nws is nosewheel steering, I use the rudder stick trim to trim the nosewheel and disable the trim for the rudder itself, as normally jets do not need rudder trim.

some use the trim in fast mode, but I never liked it.. I can find the kill switch quickly in the heat of the battle.. I had to kill a gasser last week using it and do an emergency landing when something broke.

It's not problematic, just unnecessary. You only need hi and low with nothing in between. My trim was set to 100% step with one click on and one click off so I finally just moved it to a two position on off locking switch.

Enjoying this thread to learn more about the Jeti system...
I think the JR guys have the throttle trim idea right .. it's the only analog trim on the TX so its position can be seen visually. I emulate that on an 18MZ by using the slider next to the throttle as the throttle trim. Perhaps the same technique would be useful on the Jeti system.

I use the rudder trim only for nose wheel trim. I have never trimmed the rudder of a jet in flight. Now I need to find a use for the throttle trim. Gyro gain maybe? Unlike a knob it can be a different value for each plane without worrying about moving it.

For first time we can finally show the Jeti DS-24 Standard transmitter. As you can see we have new sliders and all buttons on the front are polished.

Once I looked at the functions I had available and took advantage of them and stopped trying to make the digital throttle trim act like my JR12X analog trim I was much happier, So much so I would never go back to an analog throttle trim again..

I would definitely want throttle trim on a glow engine if I flew them, which I don't. I'll keep it for a gasser too along with the kill switch. But for a turbine there is no need at all.

I second what wayne and bob say here. Throttle trim is only used to trim a motor idle up and down. The kill switch I use is the locking type. It also closes the throttle on a glow. It kills the ignition on a gasser. It locks the throttle on an electric and kills the turbine. On a glider it raises the spoilers with the throttle back in crow or if it has a power plant it kills it. I Don't do Helicopters. It arms my quad motors too. Fwiw

To have the steering disable I just did a mix, select the gear switch, when down it apply the mix at 100% up it disable that mix. Need to switch out of global
I also have another mix that give me more nose wheel steering throw with the flaps up...for taxing, Flap to takeoff/landing give me less so it's not too sensitive, my flaps/cruise is also my flight modes.....

as mentioned just assign your NWS to the rudder trim, create a rudder to NWS steering mix with the gear switch as your on/off switch. in dual rates you will see your NWS. Using the spring loaded switch to control your dual rate, set it up so when you pull the switch you get a high rate for steering on the ground, when you release the switch have it go to your low T/O rate that way you can never forget and over control your steering during T/O!

I have also experimented with expo on my NWS too.. not sure I like it, when you hit the second part of the curve.. giddy up.. but it works

Thanks Dansy and everybody else for those suggestions. I had messed with Digital Trim before (without success) and just now figured out that the little icons under the "Trim" column represent the trim control buttons (and their location on the TX) and the "Function" is what is actually being trimmed. Got it through my thick head that "Rudder" trim can be assigned to other controls and referred to as such in the Function column. I'm slow but trainable.

Question about servo balance?
So my nose wheel steering was set up perfect and next day noticed steering way off, thought maybe I jumped a spline on servo arm so took off arm but OK.
Then noticed under servo setup my nose wheel steering that despite subttrim at 0 the servo balancer is showing 50% which limits steering in one direction. I do not have a knob assigned to nose wheel steering as the jet tracks dead straight.
How do I get this servo balancer back to 0 so I can get full direction in the other direction. The CLR or auto buttons not affecting the setting
Thanks
Roy

By the way I did watch the esprit you tube video on servo setup and balancer and with the rudder stick can move it to 0 on the servo balancer but it does not lock there and keeps going back to 50

Is this a new problem with an old setup or is this a new setup ? Did you implement steering with a mix or simply assign the steering function to your rudder stick ? If a mix is it controlled by a switch ? If so, is it a 2 or 3 position switch and how is it defined ?(on/off check mark,, proportional +/-100, etc) Do you have a function curve assigned to the steering function ?
