if you plan on letting your toyz sit for the winter. i would do as mentioned. then buy some maverl mystery oil and put a few drops down the carb and rotate. then put a few down the cylinder and rotate and replace plug. you should be good togo for te winter. depending how damp it gets and where i am i will go as far as getting some silacet(that moisture absorbing stuff that come w/ high end electronics) and put the engine in a zip lock bag after doing mentioned tip and close it up. as far as electronics i do the same minus the oil. the chassis gets a through hosing of wd40 after cleaning
i think i only had to do this once. after that i said forget it and run them when its not raining. as far as keeping warm, with todays winter outer wear and pocket warmers(i.e. 1/18 scale bat pax make good pocket warmer

) you could all ways sit inside yer car w/ the heater running and play that way please have window crack for ventilation. get the neighborhood kids to flip the buggy over when it does happen[8D]
