RE: a question for all revo owners
yes u can run it in the winter with a little bit of preventitive maintenance. In response to wrapping th ecooling head..YES. U can use neoprene or a 0-3 baby sock I found works the best.
You will also want to heat your motor up if it is stored outside with a hair dryer or something of that fashion so you don't do any internal damage.
I would buy a body and not drill it out to vent or tape up your existing hole since you will need to keep as much heat as possible.
As for all your electronics.....batteries.....I buy balloons ni small and med size and wrap all my components to keep the moisture out.
After that u are ready to go....hope this helped!
