Robotic sky writing 4 U

The mane reason for this was to see if the flight controller was robust enough to do it. 3 simple letters is the most a single battery charge can handle. Strong winds R forming every night, making for sloppy movement. These missions R performed completely in hover mode with the safety pilot following her all the way downrange. Increased the velocities to 2m/s to try to extend the battery range. After 20 minutes of careful rotor manipulation, she finished CAT & DOG.

Unfortunately the American electronics worked & the Japanese electronics failed. The EOS 20D died halfway through DOG. It passed 70,000 exposures & now goes into infinite mirror flips whenever powered up. Suspect a broken sensor is reporting a stuck mirror & it's trying to unstick the mirror. It was rated for 100,000 exposures & only did 70,000.

Given our 35mm lens collection, the obsolete EOS 5D may be the next move. The only major purchases for 2008 so far R the T-Rex airframe ($1000) & the HP ($1300). Everything we buy works until it either crashes or desintegrates from old age.
