Setting up steering/throttle channel mixing on your transmitter or mixing module may generate correct throttle and rotation signals for your drive motors, but that doesn't mean your robot will respond correctly to those signals:
The polarity of the motor leads may be reversed;
The left and right side motor controllers may be plugged into the wrong receiver ports; or
You may have turned on a mixing option on the motor controller board that competes with transmitter mixing.
Answer three questions about your robot and our interactive 'Mixer Fixer' will give you a complete and accurate solution to your mixing problems.
Help and Usage Notes
Mix Type - If you are using using a transmitter mix, the troubleshooter assumes an 'Elevon' or 'Delta Wing' mix using Elevator 'CH2' for forward/reverse and Aileron 'CH1' for left/right. If your mix uses other channels, subtitute them for the channels referenced in the solution.
Invert Switch - Some DESCs and mixing modules have an 'Invert' cable that plugs into a switched transmitter channel to reverse throttle response when driving inverted. If you have correct throttle and steering response but your 'Invert' switch just messes up your steering, this two-step fix should get it working:
Swap the places of the two drive control plugs on your receiver - unplug them and plug them back into each other's ports; and...
Physically reverse the polarity of the power leads from the ESC to the right-side motor.
Pistol Grip - 'Pistol Grip' style transmitters as commonly used for R/C cars have a few quirks that can cause difficulty when using them with mixing DESCs or mixing modules. A full walk-thru setting up a 'FlySky FS-GT3B' pistol-grip radio and a 'Scorpion Mini' DESC is available here:
