I have the Spektrum DX4S and an SR310 receiver. Here's how I got it working with the Diff Brain.
RX Setup:
White plug from Diff Brain goes to Aux1.
TX Setup:
Assign your preferred switch on the controller to Aux1 3P.
Set Aux1 travels to 150%.
Set Dial (knob) or another switch to Aux1 Trim+
Set Trim Step on Aux1 to 20.
That's it! The Diff Brain should now be functional by using the Aux1, three position switch to cycle through the modes. The center position will make a servo chatter until the knob or trim switch is set to max trim in either direction.
Testing:
IMPORTANT! Disconnect the motor leads before testing the modes.
Position 1 should be Blue. All diffs unlocked.
Position 2a (Dial anti-clockwise) is Green (Wheelie Mode) Center diff locked.
Position 2b (Dial clockwise) is Yellow (Drift mode) Rear and Center diffs locked.
Position 3 is Red (Climb mode) All diffs locked.
Connect the motor leads and test it off the ground. Run through all the modes and make sure it allows you to run them at max speed.
Extra bits:
I tried a trim mix on a separate 2P switch to select between green and yellow modes with a single button press in either direction but it was not reliable after cycling power. The knob works best for me.
And if that's not enough, I made a video too.
Have fun out there!
