Simple project, willing to pay $$$ for basic coding - 4 Servos + Ping)))

PaulS:

        servoSpeed[roll]= inches/10;

servoSpeed[pitch]= 2 * inches/10;
        servoSpeed[yaw]= 2 * inches/10;
        servoSpeed[Boo]=  inches/10;

If they are all to be the same speed then the code needs to be ...

        servoSpeed[roll]= inches/10;
        servoSpeed[pitch]=  inches/10; 
        servoSpeed[yaw]=  inches/10;
        servoSpeed[Boo]=  inches/10;

although it might be quicker to calculate it once and use it several times

        int Speed = inches/10;
        servoSpeed[roll]= Speed;
        servoSpeed[pitch]= Speed; 
        servoSpeed[yaw]= Speed;
        servoSpeed[Boo]=  Speed;
