Answered: Vex vs Scorpion XL

Has anyone used this motor controller with the Vex Micro?
A friend of mine is having problems with the scorpion not responding and jerking as he
tries to control the motors.
I know Victor controllers and Sabertooth works fine with Vex.
Could it just be that the Scorpion is just not compatable with Vex?

The MOTOR-CONTROLLER-100 does work with the VEX Microcontroller. It allows VEXplorers Motors to be used with the VEX System. We are not familiar with Scorpion, so you are on your own there.
