You have too much elavator throw you only need about half of what the book says for low rate and high can be what ever you want. This is from experience from the 5 caps at out field including mine. I also agree with chance12 on the incidence thing.

When I land I don't hardley even breath on the elavator to control rate of decent I use throttle mainly. I use the elavator don't get me wrong but I touch the stick and don't pull. I also use 40% expo.
