JR DSX9 Questions

[jamiem]

Evening all,

am i right in thinking that the throttle hold and idle up switches are reversed on a mode 2 set? I think from what ive found its the case but just wanted to know for sure. If it is the case, i assume its s reasonably simple job of swapping the switch positions and lengthening the relevant wires?

Im also after an comments from people who actually own/use one as to any problems they may have had, any querks etc etc, im currently using a DX7.

I also cant find the manual for download, only the supplement on macgregors site, so any info where i can get that?

Thanks in advance,
Jamie

Jamie, not sure how old your DSX9 is and if this applies to the latest ones too. Something about wires chafing internally. Be worth checking.

I've got a DSX9 mode 2.

In standard configuration, throttle hold is on the top left at the back, throttle cut is on the top right at the back and 3 x flight mode switch is top right at the front.

Within reason, the switches can be reconfigured, but it's a bit of a pain, and there are limits to what you can do.

If you're getting a new DSX9, then look out for a little blue sticker on it - this means it's ok inside and doesn't need the internal wiring mod. Mine is older and I did the mod last night - it's dead simple - just follow the official guide on MacGregor's website, or take it back to the shop where you got it - they should do it for free.

The software is 99.5% identical to the 35MHz set 9xii and is similar to the overseas version XP9303, so any of these manuals would do you to have a gander.

XP9303 manual is here -> http://www.jrradios.com/ProdInfo/Fil...Res_Manual.pdf

Both my 9xii and my current DSX9 have been faultless. The thing that sways me towards them over the equivalent Futaba sets is the feel - the JRs are much more solid in your hands and the sticks are silky smooth. In contrast, the equivalent Futaba sets feel light and plasticky. I think the Futabas are a bit more flexible in their programming, making it easier to re-assign switches etc, but from my own experience, I've just learnt to use the radio in it's default configuration, without really needing to change these settings.

I fly planes as well as helicopters, and this radio does all that I require in both disciplines. They have just gone up in price in the shops massively - I'm sure the chaps at Inwoods the other day said that the radio alone has just jumped to £540 (you should check this for accuracy) with no servos or receiver. I do believe this is a bit much for what it is, and was dubious about the price when I paid £400 last year, but then just about all of the Far East stuff has just jumped up by 30% as a result of the weakening pound, so there's not much we can do about it.

Brian, i dont have one yet, im thinking of getting one.

Thanks Steve, its all price dependant, so will see what i can get one for come monday...

i spent last 3 years swearing at my 9x2. very very limited switch assignments and you often loose funtions. eg if you reassign throttle hold to rudder dual rate you cant move the rudder dual rate anywhere else other than useing flight mode based dual rates.

get a 10c or 12fg and flog your rx's should get good money for then now the extra rate is foobared.

if you use the 8channel rx's on Fasst you also get 2048 resolution like the DX7se

Hi Jamie

Yes this is correct, but it is actually the Rudder D/R on the left upper fwd position not Hold. The hold switch is on the upper left back position.
In the setup screen for each model you can set which switch is hold, which I always set as Rudder D/R.

Anyway it’s the Rudder D/R & Flight mode switched you want to swap, then it’s just like the DX7.

I posted some pictures back when I swapped mine over. To be honest it is a little fiddly to do, only be attempted by the electrically competent!

I was worried that I would straight away be voiding my warranty but Macman (he did work for Macgregors) seemed to think it wouldn’t providing it’s done competently.

Hope this helps.

PS Futaba programming sucks!
I have only had to use the JR manual once because it’s just sooo easy to program. If you don’t believe me, watch Bob Finless vids on the Futaba 10C programming, and make sure you’ve got some paracetamol handy!

Hope this helps.

your joking right?

sure its a little more complex but thats the cost of flexibility...

you can actually assign a switch to do what YOU want it to do! there was actually something a while back from JR in the states basically saying that they dont do switch assignments because their way is the best way to do it!

Sounds about right to me - I've never had to re-assign a switch on a JR transmitter, so either (a) it is the best way to do it, or (b) human beings have this innate ability to adapt to their environment and just learn to use the switches where they are.

I don't think that makes your offence acceptable on here. Please take your frustrations somewhere else.

Bad day or not.
Your out of order.

Save quotes like that for when you're on Runryder

I'm sure the chaps at Inwoods the other day said that the radio alone has just jumped to £540 (you should check this for accuracy) with no servos or receiver.

Just bought my first JR after using Futaba for the last 15 yrs. Got a DSX9 with a RD921 rx, rx battery and switch for £549. (marked down from £616) from TJD. Mat in the shop told me the new prices are going to be in the region of £920.

Bit of a difference to my 12FG. Must say was a little frustrated with the limited switch functionality compared to the 12 which allowed you to change any designation, but otherwise found the software pretty easy to use.

A quick question.

I've put the rx on my R90 which has the spartan DS760 gyro. I used the AUTO mode in the gyro menu and found with the default values of 50%, the gyro wouldn't initialise. I had to increase the values above 60% for the gyro to go into HH. If I decreased the values, the gyro went into rate mode. I came to the conclusion that 50% must be seen by the gyro as 0 and increasing or decreasing the values around this put the gyro into either rate or HH. The values are currently set to 90%.

Anyone else set their spartan up with this radio?
