So I recently got my new traxxas stampede. I am new to rc and have a question about driving in the cold. Today, where I live it's -11 C but feels like -22 C with the wind chill. I recently broke a few parts the other day, after I crashed, without yet having installed an rpm bumper. I had to replace over $40 worth of cracked parts. when I wen't to the store the guy told me that I shouldn't be driving in cold weather because the plastic parts will crack, is this true?

what precaustions should I take in cold weather.
