Puff epidemic

For the 3rd time in 5 months, got a puffer. It was a mild puff on an $85 4.1Ah. VicaCopter is officially more expensive than a full size R-22. After it cooled down, the puff went away.

China is increasing the trash load to compensate for dollar inflation, probably marking 1C batteries as 20C. The best solution is to use smaller batteries in parallel & throw them away as they self destruct. Mercifully, xcitebattery is now completely out of stock.

Unfortunately there was no wind in the wind tunnel, but we did get the stiffest heading holds so far. Software triumphs over physics. Besides heading improvement the camera power seems to miscalibrate the gyros & we get serious position oscillations until they correct in flight. The heading routine doesn't recalibrate in flight, unfortunately.

Calif* is back to an offshore flow, & that means more smoke.

VicaCopter was on the scene of the smoke, complete with the latest yaw damping. Today we have timelapse from the onboard camera, ground footage showing the yaw movements, & a dead battery.
