Odd behaviour from models.
« on: May 16, 2018, 17:27:52 »
Hello guys, i`m getting an odd behaviour from my models and I think it may be down to my taranis.
I seem to have all axis correct, models fly great ant then suddenly they seem to swap directions on the axis mid flight causing a crash.
I`m not 100% certain this is the transmitter causing the issue but as it is with all models it seems to point that way. Anybody had this issue and know a fix?

You say models, do you mean multi-rotors or planes or helicopters?

That's a strange issue especially as it happens across all you different set ups for different craft.  The only thing that would cause that IF you Taranis was working properly would be that you might have a different input or mix selected when you move a switch assigned to a different input or mix.  Easily done. 

The last helicopter I set up had that when I selected different rates and the input was changed to being reversed.  Its unlikely that all your models would have that same error.

Do all the axis change or just one axis?

I would say it might be a loose connection on your stick pots or sensors, especially if it's just one axis.

It would be tricky to check a multi rotor but with servos you could try to open up the Taranis and gently fiddle with the wires going to the stick sensors and see if any servos jump as the connections go wonky.

multi rotors mate, my eachine wizard x220, my sons eachine wizard x220 and my qx95 is what I have experienced it on so far.  modes and switches are not being altered mid flight. I know its odd, It has me baffled. It seems to be on the pitch and roll axis.

Strange indeed.  A loose flight controller board might well do this but again not on all your craft.  Can you look at what the flight controllers are seeing as inputs from your receiver through betaflight or clean flight or something?

See if anything jumps about unexpectedly as you move the sticks.

Original Gimbals or Hall Effect?

Original but relatively new with very light use.
I think I may be getting to the bottom of it, and i think it may be more to do with the settings in betaflight.

Just to update you on this and prove what a silly sausage I am, I found the actual cause, it was something so simple and down to user error.
 I only went and had headless mode activated on mine and my sons quad, i copied the settings over to his. This also led me to believe I was having range issues where I posted in a later thread. So when i was flying in fpv, i would get so far out, do a turn and orientation was reversed and so were my inputs causing a complete loss of control.
 All fixed now  ::) :beer2:

Well done for finding the issue and posting the solution.
It's funny how easy it is to get a setting wrong and the effect it can have....

Happy Flying.
