I have two questions-
Fhhubar
1) You say that with the crow or butterfly it is going to some down fast. I thought the idea of the crow was to slow forward motion and give you the ability to slow down the airplane (and control elevation)? I was thinking corw would help slow down hot landings, or is this what just flaps is for?

2) Paul, How did you get the surfaces to move so slow in your butterfly example? Is this a setting on your radio?
