with my first aftershock ( a 3.5 nitro)- one thing i noticed was that the factory plastics are already borderline acceptable. Cold makes plastics brittle, and things broke easier. Just got another aftershock, and i'll likely only run it in 50*weather or better.
however - i've been having a ton of fun in the snow with my MGT8.0 - no rust (most stuff on it is plastic or stainless - and air compressor to dry it after a run) and it tkes a beating and a half. Just waterproof your servos
I can't wait until spring to give my new 8e a try.
