Yes, the Dynon AP does have min and max airspeed limits that you set in the setup menu. It also has a VS rate that you set in the setup menu which governs the climb or descent rate that the AP holds when changing altitudes (limited by the min and max airspeeds). There are a lot of ways you can use these settings, but it is not very convenient to enter and adjust the setup menu each time you want to use a different climb or descent rate. I can't wait for the AP76.
