Thanks kmeyers, I did remember that I did not use a throttle curve, which I am going to add. I do not slam the throttle as a general rule to avoid torque rolls, or similar. Especially on a maiden, which this was, I advance the throttle slowly. However, on this, all I did was advance the throttle 1 click resulting a change from full idle to full speed. I have other servos that I can substitute if needed.
