Jeti DS-16 with spirit Pro.
Have all collective servos working properly with Jeti R3 Ex Bus receiver.
Diagnostic screen shows on rudder channel with rudder stick centered -50%
Rudder stick deflected to left is -100 with servo setup in radio set to -50% max negative max pos and neg limits set to 150+-.
Rudder stick deflected to right is +50% on diagnostic screen

With max positive set on servo setup of 150%, can only get 89% on diagnostic screen.

How do I solve this problem?

If you are sure you don't have any trimming in your TX, try it again with a new fresh Model if you have used a copy from a other Model.

Hello,

did you tried to restart the unit?
I also recommend default channel mapping in the unit and also in the Jeti transmitter (from 1 to 6, or 1-7 with bank switching)
Probably it is changed in some way.

Yes I did try restart several times.

Yes I did notice that the unit would not accept my channel mapping.

The only way I could get it to work properly was letting the jeti mapp the channels by auto. Pitch channel would be on rudder if i used my mapping. Very weird considering I thought that the jeti allowed complete re-arrangement of channel assignments without any conflicts. I guess I was wrong.

Regarding trim control, and sub trims: I absolutely thought that was the case, and verified no trim input. As a matter of fact, when you adjust trim control, you are able to get the 100% where I was suppose to be getting it. But obviously this is not an acceptable work around.

I will try a model copy, but I am concerned that a model would become corrupted like this, as a brand new model. Reason why I purchased the jeti, was not to have the problems of the other cheaper radios.

I will try again today and see if I have any success.

It should work out of the box with default channel mapping.
If not, then it might be caused by a different Mode - Jeti is changing channel mapping demending on this.
But you can easily change it in the menu, so it will match with Spirit.
With Jeti you can set anything, so there shouldn't be any problem.

It should be:
1. Motor
2. Aileron
3. Elevator
4. Collective
5. Rudder
6. Gyro Gain
7. Bank Switching

I turned everything on, now have full throw on rudder. Apparently some power off for an extended time re-initializing was necessary.

Now I can move forward with the rest.
