Autonomous + flybarless + carbon blades

Carbon fiber blades went on, then a training gear test, then full autopilot. No problem with the software flybar, but nervewracking oscillations in autopilot. Also significant tail wagging remains despite gain reduction on the ARM.

Definitely more photogenic with carbon fiber blades. Software flybar did feel a bit looser on the carbon fiber, but still stiffer than the mechanical flybar. The benchmark is ground effect hovering & backwards figure 8's. Software flybar is the gold standard in both.

Well, she certainly likes oscillating. After the photo session, stepped up the I gains & oscillation except for tail wag virtually disappeared. May also be weather sensitivity. Tail wag may require gain reduction on the PIC.

Well, flight times in previous blog posts were more like 10 minutes. The 13 minutes was including initialization. Have not taken flybarless to exhaustion, but it's getting at least 10 min.

Need another rate cut & liquidity injection into the blade budget. Bernanke can use our printer until he's fired.
