Ice on blades - UK early morning flight

[Andy]

Just took the Mavic out on its first flight on a frosty UK morning (- 2 degrees) and noticed ice on the props after flight.
The Mavic held solid throughout with not a single glitch.

Cool, nice to know the Mavic stands its ground even in these conditions.

Had some on my race quad's props when flying in freezing fog a couple of years ago, not that much though. That looks like a lot, I doubt a lot more is needed to turn the bird into a rock, you got lucky.

Maybe looking at the RPM in hover flight could give a useful indication in this case, e.g. land ASAP if it exceeds 7k or so...
