Hello Luke
first up I would like to thank you for all your work and the other developers who have made this TCB a success.
I have just started to get into my TCB. The radio I'm using is the new Turnigy 9x AFHDS 2A with the IA8 PPM rx. I have flashed this to the latest version of ER9x and it works ok -- however you won't get any response from tcb when you are in the radio function -- you see the chans but no response. I had to set the PROTOCOL to NEG in the model setting in the 9x radio then it could see the chans responding to input.

My questions is regarding the aux chans 1-4 that I have access to as the radio is only 8 chans.
The radio has 6 two way switches , 1 three way switch and three pots that all have to share the 4 aux channels.  It looks like its a one switch per channel only option which means more than half on my discreet switching/pot options on my radio can't be used unless I upgrade the TX/Rx modules to 16 chan. The latest ER9x software - suppports 16 chans so is this my only option.

I read about the Turrent stick also doubles up as a 9 position switch. Can I used this to set up some mixes on my radio to then assign the unused switches to these 9 positions? How will this impact on the basic turrent functions-- I assume you can't use this 9 positions at the same time that you rotate the turrent/elevate gun etc.

Thanks again
Rockchuck

Rockchuck, thanks for your report on the new Turnigy AFHDS 2A transmitter, I saw they recently released it but you're the first I know to try it. I wonder if the PPM would have worked even without the ER9X software. The other thing you could have tried would have been to connect the receiver to the bottom radio connector on the TCB, yes even though PPM is supposed to go into the top. The bottom connector inverts the signal so it might have worked. But anyway you got it figured out so that's good.

The 9 position switch on the turret stick is a feature built into the TCB and those 9 positions can't be accessed independently by other channels on your transmitter, they are inextricably tied to the two channels of your turret stick. Now I suppose with some rather fancy radio programming you could probably cause other physical switches on your transmitter to actually mix with the turret stick channels such that you virtually create a turret stick movement through another control. Trying to wrap my head around the mixes for this gives me a headache but with ER9X no doubt it is possible somehow.

Either way, yes in fact you can still control the turret with the turret stick even if you use the turret stick triggers. I'm sure you've already read the Wiki page on this, but the way it works is only when you hold your turret stick all the way to some corner or edge does the trigger occur, but regular turret stick movements not quite to the edge operates the turret normally. In practice it is hard to actually get 9 switches out of it, realistically it works best when you keep it to 4 (either the 4 corners or the 4 edges, you can do both corners and edges but often you will trip the wrong one by accident).

I would give the turret stick triggers a try just to see what you think, it's very similar to how Tamiya and other aftermarket boards work. Even if you only use 4 of them plus the 4 extra channels you already have that gives you 8 triggers to play with.

If you can swing the extra expense an FrSky XJT module and receiver is a good investment and then you are free to use all 16 channels. The good thing about getting a module transmitter such as you have done is that you can always do that upgrade later.

Thanks Luke for your reply.
I did try the Turnigy 9x AFHDS 2A radio with the stock firmware but it was very hard to navigate around the different menus. I did have it communicate with the TCB and when I used the radio commands test in OP the chans did show up and they did respond to stick moments but they seemed very jittery.

Anyhow I couldn't live with the stock firmware in the radio so flashed it to ER9X -- a lot easier to navigate and the response through the tcb in the Radio mode look very stable and no jitters.

I have been looking at the FrSky module you mentioned but they are aud $100 and I have to get them from the HK Global warehouse-- which has very high shipping costs to Australia. I only paid aud $62 for the new 9x as HK had a sale on that's why I bought it-- you can't beat that price for the amount of functions you get in the radio.

However the new 9x radio may look like it is a modular construction for the transmitter unit in the back - which gives the impression you can just swap it out with the FrSky BUT they have the same installation as the older 9X units in that the coax cable from the aerial is run into the Tx module and soldered onto the cct board.

So you would have to do the Tx module hack to fit another Tx unit.

I will try the radio mixer options to see if I can get them to work with the TCB turret stick commands. I have other control units like rcta ASP and a Elmod so I want to keep the radio stick moments and switch functions the same on the different platforms if I can, otherwise I will have to have an instruction manual taped to the different radios so I know what switch etc to use.

Looking forward to the Sound Modules becoming available.
cheers

This is all very good information about this transmitter. The 9x has been out for so many years now and has been so popular you'd think some manufacturer would finally just release a version of it that got everything right, but they never quite get there...

I definitely know what you mean about needing instruction manuals for each model... Good luck and keep us posted on your progress.

Hello,
The Turnigy 9x can be used out of the box with the TCB, ELMOD, Clark and all other availaible control boards.
The output functions must be assigned in the menu Model - that's all.

The Turnigy 9x is the most modded transmitter i know, look at here:

The Turnigy 9x can be used out of the box with the TCB, ELMOD, Clark and all other availaible control boards.

Actually until last month this was only true of the Clark, Elmod and others, but not the TCB. The problem was that there was no PPM receiver available for the stock module that comes with the 9X, and the TCB requires at least PPM. But just last month they released the new AFHDS 2A version that comes with a PPM receiver, so now it can be used out of the box.

Of course you could always change the module and use an aftermarket receiver with the TCB, but that is not quite "out of the box"...

Anyway, this is just splitting hairs. I love the 9X and have several of them, including a 9Xtreme version I have modified to have 20 physical controls. I prefer it even to my Taranis which cost a lot more but gathers dust!

Hey Luke,
let us split some Hair:
My comment is related to the actual Turnigy 9x......   

In my Th9x is the AR9x board, with XJT Module and Taranis Hall Effect Gimbals.
I use this Radio only for testing and my Wife for her Panzer III.
For my Collection of Panthers and the Jagdtiger i use a Tranis X9D+ Special or my very new X9E.

Small offtopic here: I am another proud user of a heavily modified 9x with 9xtreme among a bunch of other mods, and sometimes I wonder if it would not have been better to just buy a Taranis and saving so much headache and pain modifying the radio... But then sometimes I read comments like yours and I am happy to take the mod way. Or at least I say that to me, lol.

I think I have seen your radio in a video, and it had taranis gimbals and sliders and some more mods. Maybe you can open a thread showing what you did... And I might copy something if there is still room and options in my radio.

Also I installed a multiprotocol module but I have not tested it yet. What receiver would you recommend me for the open panzer board, as cheap as possible but with battery telemetry? (yep, I have read the modules wiki, but considering I have the multiprotocol module you might have a something in mind)

Price for the module is important, I still have to save some funds for buying an open panzer board for myself...

[LukeZ]

Hi Rad, my apologies for never replying to this (I violated my own rule and wrote you via PM!)

The Multiprotocol module allows telemetry with some receivers but depending on what you have done to your 9X you may need to modify the 9X itself so that telemetry data is fed back to the processor, you can find more information on this page of the Multiprotocol GitHub.

The Multiprocol is compatible with FrSky D-Series receivers so one that I like would be the D4R-II and it does have telemetry. Connect it to the PPM port on the TCB and you will get 8 channels (yes, even though it is called a 4-channel radio).

If you want to get 16 channels you would need to move up to the FrSky X-Series and I don't believe Multiprotocol supports that. As I suggested before, my preference is the XJT module (will fit your 9x, or any future Taranis/Qx7/etc...). Then you have many choices for X-Series receivers but I like the X4R-SB which also has telemetry.

You are right about my 9x, it has shown up in some videos. If I get some time I might take some pictures of it, but this thread by João over on OpenRCForums was my inspiration, I did most of the mods he details although I used higher quality buttons on the back of my case and also some rocker switches in the back as well. Of course many of these mods assume a 9Xtreme board which are no longer produced. I can't remember if it is possible to add extra channels to the stock 9X board, but I think not.

[Rad_Schuhart]

That Joao thread has been a lot of inspiration for a lot of people, including mself, lol. He also helped me a lot when I had problems.

I installed a 9xtreme (Hope it is produced again, but it looks like it is sadly gone forever...)
I did the reverse polarity battery mod,
The PPM protection mod.
Replaced all the 2 pos switches with 3 pos ones.
Replaced a pot with a 6 pos switch (One of the best mods ever!)
Installed a multiprotocol module inside, and I can update it with the 9xtreme.

And as far as I know, yes, it works with 16 ch receivers, and also the telemetry wires are connected to the 9xtreme, so it should work. The only thing I have to buy is the receiver, and Ill probarbly buy the one you told me... But I have also seen this one, which is cheaper and smaller:

I think it might be a good receiver too...

About adding more channels with a 9x... Well, I have seen some threads of people that added another extra 8 channels installing another stock module inside... But flashing er9x is mandatory.

[LukeZ]

Rad, that's an FrSky X-series receiver and to my knowledge the Multiprotocol module is only compatible with FrSky D-series. I could be wrong but that's my understanding and that's what Multiprotocol documentation shows.

Your 9Xtreme board can certainly handle 16 channels, but the limitation in your system is your Multiprotocol module, which was designed primarily to control cheap toy-grade quads that don't use many channels. FrSky D-Series is capped at 8 channels, you would need to upgrade to an XJT module in order to use X-Series receivers and thus all 16 channels.

Uh, oh... I hope you are wrong, because if not, I bought the module for nothing...

And according to the link you provided....


FRSKYV = FrSky 1 way - 25
Models: FrSky receivers V8R4, V8R7 and V8FR.

FRSKYD - 3
Models: FrSky receivers D4R and D8R. DIY RX-F801 and RX-F802 receivers. Also known as D8.




FRSKYX - 15
Models: FrSky receivers X4R, X6R and X8R. Also known as D16.

Extended limits and failsafe supported

Telemetry enabled for A1 (RxBatt), A2, RSSI, TSSI and Hub

Option for this protocol is fine frequency tuning. This value is different for each Module. To determine this value:

find a value where the RX accepts to bind. A good start is to use one of these values -40, 0 and 40.
find the values min/max where the RX loses connection. In serial mode you can change the value and see the effect live.
set the value to half way between min and max.
video showing the process
Sub_protocol CH_16 - 0
FCC protocol 16 channels @18ms



So I think it should work. Doesn't it?

[jhamm]

Hi Rad,
you need Firmware V1.1.6
My Module is V1.1.5 and could not bind with X8R!
Try all things what possible -different Firmware with and without LBT - no chance.
Have actual no time for modify the Module with soldering in pins for Firmwareupgrade....
