It's important to note that only 2 of the DX7 mixes allow trim settings to be used on the slave channels. Both of the programmable mixes of the DX6i have the option of allowing the master trim settings to affect the slave's trim settings. The DX7 allows you to program 3 throttle curves and 3 collective pitch curves, where as the DX6i has only 2 throttle curves and 3 collective pitch curves. Each throttle and pitch curves for both transmitters have 5 programmable points.
The heli version of the DX7 allows for up to 3 programmable mixes and the DX6i only gives you 2 programmable mixes. If you're new to helis and need some more explanation of these features, I strongly suggest checking out this excellent RC helicopter website! I find it helpful to construct a table summarizing the differences between two products when making a big decision.
So hopefully the chart below will help you feel more comfortable about your choice. Keep in mind that this table only points out the major differences between programming capabilities of these two transmitters and aren't necessarily the only differences.
Another notable difference between the DX7 and the DX6i transmitters is the battery packs. Both come with appropriate chargers. This doesn't seem like such a huge deal to me, but it is definitely something you should be aware of. Some people feel that using "AA" instead of a 4-cell pack makes the DX6i feel cheap and toy-like. I personally think it's an advantage because you can always throw in 4 standard "AA" batteries should you forget to charge the night before. A typical mAh transmitter battery should give you around 6 hours of flight time before having to recharge.
That's a lot of flying! Spektrum's DX7 transmitter comes with digital servos which means you are definitely getting your money's worth with this system. Have you priced digital servos lately? There is a hi-torque version and microlight version of both airplane and helicopter DX7 transmitters. Yes, there are two version of the Spektrum DX7. I am just about to get my first FPv Quad. Thanks Sent from my iPad using Tapatalk. What radio does DRL use?
I'm starting to see a pattern here. Doberman - Just some possibilities of what is actually out there. When I was consumed with just strictly Heli's, I wanted one of these. JetiUSA 1. Nothing wrong with Taranis. It is also worth a look, and I found it easy to program. Many are saying Spectrums are way more user friendly and easier to program.

What is the best budget video transmitter? Replies 9 Views 1K. Questions about getting started. I know you said some 3D but are you doing indoor profile 3D or big gasser 3D? How many channels do you use on your current models? What types of models are you looking at for the future?
How many models do you fly with? Here's a few quick things about the DX's that I've found. The DX6i is a very very capable radio that my good friends fly with most of the same planes that I fly. My DX8 does everything the 6 and 7 do plus more.
I spent the money to have the extra channels so I had a radio I could grow with. I'm not disappointed. There are lots of little things that the DX8 does like the DX6i and DX7s only have two position switches for rates, gyro, governor etc where the DX8 has three position switches. This is huge for me as it allows me to have three settings at my fingertips so It makes tuning a whole lot easier.
For my super fragile 3D indoor planes I have everything set on my flight mode switch. I have a very tame setup for taking off and landing, my normal rates for most all flying I do and then I have it cranked up to max rates when I feel like pushing myself, all by flipping one switch. Now, the other two also have a flight mode I believe, but you only have two settings. This is not really a bad thing not to have, but a great thing if you have it. I wouldn't buy a radio based on this alone though.
Another thing that we found the other day when setting up throws on 3D planes is that I have the ability to adjust my max throws on each servo in each direction independently of each other. My friends DX6i can also adjust the travel, but each direction is linked so he has to set it up both at the lesser amount.
I hope that makes sense the way I'm saying it. Again, it's not a huge deal if you don't have it but it's really nice to have. I can compensate electrically for things he has to adjust mechanically with no disavantages. A huge benefit is the screen. The backlit screen is nice and all but that's not what I'm talking about. The bar graphs showing the position of all the servos is awesome. I'm not sure if the DX7s has it but the DX6i does not.
It has the roller interface and basic screen but you have to do all your throttle and pitch curves, direction, travel, expo etc all by the numbers like a Futaba. The DX8 has graphs that show you pretty much everything. I was doing some complex for me mixing of 4 servos in a combined 4 aileron with flaps setup and i was able to do all of the programming right off the screen and get all the servos moving the way I want, adjust for direction, travel, and make sure I wasn't over driving any servos without ever having any of the pieces in hand.
It also has graphs for pitch, throttle and expo that make it waaaaaay easier to understand. I use my radio to help explain the settings that my friend uses in his DX6i. Does any of that make it worth it? It really depends. I'm sure there's a whole lot more that the more expensive radios can do, but my friend with the DX6i flies just as well as I do My vote is that if you can afford it and you think there's a chance you are going to need more channels later on, I'd get the DX8.
I use the extra channels on my complex foam models and my bigger nitros and helis. I use all the channels but if you don't, the features may not be worth the money. One big feature is the model memory. The DX6i can only hold ten models and you don't have the option of using an SD card to save more.
I already have fifteen models on mine, so there's no way a DX6i would work for me, and chances are I would use up the 20 on a 7s by next year. The SD card options also give you the ability to download setting from the Spektrum online community or share them with local pilots. I used the programming from an expert at the hobby shop to help understand how I needed to program my heli.
I saved it in a slot next to mine and would use it as a reference point while learning to setup my gyro. Looks like the DX7s also has the telemetry options which I think are cool. I'm going to put some sensors on my nitro heli for rpm and temp. The 8 is quite a bit more, the 7s is only a hundred more than the 6i. My vote is forget the 6i and go for at least the DX7s.
I think the easier programming and extra model memory are worth the extra money, plus the comfort items. The 6i is a good radio, but for the extra 99 bucks you get a whole lot more radio.
