I dug out my old plans for the Pondhopper and it does not give the degree of downthrust ( for a pusher). So I would think 2-3 degrees on yours should work. Mine was very forgiving with the Falcon 56 wing. There is not much frontal area to this design so wide open it is fast. Due to the front hatch being at water level I had a problem keeping the inside dry. Have fun.
