Can you get to a LHS as they feel different to hold and the DX8 is more future proof with SD card for firmware updates and then you have the DSMX feature too, what about a DX7s ???

DSMX
11ms response time
I feel that there is a better grip/transmitter shape
Fully ball raced gimbals
Backlit screen and the screen is much clearer overall
Auto timer on throttle out
SD card slot for additional storage and firmware upgrades.
Easier to adjust stick tensions through rubber plugs on the back
Better menu system with quick scroll adjustments
Don't have to turn off/on to change model memory


Just to name the main advantages for me, there is also Telemetry for all kinds of information from your model.

I've used Laurence's & over the DX7 & i like the anti slip on the sides so it feels more secure in your hands especially in the summer with sweaty palms lol. The automatic countdown timer is a HUGE plus meaning no more forgeting to start it so your lipo's are safer & i guess your fuel tanks. Well that's the 2 that stand out for me as an improvement over my DX7. However i still think it's a bit cheap & ugly looking in comparisom & would probably choose a DSX9 myself if i was to replace my TX

My Dad own a Dx7 and I have recently got a DX8, I much prefer the DX8 with all the extra features it has. The sticks feel nicer and some of the features are very helpful. The timer can be set to start once the throttle stick is raised beyond a certain percentage which eliminates the possibility fo forgetting the timer which on the DX7 is in a stupid place. You can have the gyro Gain change between different flight modes which is a big plus. The SD card is useful meaning you can back up your model memorys and transfer between transmitters. It also has DSMX which will probably be useful at big events etc.

DX8 all the way.

been very happy with DX8, had a DX7 before still a good radio

I love my dx8 to bits,but mine along with several others has been back to horizon for calibration.

Ive had my DX7 for 2yrs now, found it an awsome TX never failed, although i would prefure a DX8 as it has some nicer features and menus, looks easier to use.
So when i have the dosh my dx7 will be replaced with a DX8

I've had my Dx7 4 years and has been fault less

I have a DX7 well used now, and a new DX8.
I'm liking the DX8.
ITs easier to setup you governor as you have a 3 position switch for the governor channel - so you can middle off, up one head speed, down the other head speed.
3 position rate switches too.
Yuo can have throttle cut on a button.
You can disable trims if you have flybarless.
Timer can start on open throttle, DX7 you forget the timer most of the time.
Balances on the eye bolt for a neck strap.
You can have rudder rate switch and throttle hold working and governor on a switch.
It has electronic cytclic ring - significant for flybar helis.
You can have cyclic throttle mixing and rudder gov mixing without having to drop something else.
Save models to SD card and transfer them to another Tx - so your mate can fly your model on the other mode if he hads a DX8.
Trainer fuinction allowing transfer of only a selection of controls to the slave tx or all of them (teach someone the cyclics while you keep the collective and rudder)

Theres an extra channel left if ever you want inflight mixture or something like that.

However other than the extra channel most of this is on the DX7s too.

But the original DX7 is unobtainium new, you'd be looking at used sales and people are hangign on to them like glue becuase they are very reliable, but not brilliant in terms of features.

You will only notice 11ms against 22 ms if you are a superhuman. What was 35Mhz? 50ms? 100 ms?
Perhaps Tarique can tell?

Confidence in the DX8 would be 100% if I hadn't launched a plane for its first test with the ailerons working backwards - I had a week of unecessary soul searching over that

the DX8 has the non-configurable inactivity alarm. After 10 minutes you'll wish you had bought a DX7 instead. Or you get used to it, and fire brigade comes breaking through your door because to the neighbors it sounds like the smoke alarm

PS
>>What was 35Mhz? 50ms? 100 ms?
strangely, pretty fast usually, uniformly random in the 0..20 ms range, as that's the frame length of a 50 Hz standard servo pulse. A plain FM radio (non-PCM) has basically zero delay.
Quite a lot of people take the latency issue rather seriously. Although discussing it on the web is hopeless, "hopeless" in a sense of arguing that the earth is not flat when evidence to the contrary is all around us

Chaps,after chatting with cagey yesterday i think he means the dx7s

Hahaha, lol our bad.....

In that case if your not interested in a blacklight lcd and an extra channel the DX7S looks like it suits you needs, its £229 at fastlads with an 8ch rx compared to £295 fir the DX8

I agree the inactivity alarm is more annoying than discovering you radio is flat because I left it on.
Though leaving the radio on might be a lot more of an issue if it has a lipo fitted rather than nimh!

Tghe inactivity alarm is annoying.
But the fact you can't adjust it, or make it inactive, and it doesn't time out and stop, is unforgiveable.
It is also fixed on sound and vibrate (while otyher alarms can be vibrate, or sound or both of nothing), so your Tx might start to make its way across a table towards the edge before you get back to it.
DX7S is the same.

I was looking at DX7S vs DX8 for tx only and the difference seemed like only 20 quid when I was buying.

Most 35mhz radios sent 1 channel every 20ms I think, so it was a while between the first CCPM servo got its signal and the last, espacially on futaba which had the one ccpm servo first and the third one last with all the other channels inbetween - JR made the ccpm signals at least one after the other. But I don't really know as I read it all on forums...maybe that was just when it was PCM.


If the choice is between DX7S and DX8, then pricewise the DX8 is hardly any more so get it as you will liokkely meet more DX8 owners than DX7S - and the model data on the DX7S is not transferable by the SD card to a DX8 as the data is all different format so I heard. That is a pity. If the 8th channel isn't used you should be able to transfer the data between the txs.
