no the auto level should work at all times. are you saying it doesn't stay level? this is not the Auto pilot Key. this is the "LEVEL STABALIZER" and I think it is located for mapping near the top of the list.
other than that, What I have read is that the smoother you fly the plane as you get set up, the quicker the scope site becomes visible because the Gyro needs less time to chill out. which is the difficulty I am trying to overcome. if look through the bomb site while you are on the runway, the site will be up. I have been playing around with how much I can move the plane for correction before the site goes out. I was able to fly the bird through the site and still maintain the Gyro for small movements.
