Spektrum DX7 - Actual Field Results

This thread is intended to capture actual field results of the new Spektrum DX7 RC system. As many of you know, this system is now becoming available for general purchase in the U.S. (our Ausie friends got it a week earlier than we did...). Building on the revolutionary DX6 2.4GHz system, the DX7 is the first truely 100% digital system available for RC aircraft for the general public. Many of you may not know or realize it, but the DX7 has none of the PPM/PCM delays of the DX6 or any other TX out there, since it's control inputs are sent from the TX controller in digital form to the RF deck (unlike the DX6 which took PPM pulses), resulting in the lowest latency possible (as in almost instantaneous). In addition, it allows for simultaneous servo outputs in CCPM helis and such as well.

Anyway, I am excited to start this new thread to discuss how the DX7 performs in the real world, although Horizon/Spektrum and put this through 1000's of hours of testing already over the past year.

Please, just actual, real field experience around system quality (feel of transmitter, etc.), programming (features, ease-of-use, etc.), range (how far can you push range), hit reports (hope there are none), etc.

-Hilgert

EDIT (11 December 2006): Accessing the DX7 or XP7202 Service Menu

Thanks for the notification of the new thread Hilgert. Mine's back-ordered right now. I went with the Heli version as I (might) end up trying to fly some smaller E-copters in the future (own three+ of them now, so I ought to learn how to fly them).

My first planned mod will be adding a D.E. switching regulator and 3-Cell LiPo battery just like I did in the 6102DX conversion. Have to wait to get the radio and check the insides first.

The switching regulator mod is not necessary. DX7 runs at 130mA in DSM2 mode. The main battery pack is 1100mAHrs.

Looking forward to seeing user reports on the DX7.

In particular, I hope at least some owners of the new DX7 will do comparative range tests of the $100 AR7000 and $50 AR6000receivers. The question to answer is: To what extent is Spectrum's park flyer limitation on AR6000 rx due to reduced range and to what extent is it just a marketing ploy to sell higher priced receivers to those people flying mid-size planes? Look forward to learning of the actual experiences of DX7 owners with both receivers.

Van,

You may not need to do this mod. The DX7 uses less power than the DX6. beardp , who posted above, knows a bit about this.

Trust me when I say that THIS is THE radio system we all have been waiting for. If I do the regulator mod, it would only be to put my lipo battery in (I *hate* having to worry about batteries draining in storage). But I'll wait and see on that - for now I am sure I'll use it so much it will have to always be on the charger!!!

My DX7 is set up on my 3 planes now, on the ground it all works wonderfully! Haven't had a chance to fly anything yet (and wont for a few more days), but I'll be sure to let everyone know how it goes.
Other comments... Programming is great, half an hour of sifting through menu's and I'm totally comfortable with all the programming.
The screen has a bar graph to show battery charge state, as well as a raw voltage readout. No matter how much I charge that sucker it wont go above about 90% <voltages removed while I check them, what I wrote doesn't sound right>. I'm keen to see how accurate it is on the way down as well, I'll do some tests to check this.

Thanks for the notification Hilgert, look forward to following the real world results and contributing once I get my DX7.

I agree that field results comparing all three current Rx AR7000-AR6000-AR6100 will be very interesting indeed.

HPSOV: Put that battery on a digital charger and see if it goes any higher.

Hilgert: Give a call if you want.

Wowee !!

Walked into my Hobby shop today to get some training gear for my CX2 , hoping the DX7 would indeed be mid December as that is when I would be getting my company paid bonus....WELL......the clerk was showing one to a customer and another was sitting on the shelf....10 minutes later the shop was out of DX7's and I had a smile on my face as did the other customer
I AM sponsored by VISA ya know !! Can't wait. I have a full compliment (10) rx' on my DX6 and am looking forward to "rebinding" them to my DX7...just hate the thought of retrimming 10 planes.

Geez, I saw this thread and was thinking there would be some actual user experiences here.

Oh well, waiting for input, like everyone else.

There are some actual experiences from our friends Down Under, who started getting their units last week. There will be even more experiences this weekend. I wanted to wait for others to start receiving their DX7's in the US before beginning the new thread.

I'm interested to know the new receivers work with the Hitec HS65's. From what I've heard.. Apparently the 3.3v signal doesn't play friendly with these servos. Which is really unfortunate because they are "THE" servos for a TRex 450 heli.
