Question
DX6i or DX7? Why spend the extra for the DX7?

Did a comparison of the DX7 vs the DX6i.

Both have DSM2
DX6i is compatible with all existing Spektrum receivers

Main differences I've found:

DX7 : 7 channels, 20 model memory.
DX6i: 6 channels, 10 model memory.

The extra bells and whistles the DX7 has:

Throttle Recovery
Input Select (Switch Select-ability for Aux 2 and Gear)
Dual Rate Switch Select
Servo Monitor
Gyro Sensing
Servo Reverse
Sub Trim
Travel Adjust

Please add anything I've missed, and I'll update the list.

Right now the DX6i is the best value from what I see, considering it can be found at half the price and perform 90$ of the DX7's functions. Hoping some of you can help me figure out if I'm correct.

The DX7 has three flight modes, to the DX6i's two.
You can also automatically switch the dual rates with the flight modes.
I think the DX7 has an extra programmable mix, which just about allows you to do 4-servo glider wings.
And there's room in the battery compartment to stow a bind plug...

OTOH The DX6i balances on the neck strap and has a much more usable trainer switch (i.e. you can reach it without taking your thumb off the stick)

Edit: Does the DX6i not have sub-trims? That's pretty important, but I thought it had them. I'm sure it's got servo reversing and travel adjust...

The Dx6i does have have sub trims. It does have d/r rate switch's. It actually have a seperate rudder D/r and Throttle hold switch. UNlike the Dx7 that has them the same. One thing i didnt like about My DX7. i couldnt use the ruddle D/r because its also my throttle hold. I know my 6103 have a combine feature that let you combine all the D/r to one switch. the only way i have been able to do that on my dx7 is with auto D/r useing the flight mode swtich. which eliminates the fact that it have 3 flight modes.

It does have end point/travel adjust. and one think i like is that the dx6i has a gyro switch. lets you swap between two different gyro gains from there gyro sensing screen. UNlike the Dx7. to be able to do that. YOu cant use the gyro sensing screen and you need to use the gear travel adjust and then you have use the gear switch to swap between two gyro gain's. One is HH on is Rate .

Basically the only difference is that the dx6i only has 2 flight modes. Less models. and one less channel. and less mixing i think. I dont use any of that so it doesnt matter for me.

I have the same question but don't fully understand all the functionality and technicalities...im a noobie into RC

im leaning towards the DX6i which can be had for about $99.00 TX only.

im flying an HBFP with a 3n1 and AR6100e using an EFLITE LP5DSM transmitter right now and wonder what im missing..
the TX is also bound to my Eflite Blade CX2 co-ax heli.

I'll also be looking at this thread for future reference. I can't find the subscribe button, so I'm just making a post so it automatically subscribes me to the thread

EDIT: I found that button under thread tools. I think the layout might of changed, just haven't noticed until now.

Nevermind. My friend Google found a link for me. That price does not include the receiver or the serevos which is just fine for me! Thanks just the same!

If you look only at the features, for a beginner, the DX6i and DX7 are pretty darn close. The extra flight mode, extra p-mix, and extra channel are probably the first things you would want on the DX7, but it might take a while before you want them.

I think it's more important to look at the quality of these transmitters. It doesn't cost Spektrum anything to enable more features. The DX6i is cheaper because its parts are cheaper. So the gimbals, switches, and overall construction are probably lower quality than the DX7.

Does it matter? The only way to tell is to go to you LHS and hold both models in your own hands. Play with the gimbals and switches, ask around about the quality of the pots, and then decide.

I held a DX6i the other day and it felt VERY good in my hands compared to my DX6. I just LOVE the fact it is powered by 4 AA NiMH batteries; not the cheap NiCads that comes with the DX6. The gimbals felt solid and I did not get a feeling that it was cheap or cheesy at all; just the opposite.

But have you compared a DX6i to a DX7? That's what this thread is about. Big difference!

LOL. According to my budget, not flying helis at all is "way much better" than flying them.

Anyway, the question is not how much it costs right now, but how much it costs in the long run. If you buy a cheap transmitter now and need to upgrade later, it ultimately costs more.

The simple rule is: Buy the best ground equipment (transmitter, battery charger, etc) that you can afford. It will give you the best performance while you have it, and it will have the best resale value if you ever need to sell it.

D'uh!

I was referring to Spinup's post about the DX6i maybe having cheap gimbals. I have also held and used my buddy's DX7. I like the feel of the DX6i even better than the DX7. Both are very nice radios, but the price makes the DX6i more appealing if you don't need the extra features of the DX7. I also like the fact you don't have to pay for the huge servos that come with the DX7, or used to anyway.
