I flew Chuck Markos' Science Olympiad (still trial event) Capacitor
plane yesterday for 5 two-minute flights. It uses a 10-Farad capacitor
charged with 2 AA cells and uses a 6- or 7-mm diameter pager motor and a
65-mm diameter prop. The article and plans appeared in the 2011 NFFS
Symposium Report.

I have mentored Science Olympiad model airplane events at the local
middle school that my two kids attended long ago. I think that Chuck's
Double Whammy was also intended for Science Olympiad. I have seen the
plan and article, but never built one. I believe that these two Markos
designs were aimed at the same objectives, have about the same flight
duration, and have about the same complexity. The power source is the
only major difference.
