Cold weather part damage?

What I am concerned about is breaking or cracking of gear boxes and piston heads, at what point should I just stay at home this winter?

LiPO batteries should not be discharged when the battery temperature is less that about -10°C/14°F. That seems to be the operating spec I see in several places although some go as low as -20°C/-4F°.
The gearbox will be sluggish to some extent as the grease thickens as it gets colder but the motor should have more than enough torque to spin it and it will warm up a bit as it's used. The motor will draw more amps turning the sluggish gearbox further reducing shooting time. Measured voltage drops as amperage draw increases too. I tried one of those lil' voltage alarms in one of my AEGs and it started beeping very soon during shooting as the motor pulled the voltage down temporarily even in temperate conditions..
I don't predict mechanical failures in temperatures below freezing. The RC airplane community likes warm, insulated batteries when they fly in these conditions. Not sure how to insulate a AEG battery but keeping a spare at body temperature is pretty easy.
NiMH battery may be a better idea in these conditions but I've not seen the data.
