My robotics team is having lots of trouble controlling the speed of our flywheel. Setting the velocity of the motor does nothing, it still speeds up to max power.
Code:

while (1){
          
    FrontL.spin(vex::directionType::fwd, Controller1.Axis3.value(), vex::velocityUnits::pct);
    BackL.spin(vex::directionType::fwd, Controller1.Axis3.value(), vex::velocityUnits::pct);
    FrontR.spin(vex::directionType::rev, Controller1.Axis2.value(), vex::velocityUnits::pct);
    BackR.spin(vex::directionType::rev, Controller1.Axis2.value(), vex::velocityUnits::pct);
       
    if(Controller1.ButtonL1.pressing())  {
        Intake.spin(directionType::fwd,1000,velocityUnits::rpm);
    }
    if(Controller1.ButtonL2.pressing())  {
        Intake.spin(directionType::fwd,-1000,velocityUnits::rpm);
            }
    else {
        Intake.stop(brakeType::brake);
    }
      
    if(Controller1.ButtonR1.pressing())  {
       
        FlywheelDown.spin(directionType::fwd,-200,velocityUnits::rpm);
        FlywheelUp.spin(directionType::fwd,200,velocityUnits::rpm);
        
   }
   else {
      FlywheelDown.stop(brakeType::coast);
      FlywheelUp.stop(brakeType::coast);
    }
 
           
 
    //vex::task::sleep(20); //Sleep the task for a short amount of time to prevent wasted resources. 
  }
}

I’m not quite sure what the problem is. What motor gear set are you using?

You are asking the flywheel run at 200rpm, what did you want it to do ?

I saw your Intake motor speed setting was 1000 /-1000 rpm, and FlyWheel 200/-200 rpm, but V5 motor top speed is only 600 rpm(with 6:1 cartridge), so if your FlyWheel motor is 18:1, then 200 rpm is top speed, no problem.

Thanks for replying! I did not realize that the max rpm was 200…
