Thanks Harley for the info. Very helpful thread.
I would like to share something abt rear wheel steer setup that I learnt while setting up my ax10.
I had used the same method that you wrote below and like what you mentioned, we need to keep track of the mixing, else the servo will behave abnormally.
Here's my solution.
I assign ch4 to one switch, say PS1 and setup Pmix1 similarly to what you have mentioned.
Go to PMIX1 and adjust it as follows:
LEFT: -100
RGHT: -100
MST: ST
SLV: CH4
MODE: ACT
OFST: 0
MXMD: MIX
Next, I activate 2nd Cond (in System Menu) and assign it to another switch, say PS2.
Now, when i toggle PS2, it will goes into 2nd cond.
Now, in this 2nd cond, I set up PMIX1 as follows:
Go to PMIX1 and adjust it as follows:
LEFT: 100
RGHT: 100
MST: ST
SLV: CH4
MODE: ACT
OFST: 0
MXMD: MIX
Doing the above, we eliminate the need to keep track of mixing.
Toggle between 4WS and crab walk only requires 1 switch press.
Hope that helps.
Cheers.
Rear Steer
There are number of different way to run rear steer. On this radio it mostly depends on how you run the other channels. If you are not mixing any channels already then you can mix the front and rear steering two ways to five you fully proportional steering. If you are already mixing channels, such as using dual esc's then Option 2 will be for you.
Option 1
Fully Proportional
Plug your rear servo in to the channel 4 slot for this example.
For easier understanding first go to the SYSTM menu and change DISP-SEL and set it to "SRV-VIEW". The Servo View gives a very clear bar graph style view of what every channel is doing.
Go to the *MENU-T option and change your menu type to "Level3", make sure to go down and select the EXEC function so that it applies the changes.
Now on main menu screen 1 you should see PMIX1 and PMIX2
Go to PMIX1 and adjust it as follows:
LEFT: -100
RGHT: -100
MST: ST
SLV: CH4
MODE: ACT
OFST: 0
MXMD: MIX
What you just did was setup a traditional rear steer, when you steer the front wheels left the rear wheels will steer right.
Now go to the main menu screen again and select the SWTCH menu
Change PS1: to "PROG MIX1/ ALT"
Now when you press the PS1 button (located under the wheel) you will activate or deactivate the rear steer.
Next go to PMIX2 and adjust it as follows:
LEFT: +100
RGHT: +100
MST: ST
SLV: CH4
MODE: ACT
OFST: 0
MXMD: MIX
What you just did was setup a crab walk rear steer, when you steer the front wheels left the rear wheels will steer left.
Now go to the main menu screen again and select the SWTCH menu
Change PS2: to "PROG MIX2/ ALT"
Now when you press the PS2 button (located on the pistol grip) you will activate or deactivate the crab walk rear steer.
Something to note. You need to keep track of when you have the mixing activated. If you have BOTH activated then they cancel each other out, make sense?
