about tx diversity in the DX7).

Thanks Andy, I ended up going ahead and ordering a DX8g2. Better over featured than come up short later on I suppose!

The DX8G2 is pretty much a DX9 with one less channel in a DX7G2 case (with a couple other minor things turned off). The DX7G2 is pretty much a DX6G2 with an extra channel and a knob. Big differences between the two and the DX8G2 is much closer to being a midpoint between the DX6G3 and the DX9 than the DX7G2 is.

I'd pick the DX8G2 over the DX7G2 in pretty much every case if I can afford it. I'd probably take the DX7G2 over a DX6G3 at that pricing (the DX6G3 also has diversity, but you give up a channel to get it, otherwise they're very similar, I'm a glider guy so I really want 7ch to support FH+motor gliders, but after that it's flight modes and sliders that are make/break features rather than channel count)

That said, I'm a big proponent of buying as much Tx as you can afford. With today's high model memories your Tx is going to last a while and be usable with pretty much every model you might own. Given that, it makes sense to buy one that can handle anything realistic you can throw at it.

I went for the DX7 - just delivered yesterday. Thanks to the bad info in Spektrum's comparision chart, I didn't discover that the DX7 doesn't have the diversity antenna until it was too late, but I still think it's the best value right now. Other than the antenna, I won't miss anything in the DX8. My dilemma was in choosing between the 7 and the 9, which was mostly an aesthetic consideration - I like the metallic face of the 9 better.

Ultimately I decided it will likely be a long time (if ever) before I need those extra channels, sliders, flight modes, mixes, etc, and then the 9 - or something even better - will be on clearance. ;^)

In the end, it's hard to go wrong with either, especially if you fly line of site. What shifted me to spend the extra cash on the dx8 was I might build an fpv rig down the line. I'd guess the diversity antenna in the TX might be most beneficial if you aren't paying attention to the TX orientation while wearing goggles? Also the dx7 wasn't out very long so setup files will likely be more abundant for the dx8 down the road.

The setup files are the same file for anything DX6 to DX20. DX7 setup files will continue to be from one of the other radios, just like it is now for all of them.

Mawz, that's a great point. I can see myself a year down the road wishing I got the dx8 vs wishing I should have saved $100 a year ago. Also, I figured if diversity saves me just once, it probably paid for itself.

Oh okay, good to know. I figured it was model specific since the switches/positions and knobs/no knobs varied among the range of models. Looks like most of the switches are similar in assignment.

The difference is that some are 2-pos and some are 3-pos. When that's the case, you lose access to the functions that are on position 2 of a switch.
