Default Radioking TX18S and its compatriots - Monitor function fault ?

I have noted a strange Monitor fault ... checking models have no such twitch of surface - but monitor shows stick ineraction ...

Anyone with MPM radio - can they check to see if they have same ?

Do you have a mix or special function somewhere that you've checked as global? I have a couple (volume, timer reset) but I really don't like to use them as they affect all models.

I never set or use any globals .... but that was a thought and I could not find any extra setting etc. ....

I was finishing setup of my Sport Jet and that DID have twitch of elevator servo when throttle operated ... so it is in fact affecting elevator function ...

You say the problem is there on a newly setup model?. Try setting up the model from scratch if you typically use a template model (with all your controls, functions, and logical switches) to start with.

Can you move ELE to another channel, and something like RUD to channel 2 and see if it follows the elevator or stays on channel 2. The question is: is it linked to an input (ELE) or output (channel 2). Depending on what you find, you can look for a stray mix or special or logical function. Make sure you check ALL the channels and functions. I've inadvertently moved a mix to channel 64. Maybe there is something that was mistakenly copied into one of those high channels...

If you still have the problem, I think what I would do is backup all the models, delete them from the radio, and then set up the radio like it was new. Redo all your calibrations and start fresh with one simple model and see if you can recreate the problem.

I think I see it on the 'new model' as I have a trick of marking spline of servo when installing to check rotation - before fitting arm. I put a touch of black marker on the spline.

Its likely that I did not see any movement on other models - but probably there.

I've moved ch's .. functions .... you name it ... but it still occurs ... whatever ch is set to elevator - there it is ...

OK today ....

I've really been delving into my radio ....

Reset radio with clean SD card ... OTX 2.3.15 ..... no models / no scripts etc. Radio was already flashed with AETR FW correctly .. but re-installed

Installed EDGETX 2.8 .... clean

EdgeTX 2.8 with models etc from OTX SD card ..

Tried all sorts - in fact was afraid I was going to brick the radio ....

Conclusion :

1. It must be a hardware problem as it didn't matter what FW ... problem remained

2. Being used to OTX ... I found EDGETX annoying ....

I will wait arrival of my new Throttle gimbal ... install and see what happens. If no joy - then I may look at replacing with the RadioMaster vers2 ......

That is weird.

One last thing to try. I don't have a Radiomaster but on Taranis with OTX, on the hardware page there is a debug=>analogs option that will give the raw output of the sticks, pots and sliders. See if there is something similar on the Radiomaster. When you move the throttle you should see that change but nothing else. If the elevator stick doesn't change then it would seem like a software problem. If it does, then it's in the radio itself.

Does the Radiomaster have a factory reset? Have you tried that, not just a firmware reinstall?

Its a Radioking .... (Jumper made them for a while .. then stopped).

Yes I've been on the raw output page ... and its hard to to tell ...... but it appears not to be evident there.

Yes the RK has two Resets ... partial to remove bad model programming and full reset to return radio to factory status. I've done the partial ... no change ... bit reluctant to hit the full reset as there are so many models on it !

Tomorrow - I plan to delve more .......

Today I got 'p......... off' with it ...

Took back of radio ... took out both gimbals ..... magnifying glass inspected all .... couldn't see anything chafed or wrong ....

Took hint from a previous reply and swapped them over ... they won't fit in the mounts though as the tension parts are 180deg and hit the sliders ....
Switched on ... BINGO !! No errors at all .....

Put all back together ..... closed up .... switched on ... NO ERRORS at all .....

I noticed one thing .... doing calibration again ... ALL centres then zero ... which was not as before ...
Also letting go sticks - zeros were precise and no 'flypast' ....

NOW I'M HAPPY !!

Well, that is good news! Fine start to a new year

Many times, with things electronic, just reseating all the connectors fixes problems.

The fact that your calibration apparently shifted since new indicates that something changed on the hardware side.
