i got into rc this summer and i want to know if i can rc in the winter without ruining my car?

Yes but there are precautions you need to take and it depends on what kind of r/c you have.
You need to cover you receiver and battery in balloons to keep water out. I also run a little bit of silicone glue around the openings (where the cases meet and the screws) of the servos to make sure no water gets in.
If you are running an electric you will need to figure a way of waterproofing your esc without actually covering it up like you can with the receiver. The esc need a way of getting air to it to cool it down. Some people make a box with openings to allow air to get to it, but not water. (or at least thats the idea...LOL)

After every run outside you should bring it in, dry it off as best you can and spray WD-40 on all of the metal parts including the bearings to prevent corrosion.

The biggest problem i have had with running esc's in the winter (snow) is that i had an esc get wet and burn up on me, and i've had an unprotected servo burn out from water also.

Yes cover them up. Balloons or bags, i drove my ever in the snow here in vegas, yes it snowed here on ground level. And i covered it up to death and it works fine no problems yet. Well there is some rusty screws.

if you are running nitro, you may need a new piston and sleeve after winter running because the cold makes the entire engine colder and tighter, espesially the piston and sleeve. this leads to increased wear and loss of some compression when you try to run again in warm weather. the best solution is to run in the winter and get a new piston/sleeve for the next summer and keep the old one for winter running. i unfortunately had this happen to me and i couldnt figure it out until i read an article that explained it. good luck. what kind of tempurature do you have this time of year in canada?

this is a long time ago.. but... when i owned a "fox".. remember those... i bought a pair of skis for the front and made my own spiked tires for the rear... was a blast to drive.... or just get a smowmobile.. rc that is..

Well i live in big snow country and probably have a longer winter season than anyone else around here (usuall first snows start mid october and last through the following april). I've been running nitro and electirc trucks in the snow for the past 7 years and never had a problem. The only precautions i've ever taken is to either start my nitro inside or heat it up to running temperture before starting it. If you don't do this the engine will wear and re-fit itself for cold running. It'll run great in the cold but run like crap once its summer again.

As for water damage and crap like that, i just don't even worry about it. I run my stuff when its COLD, so melting snow isn't a problem. Just make sure you've got sub-zero temps [:-] and use some compressed air to blow away the snow before going back inside. LoL just typing all this stuff about winter is making me shiver....

when i take mine out in the summer i got a nitro rustkler in the summer and an electric rustler in the winter i wrap the insides w-water ballons and bags so they dont get wet... u should use an electric in winter...

Nitro good point on winter driving , if you run your truck in the cold you would be best to run a new sleeve and piston on the hot days, it doesnt matter if you live in the North Pole, for best results the motor should be at room temp. before attempting to start in the first place, under 60deg , the motor is put under more stress than lets say 80deg. The P/S wear quicker under cooler temps because the metal contracts then when summer rolls around the P/S is worn so much that the compression drops because the metal has expanded, Dont get me wrong you more than likely have enough compression to run the truck but for maxium power a new P/S would do the trick , RED
