All good things come in 3’s

3 flights this morning – all identical – and good.  Vertical take-off, and no drift.  Sadly then a cold breeze took the sensors outside of the calibration range, and she shuts down mid-air.  No damage though.

I hope I can resolve the temperature calibration by adding a bit of d gain to the thermostat PID, but if that fails, then the only option is to encase her which is hard as there’s not much space between the top and bottom plates where she now lives.

Fingers crossed for the D-gain.
