Controlling Multiple Servos With RC using servo.h

Your code:

  ch1 = pulseIn(7, HIGH, 25000);
  //ch2 = pulseIn(6, HIGH, 25000);
  
  degree1 = (ch1-30); //balancing to rest at zero
  //degree2 = (ch2-30);//probably will need to change
  Serial.print("Channel 1:");
  //Serial.print("Channel 2:");

  Serial.println(degree1);
  //Serial.println(degree2);

  myservo.write(degree1);

You seem to expect that pulseIn() returns a degree value, but it's not! As slipstick wrote, it probably returns a value between 1000 and 2000. My guess is that this is not your working code. A map function is missing.
