KML from 2nd run 2011-12-03%2004-47-05.decending2.kml
OK, here's my first attempt. Times for three laps:
1:38
1:38
1:39
Slow, but consistent. You'll also see that I overdid the size a bit, at 237 m. Even though it didn't always go around the WPs, I think I'm OK on distance.
I'm using a Parkzone Radian with standard power system, APM2560, Ublox GPS, no airspeed sensor, and Xbee downlink. Flying at 80% throttle setting. It doesn't really want to go faster with any more. I got about 10 s out of the lap time by tuning the PIDs, but you can see there's more to be had. Things were even more S-shaped to begin with.

I've already made a posting in the contest thread.

to remove the s shape, disable crosstrack.
