Just noticed THIS:

A full DSM2/DSMx, CE-marked tranny module for $30 (this is the futaba one - they do a JR one as well) looks rather tempting. If they bung some in the UK warehouse at anything close to that price I'll be sorely tempted to convert some of my old futaba transmitters (the J8, F7 Gold and FFsuper7) to 2.4GHz for use with Orange receivers...

Hi Pete, I've got one, the JR version, and also a Futaba version on order. I bought them to test for the Single-Channel revival project. 
Being impatient, as soon as I'd unwrapped it I connected the JR one directly to one of my encoders, not expecting much to happen as mine are positive-going ppm and open-collector feed (the exact opposite of what a JR module would expect) and lo & behold it works a treat.  TBH I wouldnt have bought the JR one had I realised HK would be so on-the-ball with the Futaba version, as that suits the project better.

Using an OrangeRx R610 £3 receiver I did a range check and on low power ran out of walking space at 70+ yards.

Best to mention before someone picks up on it, there was a recall of the JR version, it had a timing problem with some frame rates, which gave some elevator jitter, but thats now fixed and all supplied modules were replaced.  Anyone  ordering now will get the revised version. The Futaba version doesnt have the problem.

As yet no-ones sure how they worked out the DSMX protocol, concensus is that they may have snooped a limited number of Spektrum transmitters, and theres concern about GUID uniqueness on DSMX. Consequently people have expressed concern about the 'reset GUID' button and why it should be necessary.  Thing is, certain others have always had GUID reset and no-one has ever mentioned those.  Remember this is for DSMX, when used in DSM2 mode its not a problem.  The self-appointed CE Police are all over it too. Do they check their toaster has a certificate?

Its a cheap option for the S/C project, £18 for the module and £3 for the R610 receivers, and ideal for home brewers, so I'm pleased with it.  I'll report back when the Futaba one arrives, but I expect it will behave identically.
Cheers
Phil

I hope you do full conformance testing before you do ... :P

Well the module is CE-marked and claimed as compatible with all futaba module-based transmitters...

:nananana:

But when I did my Evo/specky switchable hybrid I spent quite a lot of time doing testing in the lab, looking for induced signals on the PCBs and doing frequent memory checks, and if I was going to use this module in a microprocessor-based Tx I'd want to do the same. In a non-microprocessor Tx I'm reasonably comfortable with the idea of just adding a bit of extra decoupling, putting ferrites on the longer internal cables and then just doing static checks.

I'm far from the CE police, but I asked the following on Hobby King's support system .. "Can you confirm whether this module has full CE approval to make it legal for import to and use in Europe? I can see a CE logo on the product photo, but no approval number is shown. Thanks in advance, Tony S"   I asked the question on 7th December, and the only response has been to say my question has been passed to the product specialists.

By the way I also asked for clarification about the GUID change and the risk of conflict with existing Spektrum transmitters, that call got closed unanswered.  I tried three times with the same result.   I guess they don't want to clarify,

Arrived this morning, works great with my encoders, no problems, excellent range, accurate timing, what more can you say?
There is one aspect which will frustrate a lot of Futaba people who buy this to gain access to BNF models -  it doesnt remap as it should. Channels remain in Futaba order - AETR rather than TAER as per Spek/JR.  For me this isnt a problem, but if you cant remap channels within your transmitter then BNFs might not be feasible. Shame, cos uncased and with the buttons shortened, the Futaba-style module would have made a cheap DSM2 hack-module for those BNF's  :af
I feel another recall coming on...  :)

Hi, you said earlier that you already have the JR version, and now you've got the Futaba compatible.   Does your comment mean that the Futaba type would be more suitable for conversion to a hack module, if so then what makes the difference?

Thanks, Tony S

Its smaller, and the connections are conveniently at one end of the pcb Tony, so although you could use either, I think the Futaba version would be more convenient as a hack module.  If you can live with the channel assignments that is!

I got one of these modules for use with a Futaba FF9C in conjunction with the "Orange" 6 ch receivers, the mapping was all wrong and not having failsafe on the throttle made me decide to send mine back today for a refund.

The mapping us not wrong.

It is just passing the data through exactly as your transmitter sends it.

What is different is that spectrum and Futaba use different channel numbers.

Sadly most commercial sets don't allow you to set your own mapping.

Another reason why I like open9x and er9x :-P

Irrespective, the unit was of no use to me. Even if you change all the leads around on the orange receiver so that everything works you will end up having the throttle on the aileron channel for which there is no failsafe.  not a good idea and against CAA/BMFA recommendations.

Fair enough.

I was just pointing out the issue is not the module,  but rather the channel mapping to the module.

Its not even that Rob really, the beef is with the overall system  when using a Futaba-style module, not the JR one which would fit the 9x or any JR and is fine & dandy.
The problem is that the matching OrangeRx receivers have failsafe on channel 1. As you know thats a function of the receiver. The lack of remapping (which is its main difference from a genuine Spektrum DM8) means that Futaba users, ie 99% of the market for this particular version, will have failsafe comprising throttle stays where ever it was (full open?) and a user-selected degree of aileron deflection. When using the OrangeRx Futaba module in a Futaba tx, and an OrangeRx receiver, the most common failsafe outcome will be a high-speed power-on spiral dive, as opposed to the expected power off  and slower arrival.  Thats the concern. 
Some would say that because OrangeRx (and low-end Spekkys) have failsafe hard coded onto channel 1, that swapping servo plugs on the receiver is absolutely not on, and that he fault IS with the module because it is designed for Futaba, which mostly cannot remap at the tx, whilst also being a  member of the OrangeRx DSM2 family, which was designed to follow the Spekky standard of TAER.
In a way you're right, theres nothing fundamentally wrong with the module, it works brilliantly with my stuff. Its the overall system thats not so good for Futaba users, and fixing it would be so easy!
Cheers
Phil

Rob Thomson

I do agree....   And being modular you would think that unfitness a Futaba,  it would send the signal in Futaba channel ordering.

It was this very issue with Jr sets that first got me on to the th9x and custom firmwares.

Oh well...   I have a full 9x with dsm module for use on the few bnf micro models I have -  but as I mainly fly gliders and frsky,  it gets very little use!

I see from this morning's HK bulletin that theres now a cheap way out for "Futaba/OrangeRx module" users who aren't interested in BnF.

(Just to recap, BnF aside, the problem for Futaba users isnt that you have to move plugs around into Futaba channel order - thats easily done. The real problem was that on the cheaper OrangeRx receivers, failsafe is hard-coded onto channel 1, and all other channels stay where they were. This meant that the only failsafe option you had was some aileron deflection and everything else including the throttle would stay where it was when the signal as lost.
Basically all failsafes would end in a power-on spiral dive.
)

The news is that they've just released the cheapy R620 receiver which has failsafe on all channels, so "Futaba/OrangeRx module" users can set failsafe to low throttle on ch3 and surface deflection on the other channels as required.  It doesnt fix the lack of mapping, it doesnt help with any BnF aspirations, and you still have to plug the servos into the R620 in Futaba order, but at least the vital aspect of failsafe has been overcome without having to use expensive rxs.

Presumably it would be possible to hack the module to a Mutlplex transmitter if all that's needed is power and signal to the transmitter module.  Multiplex are quite flexible in channel allocation so it wouldn't be a problem.  Fail-safe is a function of the receiver so that wouldn't be a problem either.  You just need to know/find out which are the pins to use.

As I started out with Futaba transmitters I use their channel allocations on my Mux 3030 just because I was already familiar with them.

I'm sure it would go straight on Geoff. My gear is about as un-JR spec as it could be and it interfaces to both the JR and the Futaba versions just fine.
I use a schottky in the PPM to effectively give an open collector drive, which works fine with either, just like a Frsky DIY, though I havent yet traced the PPM circuitry.  If you dont have a schottky to hand PM your address & I'll send you one FOC.

Thats true, its not a problem as long as you remember that on the cheap receivers, you only get failsafe on channel 1, so you're pretty much forced away from Futaba mapping,  moving throttle to channel 1. The rest dont matter as theres no failsafe on the other channels on the cheapy rxs.  The new rxs have failsafe on all channels so no problem, have the channels in any order you like!
Cheers
Phil

Geoff Sleath

Thanks, Phil.  I was only speaking theoretically as I have a Spektrum DX6i which will satisfy all my BnF applications, I'm sure.  I could possibly find a Shottky diode somewhere as well.  The only receivers I have that offer a fail-safe option do so on all channels - that's FrSky and Mux mostly.

I'm waiting for the new FrSky transmitter to become available when, depending on price, I may well indulge myself particularly if it provides the sort of flexibility that my Mix3030 does.  I suspect I'm not alone :)

ive just had notification that these modules were back in stock so ive ordered one for my FF9. also ordered a 7ch rx and satellite to. these means im now going to have research spektrum stuff!!

The new firmware which remaps the Futaba channel order to TAER is now on HK:
http://www.hobbyking.com/hobbyking/s...uct=38395&pb=1
Remember this is for the OrangeRx Futaba DSM2/DSMX module which as supplied leaves its channels in Futaba order - AETR - which doesnt suit BNF models. This update remaps the Futaba channels to TAER as expected by BNF.  Now the channel mapping is fixed, theres no reason to spend £80 on a Spektrum DM8 module!
Even for those with no interest in BNF, this is a good thing as it puts your throttle on the only OrangeRx receiver channel which has a failsafe - ch1.
On a more trivial level, it also means the receiver label is now correct!

Tony - they've recently released a 'DIY' or 'hack' version:

I received my HK Futaba-Spectrum module today, just 20 minutes after the postman called the module had been re-mapped using the new usb programmer. Brilliant and works a treat on BNF etc.
Well done HK.   :af

(Now I wonder if anyone has a suplus Campac, 64k if possible). I intend to put all myElectric models on the FF9 now.

Hi All,

I've been out of the hobby for a few years, so to ease myself back in I've bought a Parkzone Micro P51 and a Blade Micro heli both of which I fly with the standard Parkzone 2.4 Tx. My question is, would the orange 2.4 module allow me to fly both of these models using my old JR3810 Tx?

I've e-mailed Horizon hobbies and Macgregor but did not receive clear answers and I have to be honest that I'm not really up to speed with the 2.4 stuff.

I'd considered just buying a new Tx but the Orange Module looks the cheaper option,

Thanks all,

Tony

Phil_G

Yes, the channel-mapping 'problem' was related only to the Futaba-fit version of the OrangeRx module. The JR-fit version does not need its mapping changed as the JR encoder generates its channels in the order expected by BNF models.
Cheers
Phil

Cheers Phil, module ordered!! I may be back with some questions in about a week!!

Hi

Anyone know if there's an alternative to the HK programmer, which is on back order ?

Thanks

netdudeuk

I've just downloaded the drivers and can see that they're for the same device that's on this http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130847444988&ssPageName=ADME:L:OU:GB:3160 USB to serial adapter.

I wonder if there's a way to use it for this purpose.

John Evans

Hi
I have purchased a BNF micro Parkzone Corsair. I then purchased what I thought would be the ideal answer to fly with my futabaff 9 transmitter, a Orange 2.4 futaba compatable  transmitter module. On testing the module, it does indeed bind with the model but as I fly on mode 1 the sticks do all the wrong flying surfaces. Any suggestions in plain english would be very welcome.
Regards
John

Rob Thomson

I would just buy a 9xr for £50.

Plug the module in that.  They opentx/er9x firmware on it will enable you to Mao the channels correctly.

Rob, I understood that the 9XR needs a JR module so wouldn't take a Futaba module.  $%&

Sorry to bump an old thread but theres been a poignent reminder on RCG worth repeating here... 
If you use OrangeRx modules alongside other 2.4g equipment like Frsky, Spektrum, etc  remember that where almost everone else uses a male RP-SMA on the module and a female RP-SMA on the aerial, OrangeRx uses a female SMA on the module and a male SMA on the aerial. 
Put simply, the OrangeRx aerial has a pin in the centre, almost everyone else has a socket.  This means its very easy to fit for example a Frsky aerial onto an OrangeRx module - it will apparently fit perfectly, it will screw on nicely, will seat nicely and look perfect. BUT there will be no connection between the module and the aerial - both having the centre socket.  Unless you're very hamfisted and you bend one or both of the pins you cant fit an OrangeRx aerial to (say) a Spektrum/Frsky/Corona module, the pins on both parts prevent you screwing them together.
I'm borrowing a couple of photos from RCG as it illustrates the point perfectly - so credit to the OP over there:

[attachimg=1]

[attachimg=2]

Frsky is the same as Spektrum, I use both so I've been through all my sets and checked.
The reason for posting this reminder is that I found a Frsky antenna on one of my spare, unused OrangeRx modules! 
Bottom line - mixing up Frsky & OrangeRx aerials could be disasterous!

after seeing quite a few good reviews of the Orange modules i thought it would be a good option to use with my new tx for my various indoor models.

great service from HK in getting my order of parts to me, ordered Sunday night from global warehouse and arrived at my door Thursday am. everything else was fine. i took the diy module out of the box to check sizes as i am going to get a small box from maplin to mount it in.

on looking at the module i noticed that there was a wire off the board. i put it down took photos and raised a warranty claim with HK straight away. i then picked up the module went to stick it back in the box and a second wire pinged off the board.

it looks like a very bad soldered joint on all 3 input leads. my soldering isn't perfect but i think i could have done a better job. i am glad that i spotted it now and not installed it only for it to fail at a later stage when it was out of sight in it's box. it could have failed during flight which would have been a disaster.

so a quick word of warning to check your module!
