I'm trying to set up the remote control so that one joystick runs 3 motors at once. Should I write the code like
motor[port1,port2,port3] = vexRT(Ch2);
or should it be like
motor[port1] = vexRT(Ch2);
motor[port2] = vexRT(Ch2);
motor[port3] = vexRT(Ch2);

Or is that not needed to increase the output of the motors?

You should use:


Also, feel free to experiment with things. Don't be afraid to try things out, and see if they work!
