Start with room temp lipos, not cold.
Make sure all snow/water gets removed and dried before storage. Air compressor works well. If not, give it a few shakes upside down. Open receiver box to dry also.
A quick spray of wd40 around the metal or bearings will help prevent rust. I like the og stuff but the silicone version is what gets reccomended by most.
Plastic gets more brittle in the cold.
