Firstly, no problems with XPS 2.4 module with any Rx.
Or a well known European dedicated 2.4 brand flying concurrently.

Maybe we can get a view from your knowledge.

This is out of the ballpark, but some are having trouble with loss of signal to Rx on Tx16S internal configuration.
Total loss of control and spiral in from level flight. Failsafe set on one occasion only, so doesn't seem a factor.
Doubtful that the Tx is a problem, common to 3 different Tx's.
Just who is using our R/C bandwidth? Everything from toys to licensed UAV. 
Increasing 2.4 activity in a rural zone, farming, water control, etc, etc.

Possible causes, band width, batteries.

1. Batteries are a well known make, A123 type with internal charge control, not dual, load test OK after crash.
2. Many flights successful prior to crashes.
3. Postulated that 2.4 is becoming overused, and users are running out of band wriggle room. 

So, do you have any views on producing dual band 2.4/9 mHz or just 9 mHz to improve the odds.
Or is this dual band idea just a blind alley, down which we don't need to go?

Hi,

Need more channels.
Radiomaster TX16S in XJT can output 16 channels.
J1 Module handles this, that's great.
Radiomaster TX16S in PPM can output 16 channels.
Recall that the J1 Module will only handle 8 Channels. 
To refresh my memory is this correct?
I can't find a reference to it, time to update notes.

Regards,

Trying to find a use for a good JR11xZero.
I need 10ch to an X10/16, but as I understand only 9ch can be output from the current JR module using PPM9.
10ch can be output using SPCM, but the according to the doco the module can not handle the modulation.
Was ever an upgrade done to enable this?
Also does the RFU accept SPCM?
Assumed that Nano's won't.

Rather think that this may be the end of the road for my JR Tx, but modules work well in Taranis/Radiomaster.
Seems like Tx modules might be a dying breed


Regards,

Apologies if this has been asked and answered but I didn't see it here.

The new FrSky X20 series of radios did away with the JR module bay and now have what they call a "Lite" module bay which is smaller.

I am currently using an X10S with your JR module and Nano's for receivers in it, but I'm locked out of that arrangement with my new X20S.

Does XPS have any plans for a TX module that will fit the Lite module bay of the X20S?

Good day everyone and Jim, I'm happy to be back here. I have been flying a lot though. Been practicing the P23 pattern schedule as much possible. 
Please advise if xps have an internal module for a JR XG8 TX. I don't have a XG8. I'm asking for a friend who is having problems with some sort of lockout issues. 
. I also see that the XG8 TX battery is only a 2 cell life. Seems od to me that a TX would use such a low voltage.?

Many thanks all.

Jim,

I configured a DragonLink receiver to output SBUS and connected it to an X10.

The system connects, but the LED on the X10 flickers steadily at a fast rate, something 10 per second, maybe faster.

A servo connected to the X10 moves as expected on the correct channel, but it moves in a slightly "ratchety" fashion.

Any ideas?  I tried inverted SBUS on the X10 but it did not connect at all.

Thanks,

Paul

Jim,

I hope you and your family are well.

I am setting up an old quadcopter that requires a PPM input to the flight controller.  I flew the thing about five years using a Nano Rx configured to output PPM on pin 2.  At that time I used a Futaba 9C transmitter with your XPS Futaba 9C Tx module.

Now I want to fly it with an OpenTx transmitter.  I have your JR type Tx module in the Jumper T12 and I use it frequently to fly models equipped with XPS receivers - no problems.

However, I am unable to make the Nano output PPM using the Jumper T12 and XPS JR Tx module.

My gut feeling says that the transmitter and XPS JR Tx module should not care how the Nano outputs the servo signal, whether it be PWM or PPM.  It worked when set for PWM and I was able to drive a servo directly.  But when I re-binded it and changed the output from PWM to PPM (led "solid on"), I could not get an output.

Can you think of anything I am not taking into consideration?

Thanks,

Paul

So I went to bind a New RFU to my TX and when I pushed the program button after the light started flashing...........it went dark and never turned orange and never turned green.  For the heck of it, I went ahead and tried to bind it to my TX when there was no light and my TX turned green like it binded.  Is my RFU bad since there is no green light?

Jim, I have 2 nano's that are acting weird.  One is used, the other looked to be new.
I bound them following the procedure power on the nano, bind plug on then removed, power on TX holding the PROG button, release the button and they bind.  Power off both, then restart.  The TX rapid flashes green, the RX is steady red.

None of the controls work, regardless of which port I plug a servo in.  True for both RX.

Same TX on a previously bound model and it works fine

I followed the same procedure with another TX with the same results.

I don't want to return the RX because as I understand it you replace them without trying to fix them and you are out of them at present.

Advice. suggestions?

Thanks
Jeff

Jim
Top of the Morning to you Sir. Do you have an estimate on when the Nano's will be available? I need 4 or 5 of them.
Thanks
