I am probably going to upgrade to the DX6 and I am really looking for some more objective feedback on the DX6 performance and functionality. Especially in light of the possibility of spending more money and getting a DX7 instead.

Are there any regrets out there from those who bought the DX6 instead of the DX7? Are there any functions that one eventually misses in the DX6 that could be found in the DX7?

The DX6 is half the money and already comes with the micro servos. I do understand it is not a full range (distance) radio like the DX7, but for a microheli radio, I am also under the impression this should be of zero concern - true or not?

I also understand that the DX6 can experience a directionally induced radio loss/glitch when the model is flown out at range - a factor which was addressed in the design of the DX7. Has anyone experienced this? I assume this is something that only the airplane fellas experience (not the Heli crowd).

...Looking for an honest review; not the cheer-leading section.

Thanks,

Dave

Dave,

I have the DX6 and I still like it as it is easy to program, and really does every thing I need it to. A lot of people bring up the 3 point throttle and pitch curves but to me I have not found them to be a limiting factor at all.

I was going to get the DX7 last week but my LHS did not have the Heli-Version in stock, so I picked up a couple more T-Rex batteries since I was already there.

I did the voltage regulator mod on the DX6 to increase the runtime and yesterday I replaced the stock 600MAh Ni-Cad battery in the DX6 with 2500MAh NiMH cells; so now it should let me fly for something like 25 hours between charges.

Now that all being said I may still pick up the DX7 “just for fun” more than anything else, as I really like the model match feature.

I have handled both and they both are good radios, the DX7 has a few more features, and if you can swing getting the TX only (my LHS will give me a deal on just the TX for $175), then it may be worth getting the DX7 over the DX6.

The AR6000 RX or AR6001 RX are $50.00 so for $225 you get a good setup.

The S75 servos are not that good so you will probably wind up using something better any way. So in the end the cost is very close.

Good Luck

I'm very satisfied with my DX6. I currently have three helis on this system, my modified HoneyBee CP2, an HDX300, and my T-Rex 450SE. No problems with any of them. They are all brushless motors, outrunners on the smaller helis and an inrunner on the 'Rex. The HoneyBee uses an E-Flite 3 in 1 unit. The HDX has the E-Flite HH gyro. The 'Rex has the Futaba 401 Gyro.

Very easy to program for these three very different setups. As soon as the receivers are back in stock and available once again, I'll have a fourth heli on this system. I'm finishing a build of the MicroHeli aluminum/carbon fiber frame that's available for the Blade/HoneyBee helis.

My only complaint, and this comes from making multiple flights in a day on the three different helis, is that I'd like to see a longer charge life on the transmitter. Generally, in an hour or less, the transmitter voltage is down to the low-battery warning. But then again, I guess nothing is perfect!

My biggest complaint with the DX6 is also the transmitter time. Seems the batt needs charging way to fast....pleased with everything else about it...

There is a bug in DX6's CCPM mode. As you can see, people are using it on CCPM helis and thoroughly enjoying it. But I flew my blade twice and went back to the stock E-Flite radio. I really didn't like the way it handled with one servo lagging behind the others. Especially since I'd paid 200 bucks for it.

So tho I realize that it doesn't irritate everyone as much as it does me, I still recommend that people avoid it for CCPM helis. For a non-CCPM Trex or MX, or a fixed-wing, it's perfectly fine. The DX7 has turned out to be delightful in every respect.

Aside from that, the DX6 is fantastic. It does everything I want a heli radio to do, and range is not a problem. I can fly the length of a football field without any sign of dropouts. You can get fancier curves with the DX7, but the CCPM bug was the only reason I upgraded. I'm still keeping my DX6 to fly planes with. I'm also considering building a CCPM mixer to go onboard my BCP so I can bypass the problem.

There are two things you can do to improve battery life on the DX6. You can replace the voltage regulator with a more efficient switching type, which requires only a simple soldering job, and you can put a bigger pack in, which requires nothing more than swapping batteries.

DX7

I would suggest going with the DX7, first because of the CCPM issues, second the programming is a little more intuitive with its easier to understand screens that have actual text rather than an abreviation and a number. Also it has "model match" which actually has saved my planes/helis/cars 5+ times. My last point is much more of an opinion than an actual fact though, I have big hands as is evident in the pic and it just feels better to me than the DX6.

A bit of a side note that may or may not apply to you...
The DX7 has the full range capability and 4 digital servos and a receiver with it from new so if in the future you wanted to go bigger than it would make it a little easier on the wallet in the long run.

PS, no im not pissed off in the picture, it just looks like that because its fuzzy

I called my LHS today to order a couple more balancers and he told me he should have a DX7 Heli-Version in for me next week.

So I guess I'll be picking up a DX7 after all.

I don't really care for the DX6 for helis. I recently moved my helis back to the 9CHPS. It had nothing to do w/functionality or programming issues. I simply did not like the collective stick on the radio. I did every mod imaginable and still could not get it to my liking. However, it is great for planks which is what it is devoted to now.

I have never flown w/the DX7 so can't relay any personal experiences. On paper the DX7 is far superior to the DX6. If you fly any bigger birds (especially if you have nitros) the DX7 is the route to take. One note, I have been reading about a few people having problems w/the DX7 servos. Don't know if there is anything to this, but you might want to research this.

All in all the DX6 is a good radio. It will work fine for helis, but it wasn't a good fit for me.

even not doing anything would have been better than nothing...

Thanks to everyone for the great input.

Regarding the DX6, I`m not very happy to hear about the voltage (short run-time) issue. Even though it can be "soldered" away and "new Tx batteries" can be purchased.

More significantly though, is the "bug in the CCPM" programming! I had never heard of this at all. Sounds to me like changes in collective can never be smooth and straight. Is this correct? How bad are we talking about here? Are all the DX6`s like this or are recent releases programmed differently?

This last issue is a deal-breaker for me. I can live with (or fix) the voltage issue, but the CCPM problem is another matter. I suspect I am not the only reader who is really keen to hear more about this "bug".

Please, do tell all !

Thanks,

Dave

There has been several post about it if you do a search you will find them.... That is probably why so many are in the for sale section.....

Here are the threads I'm thinking of. One of them has my quantitative analysis of the servo lag in a graph.

http://www.runryder.com/helicopter/t302979p1

But keep in mind that I'm responsible for stirring things up in those threads. Some people are using the thing without problems.

I think it could be fixed in a software update, but I have no idea if they've done anything about it. Spektrum never returned my email about it, and frankly I can't say I blame them.

I fly the DX6 with both the Trexs I have and I love the radio.
I have been thinking about using it on my Blade cp as well because The DX6 is one of the best things that happend to rc if you ask me.

StickyFox,

I followed your links and read the threads in their entirety. Let me just say that your qualification of "stirring things up" is true modesty - in a good sense. I, for one, accept your assertions and admire the way you presented them. I am also glad I read about this today and not tomorrow.

The "bug" may be a small issue to some, but not to me. That kind of radio behavior - should I encounter it - would eventually drive me nuts.

For me, this is a case of "seek and you shall find"...No DX6 for this guy on a CCPM bird.

...Now, If I could only track down a list of programming parameters for the DX7 and the CPP I`d be happy! The recent programming list for the DX6 sure looked like a nice time-saver.

2.4 GHz Spread Spektrum works great, it's just the DX6 tx itself that's not the greatest. So, here's my two cents. Along with two big "if's".

First "If"...If you already have a 6-channel computer tx that you're happy with....AND...

Second "If".....If you can get your hands on a DX6 really cheap (how cheap depends on your own wallet )

Then mod your existing tx by putting the DX6 2.4Ghz rf board into your existing tx. That way you get the benefits of 2.4 Ghz without any of the drawbacks of the DX6. You get your own radio that you don't have to re-program (along with whatever bells-and-whistles it already has) PLUS the advantages of 2.4Ghz. That's what I did with my Optic6. Since I got a DX6 for basically free, the only cost was the original purchase price of the O6, with a little time spent soldering. Works fantastic!

Here's another couple of options. Now that the DX7 is on the market, people are unloading their DX6's cheap. There's also people unloading their Spektrumized JR6102's cheap for those that don't already have a tx.

I am pretty sure I know who you are Dave, and if your the fella thats been coming to rc guys then just come down some day (tell me a day in advance) and you could just sync your eventual DX7 with mine. I have it set darn near perfect in all 3 flight modes with the CP and it is also using the gyro you ordered, GY401.

Once again, i think i know who you are but im not 100% positive, so if you have no clue what im talking about then just ignore this...

Hey Matt,

Yes, I am the guy you think I am. I didn`t recognize you in your photo until I expanded it.

Many thanks on the DX7 offer, I will certainly take you up on that. I have decided to go the DX7 route (as you have probably surmised).

As fate would have it, my stock motor failed last night - momentarily fusing my brushes to the commutator and frying my 3 in 1 - what a toxic mess that was! I could have roasted marshmallows over the smoking carnage. I`m still not sure why this occurred (debris?), but the autopsy on the motor was conclusive regarding the mode of death. It appears the Gremlins held a little an arc-welding party in there - even melted my motor leads!

I called around this A.M. for a 3 in 1 but no one has one locally. I did manage to buy one in Burlington - for pick up this Saturday.

Are you using the AR7000 receiver or the AR6000 in your CPP?

I heard there was a DX7 coming into the store. But, I also heard it was "stickered" for air (not heli). I actually drove in yesterday morning to buy it, but it had yet to arrive. I`ve read the rachet on the Heli setup is smoother, but I suspect this is probably easy to adjust either way. Would you suggest waiting for the Heli version? ...Keep in mind I am in no real rush to complete the second Heli.

Cheers.

Dave

P.S. Did you read my post on the CX2 replacement blade defects? It turned out that the motor was NOT the problem after all - apparently I jumped the gun on that one - it was the replacement blades in the end.

The plane version also has a couple switches moved around. They're all there, and it's functionally identical, but some people are used to the locations of the switches. I like the little picture of the helicopter, personally.

Yes.. Going straight to the DX7 is a better move. There is no looking back once you are on a DX7. I moved down from a 10X to a DX7 and am loving it.

If not mentioned yet, the DX7 flies the DX6 and DX7 receivers but the DX6 will not use the new receivers for the DX7.

So make the jump over the DX6 if you can.

I have a spare 3-1 that i can bring for you tommorow morning for $20 ($50 new) if you want it. Im using the AR7000 right now. And smoking the single motor setup is common.
