Because someone might want frsky as their main system and use also other protocols externally. That's my reason, I use Frsky for aircraft, then I have a DSM module and a Flysky one for indoor/parkfly models (where full range an proper antenna isn't needed). I like to minimise module plugging, so pr...

I presume the external connection supports PXX as well?

Those weren't available at the time, but the standard whisker Rx antenna gives enough range for my use.

You mentioned internal module... of course you can install a DHT inside the 9X and a XJT or DJT on the outside. Cheers. I have a DHT internally at the moment, the module bay being used for different non-Frsky radios with a switch to select between them. On the 9Xtreme that's supported with soft swi...

I use the older Orange module and I fitted an Frsky receiver antenna on to it in place of the awkward sticking out original one.

Hi,

I know that Frsky don't make an X series hack module, there's no XHT. However I wondered whether anyone had taken an XJT to bits and used it in that way. I'd be interested in how it worked out.

I should add that what I'd really like to understand is the integration between radio and module, does the Taranis do anything that the 9Xtreme+XJT doesn't do?

Hi, Sorry if this one's been done to death, but I'm trying to choose between adding the 9Xtreme board into my 9X, vs buying a new Taranis. If I go the 9Xtreme route, with an XJT module, will I be giving up any function over the Taranis with it's built-in module? The functions I'm interested in are ....

Thanks, I'll have a read through that. As I say I can't remember why I switched from ER9X to Open9x in the first place. Where I'm at just now is that I'm wondering whether to go for the 9Xtreme upgrade (which I think is supported only by ER9X) or for the Taranis (supported by both?)

I was thinking of posting something along the lines of this original question. However now that someone's already done so, would this be the correct place to ask what the key differences are between OpenTX and the ER9X family? I started on ER9X (on a 9X), and swapped quite a long time ago to Open9x ...

Thank, got it. FYI the installer didn't create any desktop icons for me, not for either.

Hi, This is such a basic question I'm sure I must be missing something. Everything I've looked at points to the same place for ER9X and all it's derivatives ( http://www.er9x.com ). On that page there are all the firmware versions, both ER9X and ERSKY9X for different hardware. Down the bottom there ...

I use the original Turnigy v2 module to control a Heliguy "Atom" helicopter (same model sold as Xieda 9958 and HK190).

Hi all...does some of you guys uses 2 tx modules on your transmitter ? I do. Internal Frsky DHT module uses the antenna on the top of the case. A DPDT switch on the back switches power and PPM between the DHT and the module connector, so by flipping the switch I can control my Blade heli using the ...

Thanks, that's a nice way of summarising it.

Perfect thanks, it's so simple I can't understand why I was having trouble. I can put this directly into the control mix, as follows .... CH02 (+100%) Ele * (+50%) P1 Switch(ELE) noTrim Offset (100%) I don't think in this case it particularly helps to use a virtual channel, although this works as we...

Hi, Is there a way to set one of the Pots to provide positive values only to a mix? I want to use the pot to scale some outputs using a Multiply mix, but I don't want negative values that would reverse the control. Ideally I'd want fully anticlockwise to be 0 and fully clockwise to be 100%. Thanks, ...

Or a boat or car where -100% is full power backwards.

Thanks guys, I was sure there was an answer.

Hi, I like the TH% timer for electric models, where the power drawn relates to the amount of throttle used. However that relationship doesn't always hold. Is it possible to relate the timer to any other channel? An example might be where you have forward/reverse so that throttle in the middle is act...

It still occasionally gives a brief kick of power, but I think this may be something else maybe related to that receiver. Firstly because it seems to be only once in every four or five tests, and secondly when it does so the receiver goes into bind mode briefly. I will check with another receiver wh...

Bertrand.

That's brilliant. Thanks for all the work you've put in.

... I'll have a look at the first frame open9x sends, in case there's been an unwanted change and the first frame is incomplete. Hi, did you manage to take a look at that first frame? My setup definitely suffers from an initial kick of throttle, but I am assuming my module isn't one of these later ...

Thanks. Time to get it ordered I think.

Sorry for a basic question, but to use this board do you select the Frsky version of Open9X or er9X, or does it need a special version? I'm not clear whether this board does the "pin swapping" needed by the normal DIY Frsky mod, or whether it makes it unnecessary by passing the data via a ...

The springs and pads were left over from the FM & PCM 72 MHz or what ever non 2.4 tx system was used. It's part of the antenna counterpoise (ground) system. Cheers, I find they get in the way when I'm routing cables etc to keep them clear of the gimbals. I think I'll remove them next time I'm i...

Hi, Inside the 9x there are two sprung metal paddles coming from the front of the set and landing on copper pads on the back circuit board. I don't have a photo showing the springs, but the pads are visible here either side of the DHT ... http://i42.photobucket.com/albums/e320/GandyGoose/RC/IMG_0958...

That's one of the basic rules of RC..

I don't dismiss the fault that easily. (Edit : the serious fault looks to be with the module, rather than with Open9x itself)

Now... To my knowledge - the higher the DBI the more range, but the lower the signal density. The result being that increasing DBI does not necessarily mean better signal. More often than not higher gain requires high directionality, meaning that you need to point the antenna at the model at all ti...
