4WS Setup Issue. SR515 Rx will run either servo, but never both at the same time.

[Relimar]

Using a Spektrum DX5 Pro Tx with the intention of running the 2nd steering servo off the potentiometer knob. Setup correctly and will not output. Tried again with normal 4WS setup using Mixing, will not output. Swap rear servo to front plug, rear works fine. Move front & Rear to every possible STR, AUX 1-2-3 locations on the SR515 Rx and it will do ONE servo at a time and never both. The Tx is brand new, not sure if there's some other setting I'm missing or maybe the 515 Rx is bad?

Any help is appreciated!

Dunno Relimar. I just aquired a DX6C few months ago & today was fine tuning a couple rigs on the TX settings. There's alot in them to scroll thru. Channel % & stuff I've yet to get into. Timers, etc.

Finally got it working!! Re-bound like a dozen times, checked all the trim menus etc and nothing. Noticed I seemed to be missing status/position bars for the AUX channels from Trim menus, STR and THR were the only ones showing in multiple menus. Dug out a 2nd SR515 from another truck and it was exactly the same. The only thing I could think of that I did differently, was because it was the more awesome DX5 Pro, I set the Frame Rate to the fastest 5.5 millisecond response time. The DX5 Pro Radio and the SR515 Receiver are listed as compatible with a 5.5ms frame rate. Re-bound one last time at a reduced 11ms and all the telemetry turned on, the aux channels appeared and the 4WS started working!

Cool, glad you got it. I've been reading on some of what you described. I'm gonna try a GPS sensor that is a MPH telemetry reader & plugs into the X-bus port on a SR6110AT. The frame rate has to be a certain setting & some other stuff has to be checked in the settings. Also using AVS & similar items to set. This RX has to have CH1 & 2 open for AVS to work.

Nice. Yea I feel like a casual surface vehicle is barely touching the capabilities of some of these systems. I don't race, so the telemetry is just a novelty. I got the pro controller because it was $100 off and has the knob on the side to have proper 4ws control instead of this switch on/off mixing system they have.

What's nice is the GPS reads all kinds of things & doesn't need charging like a stand alone unit. Runs off of the RX. No more waiting on the SkyRC GNSS to charge. The TX will go to the GPS telemetry screen & stay while running & can watch it real time. It's full time read, not drive by.
