Chris Bott - Moderator Posted June 6, 2016 Author Share Posted June 6, 2016 That's a very good point Andy. I'll be most careful to check that. As it doesn't need very much range at all, there will be a way to reduce Rx signal level, I'm sure. Quote Link to comment Share on other sites More sharing options...
Phil Green Posted June 6, 2016 Share Posted June 6, 2016 Both cases posted today chaps. Posted by Andy48 on 06/06/2016 15:20:16: There is a very definite problem with the Taranis Not with the Taranis Andy, but with the module/rx combination. Sorry, there I go again...

Andy48 Posted June 6, 2016 Share Posted June 6, 2016 The examples I gave above were not using the external module, the standard XJT internal module and the X4R or X8R. The receiver transmits at the same strength as the transmitter. Quote Link to comment Share on other sites More sharing options...
Phil Green Posted June 6, 2016 Share Posted June 6, 2016 Ah sorry, this being the "Spektrum module for Taranis" thread I thought we were talking external modules. Yes I've also had the low rssi beeps at extreme close range (inches) but never any unwanted control throws. Could it be that the deflected aileron was an inadvertent failsafe setting? Cheers Phil Quote Link to comment Share on other sites More sharing options...
Andy48 Posted June 6, 2016 Share Posted June 6, 2016 Nope not a chance, as failsafes set on tx. Don't forget it won't bind if too close. I can forsee a problem when pupil and instructor turn towards each other and transmitters are very close, and pupil then loses control without instructor realising what has happened.

Chris Bott - Moderator Posted June 6, 2016 Author Share Posted June 6, 2016 I've certainly had telemetry lost notification when Tx and Rx are too close to each other but I don't think I've ever lost control function. I certainly never ever seen uncommanded surface movements. Quote Link to comment Share on other sites More sharing options...

WolstonFlyer Posted January 29, 2017 Share Posted January 29, 2017 I have one remaining full set of parts to make up a Spektrum module, you will need the RF board from a DX5e and a suitable case such as the DM9 available from here **LINK** I can post the kit inside the UK for £15 , I can't go lower than that because of the cost of the PCB from the USA, the postage was expensive. The kit includes PCB and components to solder on as shown in this picture: After you have soldered it together, the only tricky bit is the 12 pin socket for the RF board where the pins are quite close together, but it's not too hard. Shown here with the RF module plugged in to the socket. Edited By WolstonFlyer on 29/01/2017 22:55:53 Quote Link to comment Share on other sites More sharing options...

Danny Fenton Posted April 16, 2017 Share Posted April 16, 2017 I have a friend that wants to build a module, what's the best source for a board and bits now that Phil has sold the last kit of parts? Cheers Danny Quote Link to comment Share on other sites More sharing options...
Masher Posted April 16, 2017 Share Posted April 16, 2017 Hi Danny I definitely have a board and, maybe, some bits. You can have them if you pm me your address Quote Link to comment Share on other sites More sharing options...

David Patterson 2 Posted January 4, 2018 Share Posted January 4, 2018 Sorry to resurrect this thread again. I've got a related question. I've harvested a module from a DX5e. I'd like to drive it with a micro-controller that generates 22ms PPM. I've proved the concept by playing the PPM signal into the buddy port on a DX6i so I'm confident the PPM generator is sound. I'll like to use a dedicated radio module rather than sticking my buddy switch down with tape each time I want to use the PPM generator. My question is this: how do I put the module into bind mode? Is there a special PPM signal that will do it? Can I wire a circuit with a push button that will force bind mode? If so, could anyone suggest a circuit? Much obliged.

Chris Bott - Moderator Posted January 5, 2018 Author Share Posted January 5, 2018 Hi David and welcome to the forum.I believe that the Spektrum RF module requires a proprietary data stream to drive it, not PPM. This would include the bind command when necessary. OpenTx generates the correct data when a Spektrum module is selected.Unfortunately I've no idea where you'd find details of the required signal, though.

Geoff S Posted January 5, 2018 Share Posted January 5, 2018 I use an Orange plug-in module to fly small indoor models with my Taranis. It was quite inexpensive and I'm happy to use it with models like a Vapor but I'm not sure I'd trust outside with bigger models. Unless you're trying to fit the DX5e to the Taranis as an interesting technical exercise I wouldn't bother and buy a ready to use commercial plug-in like the Orange.

Chris Bott - Moderator Posted January 5, 2018 Author Share Posted January 5, 2018 The advantages of using the Spektrum RF module are outlined in the first post in this thread (from 2014!)But the Orange module does at least accept PPM as it's input.

Mike Blandford Posted January 5, 2018 Share Posted January 5, 2018 It uses serial data at 125000 baud, 1 start bit, 8 data bits, even parity and 2 stop bits. You could have a read of this thread: **LINK** and/or look at the code (open source) for either openTx or ersky9x to see the actual data format. Mike.

flight1 Posted January 6, 2018 Share Posted January 6, 2018 you whant one of the orange modules (JR compatable socket) like this , I have had the older version for a while with no problems this one is more versitile does any DSMX, DSM2 compatible or Walkera (DEVO)compatible receivers Quote Link to comment Share on other sites More sharing options...
David Patterson 2 Posted January 6, 2018 Share Posted January 6, 2018 Thanks Mike. That's really interesting. Not sure why I assumed the RX module was using PPM. I'm using a micro-controller as a USB interface to my DSM radio so I can control the radio from my laptop. The micro-controller is just as capable with regular serial comms so it should be pretty easy to update it to use this protocol. That should reduce latency too which is always good. This has all been prompted by the maaxx-europe.com UAV race that's running in March. I want to fly a racing quad, using the video feed for navigation. I've been able to fly the quad with an xbox remote and I can track the video feed with opencv to follow a line. Not sussed altitude hold yet but that's on the way. Latency is a huge factor in these things so swapping to a quick serial interface could be a big advantage. Cheers Dave P Quote Link to comment Share on other sites More sharing options...
Hulk Goguen Posted July 18, 2019 Share Posted July 18, 2019 Chris i really like how you made your own module. This is far beyond my abilities but i bought a brand new FR-Sky Taranis X9E at a garage sale for $25 and love the look and size of it. I have several Eflite planes with spektrum receivers and want to keep them so i can use the safe feature. I bought the JP 4in1 module but cannot seem to get it to bind to my planes. I followed many online videos and write ups. I have updated the firmware on the radio and on the module and still nothing. I contacted HobbyKing and they have shipped me out a new module. However are you interested in building me a module with the DM9 module? Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted July 18, 2019 Author Share Posted July 18, 2019 Hi Hulk and welcome to the forum. Isn't the DM9 module the old official Spectrum one that if you could get one, would slot straight into your X9E? The downside would be that it's DSM2 only only. I could help with building a module if it's still possible to get a suitable Dx4 as a donor. The important word there is "suitable". I'm not sure I'd know how to recognise the right one now Spectrum have released so many versions of their Transmitters. One of these OrangeRX modules might be your best bet? I have no experience of them but someone else may have? Quote Link to comment Share on other sites More sharing options...
