Ok...not a happy subject...but it is about time for me to start thinking about storage for the winter[]

My question is, what is the best way to store my engines for the winter. Presently I keep my planes in the garage, and thought perhaps it may not be a bad idea to take the engines and battery packs out of my planes and store them inside. Do I need to do anyting special to the engines to prep them for winter storage? How about my NiCad packs?

Thanks,

Joe
