Prop de-icing should be the next feature :)

A few plus Celsius and foggy and they looked like this after landing.

Fog will do it! Few + on the ground easily few - in the air.

Did it affect performance at all??

I did have a crash this winter because of a completely iced propeller blade, although it looked way worse than that one... Completely destabilized the drone, I guess because of the extra weight... The "perks" of living in north Canada...

Not the weight so much as throwing off your lift.

I'm right up there with ya bud. 3 good months of flying weather!!

Not this year though, nice warm winter and even better spring.

The weight of ice is a going to effect the flight handling. But it's the spoiling of lift on the blades that's causing it to crash. Way way way before weight becomes a factor. Once that leading edge and top surface is spoiled by ice, you're done.
