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.
