I leave mine in an enclosed trailer. I dont even bother bringing the batteries inside (A123's)
Since it is smaller and I have room for it, my jet stays in the house. However, I've stored my giant scale aerobatics planes in the trailer (down to -20F) without any problems. I also leave the batteries (A123)
in the planes. Have been doing this for the past 4 years without the slightest hint of a problem. I simply put a storage charge on the batteries and by the time Spring rolls around they haven't discharged more than a couple of percent.
