Re: Vex motors pulsing under RC
I think you accidentally posted in the wrong sub-forum. This one is for FTC (FIRST Tech Challenge) which uses LEGO NXT + Tetrix, not Vex.
Just above this one, under the competition forums, there is one just for Vex related competitions: http://www.robotc.net/forums/viewforum.php?f=53
If you post there, I think you'll get a better answer.
