Brad Lowe,If the vid of the plane flying is not the one they built, it is very misleading indeed.Looking more carefully Ithink I can see three different aircraft.Do you know of them first hand?
Regarding the power plant, they show a picture near the bottom of the drop down series, that shows the power plant mounted (not the plane?) and someone holding one.
I had assumed that the power source was batteries in every case.
