Precedent models "Stampe" 1/4 scale biplane

3rd flight of our Stampe to test different props.
Sept. 20, 2015.
Mostly a flight to test a new engine.
Just feeling out the control responses and getting to know her.
This is our second Stampe, We had one from 1989 and by 2000 it was worn out, so we built this replacement.
