Help! x7Q and S6R (on explorer) - elevator and rudder sticks/channels move servos differently

[Kilinius]

Hi, I might have a stupid question. I built my first flite test plane - explorer and I put my Frsky S6R reciever in there (i am using Taranis x7q). When I put any servo into the channel used for the elevator and I move the stick up and down (mod 2), the servo goes only like 45 degrees each way. When I put the same servo into the channel used for the rudder and i move the stick sideways the servo moves much further. I tried to play with servo endpoints (travel adjustment), but the servo wont move any further. My elevator does not go up and down enough. I checked and its not a mechanical problem on my plane as when i us the elevator with my rudder stick, the rudder moves much further. Also my stick goes up and down the whole way so I think its not an issue with the x7q hardware.

Any suggestions? Is it a firmware thing? Can you perhaps direct me to a similar thread? Thanks a lot.

Try calibrating the sticks. It’s in the radio menu, couple of pages in.

Thanks for the reply. Thats the first thing I tried. The wierd thing is the difference between the range of the servo angle whe I use the elevator and the rudder stick.

inputs page in the qx7 ??? all out puts at 100 = same output on servo !!
mixes page same thing ...!!

Thanks, but I did that as well and checked many times. I also extended the limits of the servos, but it didnt do anything. I also tried a different servo but when I us the elevator stick it just does not move far enough. I am sure the answer will be so simple but I cant find it.

Have you checked the mechanical movement of the Gimbal? Look inside from the back and see if it moves the same on both axis. It could be a damaged/faulty gimbal too. If settings isnt the problem that only leaves a mechanical issue, since you have tested the mechanical servo linkage then the TX is the only alternate source of a mechanical input limiting the travel. You could swap the modes over so the sticks were different as well, that would allow you to test the gimbal without physically removing it?

I´ve looked inside and everything looked ok to me. But I have not tried the tests suggested by you. I´ll try to switch the mods and see what happens. Thanks a lot guys.

How old is the transmitter?

How old is the transmitter?

A month maybe. I have not fleshed it yet to be honest-still learning.

The gimbal shouldn’t have died in a month. Possible but unlikely. Does it happen on other models?
Have you tried making a whole new model from scratch again? You might have done something minor in setup that will be a pig to find.

I will try that. Thanks.

I had problems with it too.

My plane (reciever) just needed to do self-check now my servo's work almost 180 degrees.
Frsky has limits on rudder movement out of the box.
