Flying in heavy fog at -7 degrees. Also, all the sensors and the camera were covered with frost. There were reports of motor overloads.

Looks like you had a lucky escape.  Those were pretty extreme conditions

You definitely put the Air 3 through an extreme stress test.

Flying in cold, moist conditions is asking to crash your drone due to prop icing.

Rather, I was the one who was stressed.

on commercial aircraft thay spray all the flight surfaces with antifreeze in cold weather to delay freezing (they have inflatable sections to brake the ice as well as heating systems), it might be worth sacrificing a blade to see if antifreeze reacts to the plastic, if it does not react then just wipe the blades with neat antifreeze, this will not solve the problem but should give you a few more seconds to get the drone back. for the lenses, if they are glass then clean them and treat them with someting called rainx its a water repellant for car windscreens, they now make it with a de-icer in.

I'm sure there was.

Rain-X leaves a visible haze on glass and would affect the camera output. I would never put that on the camera lens, at least not directly. If you have a clear protective filter you don’t mind sacrificing, go ahead.

No coating will survive at that RPM...We have tried all, starting with WD40, oil based, spray, Pronto wax, super wax, glass treatment hydrophobic coating...
The only thing that works for a couple minutes is the spray used to hidrofobe the textiles and shoes....apply in a very thin coat 3 times on props (make sure you do not keep it on drone when apply, just take it off and put it on a large newspaper or some), leave it rest for a few minutes....will repel the water for 5-6 minutes before is gone (also from high RPM).

Cheers.

the only time Rain-X left a haze was when i first used it and didnt folow the instructions which are
Clean and dry surfaces before treatment.
Apply at temperatures above 4°C.
Spray or pour Rain-X® Rain Repellent onto a small folded dry cloth.
Apply to the outside of the windscreen using vigorous circular movements. Make sure that the treated surfaces overlap.
Allow the product to dry; a white haze may form.
Reapply Rain-X® Anti-Pluie to ensure complete and even coverage.
Remove the last film with a dry cloth or by spraying water onto the surface and wiping it off with a paper towel.
do not use on plastic/plexiglass

oh well it was a thought!
its a shame they cannot somehow transfer the heat from the motors into the blades

Edit
i think they can transfer some heat from the motors, the out side of the motor is fixed to the blade mounting system, if this was aluminium it would conduct some heat, the blabe pivots are steel which conducts heat very well, now all thats needed is a thin solid copper/aluminium wire along the leading edge of the blade that contacts the pivot pin.
yes i know its a flight of fancy and there will be other issues preventing this.

Imagine an aluminium blade on a children's face.
