Please direct us as to how to set a third motor on the drive train

We needed more power to go up the ramp and added a thrid motor to port 5 but how do we set it to operate using driver control? Please help. Our next tourny is in a few days!!

What are you programing your robot in? RobotC, ModKit, etc…

RobotC. I had one person suggest repeating the command and keeping for example left motor drive port 1 and adding left motor port 5. I do this under remote control and tank control or arcade control or??
Thank you for helping!

If you are using Tank Control or Arcade Control, you only need to go into the motor configuration and add another motor as “Left” or “Right” motor.
