Ok fix the traxxas wing mount really its below freezing give it a beak mang I broke one in freezing temps but the one I have now is great. Look up my build early on i have a vid of how I broke it so ya the traxxas wing mount is great above freezing. Traxxas wheelie bar is perfect for the revo enough said. Also if you are sub 45 degrees wrap the cooling head in aluminium foil be it the duct tape or renolds wrap more heat in sub 45 degrees the better but not from running it too lean. A sock cut down helps with heat retention and some plastic blocking off snow from contacting the cooling head helps tremendously not to forger run a hot plug. Really you should have a set tune to run all year with minor tweaks but winter running you HAVE TO INSULATE the cooling head. I also recommend the outerwares pre-filterer as it keeps water off the filter and blocks large particles of dirt.
If you look at my build i did a lot that kept water off of all the electronics. To the point where I blasted the entire truck with my shower head direct and no water passed any of my seals. Me and Al have a lot of time winter running only reason he has more time than me is because at -20 my fuel gelled up and I don't like to be out side in that temp.
