View Full Version : DX7 or DX6
When I can find a Trex se REAL v2 I will get it, as far as tx goes do I need, or should I spend the extra $150 for DX7 vs DX6? Now I only plan to fly the 450, but who knows, maybe a 600 some day? Only flying for about 2 months now!

I would go with the DX7. It would serve you better in the long run, especially if you get a bigger bird later on.

I agree with fllyer get the DX-7, with the DX-7 you get the latest DSM technology, more features and a better radio overall IMHO. Im a noob on the Freak and I just ordered my DX-7.

I purchased a DX6 first, I then sold some radio gear so I immediately sold the DX6 and bought the DX7, I don't regret it at all.

Get the "most" transmitter you can afford. At this point in technology "releases" the DX7 is an excellent choice. I have/had an 8103, 9303, DX6, 6102DX6, and now fly everything on a DX7.

the DX7 usually comes with a 2 part receiver, and four giant servos that are not usable in the trex450, the link below offers a deal without the servos and comes with a smaller reciever. the 2 part receiver (AR7000) that usually comes with the DX7 is good but not as easy to find spots to install them. the receiver (AR6100) in the link below is just as good (from what i know) but smaller and easier to manage.
if you hurry they might have some in stock. i know they just got a shipment in on the 1. mine should be arriving on the 7.
just a thought...

I have to disagree with your claim the AR7000 is not as easy to install in a T-Rex450. There's so many mount points on the T-Rex you could mount 4-5 recievers if you wanted to.

valid point jermo. i only said that because thats what i have heard from the majority of people.

my biggest problem with the AR7k is that the reciever simply won't operate without the satilight Rx which imho is poor design since it's designed to switch the EITHER in fight to get the best signal. That would tell me if the satilight rx isn't reachable/usable the main should work solo. Unfortunately spektrum didn't see this in the first run. Let's all hope they fix that in future firmware revisions of the AR7k

To nit pick just the tineiest bit :)
It will work with either one, it just won't power up and do the initial link up with the satellite missing. The RX pair do several "Quality of link" tests at power up and won't move a servo if any of these tests fail.
If this was different, how could you verify your second receiver was working? Don't say "look a the light", I can't see the light when throwing the power switch on an airplane with both receivers inside... So I depend on the system to test for full quality on BOTH receivers, or refuse to move servos.

I agree I didn't state it well :) , I'd like the AR7k to work with OR without the satellite, That way if it's damaged and in for repair/replacement I'm not fully down. As it is now I have to keep a spare RX (AR6k or 6001) just in case (I keep the 2nd rx actually for my future 2nd heli ;) )

Seems to me you'd be better off with the DX6! Have you seen the problems that people are having with the DX7? This forum is full of DX7 problems! Just MHO. :)
Once you get to know the intricacies of the DX6, it's quite the transmitter!

I flew several helicopters with the DX6 from shortly after the DX6 was released.
When the DX7 came out, I upgraded.
The DX7 is much better in terms of features than the DX6, but the difference in flying on vs. the other is phenomenal. There have been discussion or CCPM latency in the DX6 on the internet for some time. These are not just rumors.
The DX7 handles CCPM much better, and the response, in general is much better.
There is no comparison.
If you have a choice, go with the DX7.

im happy with my dx6 to a point. i have found the 3 point pitch and throttle curves frustrating. at some point tho imgoing to get a dx7 prolly when i move up into a 600 class heli or larger. my next heli is going to be int he 500 to 550 class i guess thats what it called, ive narrowed it down to a hurrican 550 or a swift 550. thats the largest i will feel comfortable going with a dx6. i havent noticed any lag issues or ccpm issues with my dx6..

The item that I think justifies the DX7 all by itself is subtrim. The DX7 has it the DX6 does not.

sorry man the dx6 has sub trim..

I am thinking myself about a spectrum. And the research I did till now:
1. DX-7 has the improved 'DSM2' system compared to the DSM which is on the DX-6 - more range, faster response etc. BETTER...and we are here talking about the transmitting tehnology which is very important
2. DX-7 has dual rates and expos for all 3 axis ( roll, nick, tail rotor (aileron, elevator, rudder) ) while the DX-6 only has it for the first 2 (NO RATES/EXPO FOR RUDDER/TAIL ROTOR)
3. DX-7 has 5 point curves and DX-6 has 3 point curves.
4. Larger display -> easier programming (for the DX-7)
5. 20 models for DX-7, 10 for DX-6 (10 are enough anyway)
6. "Model Match" protection function - the model doesn't respond if the model on the radio doesn't match the model you are trying to fly. I dont think DX-6 has that (not sure!) ... pretty cool feature anyway
7. 3 Flying mode + Hold (each mod has own trims and gyro rates) I dont think DX-6 has that (not sure!)
8. More swash types in the DX-7
So my guess...you should get the DX-7 because it's good to have a good radio beacause you dont change that every day. So...invest :) (and i think the price difference is quite raported to the extra features)
All stated above are infos read from the Spektrum official website. If you have any experience that proves me wrong please feel free to correct me and i will corect the post too.
"Hope this was helpful to you...And ENJOY" :D

the dx6 has normal, idle up, and throttle hold..
the new dx6i is pretty much a different designed dx7.. if it turns out to be that good when its released im pick one up.. but its still unclear if it is going to be released by its self or not. right now its part a rtf kit for the eflite 400
