Stephen Belshaw Posted September 20, 2019 Share Posted September 20, 2019 I've had this new receiver on the shelf for a few months and just got around to using it. I have followed the FrSky instructions (such as they are) and on-line tutorials for binding this Rx which is pretty straightforward: Short signal pins on channels 1 & 2 Connect Rx to battery, red LED lights up Switch on Tx (X9D+), select D8 mode and select bind At this point the red light should flash to indicate that binding has taken place. Mine stays solid red so no bind achieved. I've been round the houses with this and have come to the conclusion that it must be faulty, unless I'm missing something??

Andy Meade Posted September 20, 2019 Share Posted September 20, 2019 Firmware on rx at correct level? i.e. EU LBT? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted September 20, 2019 Share Posted September 20, 2019 Try switching the tx on, selecting D8 mode and bind before powering up the rx, at least that'swhat the instructions say. It's so long since I had a V8R-II that I can't remember now. Quote Link to comment Share on other sites More sharing options...

gangster Posted September 20, 2019 Share Posted September 20, 2019 I cannot remember the details but am pretty sure that rx will bind in two different modes. One of the modes needs the bind plug the other does not. Just check the TX and RX are in the same mode. Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted September 20, 2019 Share Posted September 20, 2019 The V8 series receivers use the old, non-telemetry protocol. I *think* some of the later ones had a degree of D8 compatibility, but it will never have telemetry. IIRC you need to jumper two pins to get it into D8 compatibility mode, so it sounds as if you are on the right track. Certainly that's how you get X-series receivers into D8 mode. However, it might be worth double checking that the receiver really does support D8. If not, you can always plug one of these in the back of a FrSky Tx to get V8 functionality. -- Pete Quote Link to comment Share on other sites More sharing options...
Mike Blandford Posted September 20, 2019 Share Posted September 20, 2019 You are carrying out the correct procedure. Make sure you are using D8 mode on the Tx and not D16 mode with just 8 channels. Mike Quote Link to comment Share on other sites More sharing options...
Stephen Belshaw Posted September 20, 2019 Author Share Posted September 20, 2019 Thanks chaps, I knew it was a bit of a straw clutching exercise and, as I indicated earlier, all the possible options for binding have been tried so it does look like a dud. So back to HobbyKing it goes ........... Edited By Stephen Belshaw on 20/09/2019 17:50:13 Quote Link to comment Share on other sites More sharing options...
PatMc Posted September 20, 2019 Share Posted September 20, 2019 Stephen, are you aware that the V8R4-II is really only safe to use for indoor or "park flyer" type models? Although the range is >1km, having only a single antenna makes it prone to having the signal temporarily blocked in flight by battery, servos etc. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted September 20, 2019 Share Posted September 20, 2019 Pat, I've been using one in my Riot foamie for years with no problem at all and that certainly isn't an indoor model.

Stephen Belshaw Posted September 20, 2019 Author Share Posted September 20, 2019 Pat, yes - I intended to use this for smallish models that I can fly from a field across the road from me. Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted September 20, 2019 Share Posted September 20, 2019 Hi Pat Like Geoff I've been using V8R4-II recerivers in a bunch of models for some years, with no problems - just had a count up and it;s a round dozen models from a diddy Limit EX slope soarer through Speedo, PMP Hawk up to to an Easyglider - they are my small receiver of choice for simple slope models. The RX aerial is diddy, but it seems to do the job okay. I thought for binding you needed to just push the button - there is no binding plug that I'm aware of.

leccyflyer Posted September 20, 2019 Share Posted September 20, 2019 Ah, missed the subtitle - it's a Taranis Tx - I;m using mine with a module, no telemetry required. Quote Link to comment Share on other sites More sharing options...
PatMc Posted September 20, 2019 Share Posted September 20, 2019 Fair enough, Geoff & Leccy. I've been using 2 of V8R4's & a V8R4-II for a few years now without any problems. The V8R4's in a Veron Deacon which is virtually free flight & in a small ultra light HLG, normaly flown as a light wind, close in slope soarer. The V8R4-II is in an X-Kraft, which is fairly fast but is always flown at close range as it's too small to fly at any distance & still be within my eye range. Stephen, I was concerned that you may have intended the Rx for a thermal glider or hot liner & may not have been aware of it's possible limitations.

Bob Cotsford Posted September 21, 2019 Share Posted September 21, 2019 Just a long shot as I'm sure I did it myself - you did remove the shorting link on ch1-2 after binding and before powering up the receiver again?
