Hi Dan and group,
Interesting facts. Carbon Dragon length 19.12 feet. Axel length 19.19 feet. Hmmm... ??

CD wingspan 44 feet. Axel 40
CD horizontal span 10 feet Axel 7.97
CD vert fin 5.75 feet 3.67

Dan your quote "With good visibility, adequate structures, comfortable flying position and excellent handling, you could have a ball." sounds like the design criteria.

Please also add the capability to roll launch from Bear Mountain with a fairly heavy guy. :-)

Seriously.

Karl
