Hi, Please Ignore the earlier image with In and Out SBus this is not Incorrect. The single connection is correct for custom Fail safe to work correctly. The 2.5 is a typo should be on picture 2.4 !

Hi, Just tried this PMU update https://www.frsky-rc.com/taranis-x-lite-pro/ FIRMWARE - ISRM RF Module - 2019-06-05 ISRM v1.1.2 - * Please do PMU updates ONLY for the radios which has the external power management issue . Its a firmware module on its own. Unfortunately it doesnt work for Horus Expres...

Hi, I now know what is happening with the failsafe. This is for two receivers on different frequencies with one receiver as master with servos and the other as slave with sbus out. When you first apply one receiver failsafe settings the Horus automatically appliess the same setting to the second rec...

Hi,
Thank you, It is a Horus X10 Express I am using?

I have re installed all updates incase an error on my side loading but same results.
So I have posted this on GitHub. If someone elses could post their experience!
I cant be the only person using dual frequency for a backup receiver.
Thank you

Hi, Yes I did post a while back and I followed your advice contacted Frsky repeatedly.
Never received any responce, thought I would remind again for others buying Horus.
Thank you

Hi, It would be really useful if FRSKY/Those in the Know, could implement a PMU update for the R9M 2019 Module so the R9 module stays off when battery charging via transmitter plug. It really isn't helpfull to be removing Li-Ions from the back of TX to charge, whats the point if you can charge withi...

Hi,
Just updated openTX to 2.3.14 Isrm to V2.1.6 and receivers to latest firmware R9SX & RX4R only to find Failsafe no longer works with two receivers.
If I turn of either module all works ok on one RX.
Any ideas ?

Hi, If you select the rx you want to asign before bindingits handy! especially when using two frequencies 2.4 and 900mhz

Many thanks for that not tried my R8 Pro yet!

Are you connecting the TX correctly with two outer trims pushed inwards and power on Tx then connect to software!
Else try the following link to bottomof page http://www.open-tx.org/downloads

Hope this gets looked into,I also received spurious sensor data.

Can you please explain further?

Hi, You need to update the firmware for the receiver firmware to D16 ACCST and select same in TX to bind.

Hope this is helpfull but its the only way I find it works perfectly. Provides the dual redundancy with the sbus/pwm converter working fine. For extra safety cross the plane functions on each receiver such as left Aileron on Ch1 RX 1 Right Aileron CH2 on RX2. Same for Elevator other channels dont bo...

Yes, thank you. In addition I have raised a question with Frsky regarding the R9 2019 Module (R92019M) in that after using an external battery connected to the R92019M (2s Li-ions) I a have been experiencing issues with the registered R9 receivers no longer binding just flashing fast red led even af...

If anyone can shed any additional info on the process, hope this helps. Using a Horus x10 express and mixing frequencies for redundancy with the R9 Module and 2.4ghz receivers, I have found the following: The R9 Stab receiver only has sbus out so make this reciever with telemetry active or not? and ...

Hi, Thanks, contacted Frsky immediately you osted but still no reply. If anyone else with the same issue please post here! Additionally, I wonder if Frsky thought it out regarding the additional power supply for the R9 2019 module ie where are we supposed to add a 2s battery without messing up the r...

Ok, thank you.

Sorry, Horus x10 Express (Access LBT.)

R9M 2019 Access Firmware: V1.3.0
Tx : 2019-09-30 FrOS v2.0.02 Beta (udated Tx too OpenTx 2.3.9)
Iram: 2020-04-21 ISRM v2.1.0

Thank you

After the 2.3.9 update found that I am jo longer able to "backup radio or "backup from file to radio". In addition when I selected the new firmware update no automatic TX backup was performed, with the option selected for such in settings.
Maybe my software or not?
Thank you

Is there any way to stop the R9M 2019 module coming on when charging Horus x10Express with USB lead even when module is selected to off in TX?
Thank you

Just an advisory I received from Frsky. I thought maybe helpfull. The Archer Access G8 is not advisable for use with ignition engines (the product description doesnt say so) R8-Pro and R10-Pro best! The 40cm dipole antennas are ok for use with the new Access RX4R & RX6R but check connections fir...

Hi, Hope I can ask this here!
I have an upgrade receiver (Rx6R) can I use the Frsky 40cm (same fitting) dipole antennas in my packed model instead of the supplied access Rx6R antennas ie any benefit or maybe issues?
Thank you

Hi, Your totally right (of course) for some reason ( me of course) Within the special fuctions volume for S2 is ticked, this would be for volume control via the pot and elsewhere i must have the pot to off, explains why a new model plays the sound. Corrected: Sys: Hardware - S2- pot with detent MDL:...

This may give a better idea (sorry new to this) I tried Horus menus, system - sd card - play a given sound with the problem models and no sounds.
Then repeated same with a new model (without creating any Switched.sounds) and the Horus plays any sound file from above location?

Thank you, not sure why a new model would be ok with sound if it was global?

Could it be anything to do with Horus requiring a refence to the sound file listings in the System/en-US-taranis.csv file ie. I would have to label all additional sound files I add?

Hi, Please can you advise, as above I went straight from fros to 2.3.7 with New Horus x10express. All was working well until (coincidentally) I put a access recever into model and the sound files stopped working. I then tried with another receiver on an imported model settings from Taranis (all was ...

Hi, many thanks you actually meant the term 'value' and not as I was interpreting as an expression!
All working now.
