Hi Dave and Peter,

The weather over the x-mas holiday has been good enough to test the D3 ESC. We only have 4 hours of flyable daylight at this time of the year but over some days I have logged 29 flights.

In general I like the D3 once in the air. The start up and landing sequence with changing throttle curves by a 3 pt switch will take some more time to get used to. I hope to get some more flights in the upcoming weekend.
