About 12 of us unloaded and assembled the raven human powered plane
at the Museum of Flight yesterday morning. It will get disassembled
this evening. If you want to see an all composite 115 foot span
glider with underpowered variable pitch prop this may be your last
chance.

A nice article with a couple of pictures in today's Seattle times.
I had a lot of fun doing the fly by wire electronics for this project.
The horiz stab and vertical fin are both full flying and each is
motivated by a Futaba S9402 servo just forward of the pivot points.

Power is supplied from a set of CP1700SCR Gordy cells and the run
from the battery to the servos is 32 feet. #18 wire is used for power
with a 30,000 Mfd capacitor at the tail to supply the servo starting
loads. The servo signals are delivered to the tail via rg196u.
