On page 36 of the March 2008 issue of XRC, there is an article on getting your rig ready for the snow. If you don't have the new waterproof stuff from traxxas, you need to wrap your electronics. There's also an article on here somewhere about nusing plasti-dip to waterprrof stuff, but I think balloons would be quicker. Trust me, my receiver got wet and now I can't run my maxx until my new comes in that I ordered. I really wish someone could give you a tune that would work in variable conditions, cuz that would mean I could tune my RC like Ron Popeil cooks his chickens on late night informercials as in "Set it and forget it," but what may work today will not work tomorrow in the same temp and humidity because the barometric pressure in Alaska changes overnight. Good luck in the snow, don't forget to wrapt the head in aluminum foil, and take some videos for us southerners who are walking around in T-Shirt, but hey at least in Louisiana it's so hot we can run RC's almost year around. But In July it gets so hot here that if you leave your RC out on the porch too long, the tires will melt off.
Oh yea, In the forum "post your T-Maxx pics here," there are some pics of Lessen's T-Maxx. I think it's near page 5 but i'm not sure. He has some really good pics showing how easy it is to wrap everything for snow. Well easy considering if you don't you will have to do a lot more work because you will not only have to unscrew stuff from the chassis, but also reset linkage, change wires and keep em straight, that kinda stuff.
I also read an article that said you can use a trojan or lifestlye latex product to wrap your stuff, but I think that ideas just for people that are real d**ks.
