I thought some might be interested in the attached flight video by my friend Chuck which was the second flight of my 1/12 scale Curtiss HS2L.
You will see that it flies very well off land. Later flights from water were very pleasing as well.
Watch the video to the end and you will notice a change in the motor sound when two things happened. 1- a battery cel voltage sagged. 2- the motor mounting table shifted. Both of these occurrences caused a significant loss of thrust, resulting in a tip-stall as I tried to turn away from the forest.
Lesson learned: Glue the struts supporting the motor table, ensure all batteries are fully charged and balanced, always keep some throttle on, even on landing.
Happily there was little damage, and since then, the plane has flown very well from water too.
Yours, Jon Harper
