Evan, That is an intriguing concept. It would be interesting to see how the many possibilities play out over time.
I have one basic question for anyone more familiar with aerodynamic theory than me. I.E. everyone. Obviously, all things being equal the lighter plane will fly longer, but does Evan's wing loading formula neutralize the weight advantage & create a level playing field? I.E. Does this become truly an accurate measure of overall "system" efficiency?

Subject: [Indoor_Construction] Idea for a New Event
Seems there's a lot of talk about new events to bring in participants. No matter what wing dimensions, weight restrictions, or other factors you use, the goal is the same. How about an event which involves flying the most efficient model, but not necessarily for the best time. Here is what I came up with:
Dimension Rules:
-Max Wing area of 50 sq inches
Scoring
-Wing loading will need to be calculated. To calculate wing loading, weigh the entire airplane (rubber included) after each official flight and divide the mass in grams by 50 sq inches.
-To find the score, multiply the wing loading by the time in seconds
Example:
5 gram airplane, 2.13 gram motor, flew for 6 minutes.
7.13g / 50 sq in = .1426
.1426 x (9 x 60) = 51.3
Score: 51.3
What do you guys think? It would definitely be something fresh and new in my o pinion.
