Battle of the blades

Put carbon blades back on & began testing the 2Hz barometer mode. Carbon blades have less coning, less wind influence, less drag, & cost 3x more than plastic. The reduced drag shows up in the yaw trim.

Ran out the transmitter battery in a 1 hour test flight marathon. Basically lived in the air.

We now have a 0.0001 gyro bias weighting. Had 2 anomalies where she entered catastrophic position oscillations in a strong vibration mode of the blades. Reminiscent of a stuck cyclic. Nothing unusual in any flight recording & couldn't reproduce it anymore.

Noticed how noisy she is from the sides despite being very quiet from the front.
