I was kind of surprised when I put the weight, wing area, and wing loading into a spreadsheet. Here is what I found

Dave Patrick 330L 78" 1220 sq in 16 lbs 30.2 oz/ sq ft
Aeroworks 33% Extra 104" 1880 sq in 26 lbs 31.9 oz/sq ft
Hangar 9 Cap232 97" 1750 sq in 26 lbs 34.2 oz/sq ft


The Dave Patrick (lowest wing loading of the three) with a Brison 3.2 had the most vertical (shot up like a bottle rocket) and the least 3D ability. The chart doesn't show it but it was too heavy. It needed more wing area like the new Extreme Flight Yak 87" 1450 sq in 15lbs. 23.8 oz/sq ft.

The Aeroworks does unbelievable 3D manuevers. The H9 Cap outshined the DP330. The DP should have had a glow engine on it and brought the weight down to 14 lbs. The Cap would do even better with my DA-100 in it (it has a Mac Minarelli 85cc)- would be 1/2 lb lighter and more horse power.

Wing loading is a factor. Power to weight is important too. Power to wing area seems to be another factor.

It would be instructive to compare thrust to wing area and thrust to weight.

The Extreme Flight Yak does fit into your formula of 24 oz/sq ft or less. My Aeroworks Extra comes in at almost 32 oz/sq ft and does just unbelievable 3D!!!
