Paul,
I'm glad you enjoyed it!
We had a good run going last summer with no crashes. Towards the end of the year we put them in several times, so this spring we decided to "save" them for Brodaks. The flight in the video was our second flight of the year.
If we had better airplanes and more consistent engine runs we could do much better. Now if only someone would come up with a power system that would run the same every time..........

Thanks for posting, Mike
