My DA does the bump thing, but it's not really bad. My solution is to have an idle-up programmed onto a switch for in flight... it keeps me from stalling in blenders, etc (I had it quit entering a blender when brand new and the idle was MUCH too low... dead stick was no problem). I flip to switch to lower the idle for landing, and since I always land smoothly
it's not a problem!!! I DO wish there was a fix, though.
