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

Is anyone aware of a 3D printed mount for the nano?
What I have been doing is using a bit of velcro on the "shrink wrap" on the nano. but it you have to move it more than once or twice the wrap starts to come loose from the board.

Any suggestions?

I managed to water my remote for the first time in 50 years. Shall happen is fortunately not defective.

As a result, I also immediately got myself a replacement transmitter board. Unfortunately without instructions.
Where would have to plug in the blue plug.

Either as in picture CN1 or picture CN3. This is also the name of the connectors on the board.

The board was in a MC-19, would also be suitable for a MC-22.

Can I reverse servos and adjust throw on the RFU while in S Bus mode?
Thanks!

Question.

Looking at this thread in RCG, https://www.rcgroups.com/forums/showthre...-XG11MV-Tx

I saw this in post numbers 4 and 5

Post number 4 by Antic Bipe
Hi Jim, does the XPS JR 11X module support all 11 channels when using the DSM modulation? Your module will however require an external aerial if used in the XG11MV. 

Post number 5 by you
Yes, it does support all 11 channels.

I am not sure if they use serial (115.2K baud) like some of the DSM modules require, or the manchester encoding that the JR11x uses.


So my question is could install your JR-11X internal module into the XPS-J1 case upgrade w/antenna connector and use that module in the XG11-MV to use it with a RFU or Nano when the XG11MV uses DSM mode?
 
thanks,
Bill

Hello Jim,
I put a Nano on the XDP and this came up in the display.  It says XPS-12T with no firmware version.  The picture is the old 10 channel receiver. See attached.  But when I ran updater60 on it, it showed as Nano-E V4, with a firmware version of 1.0
