Im glad I have a basement plus an extraroom to work on my rc's and chinese pocketbikes...I use the garage for the dirtbikes/quads and my ProStreet 69 Olds

If youre gonna keep nitro powered vehicles in temps below 50 make sure to set the engines with the piston at bottom dead center position so the cylinder doesnt shrink tight around the piston stressing it.For the gassers be sure to use a fuel stabilizer and lube all key points to the chassis...another thing to consider over thetemp rangeis the amount of humidity that accumulates in there.Cold/warm fluxuations in tempscan condense metals pretty easily and oxidize up aluminum aswell as start rust-ups.I left my brand new chinese pocketbikes in the garage and sheds over the winter a few years back..When I pulled them out in the spring I became disgusted with what I saw.My basement is always at 55-60 degreesyear roundand relative ambient humidity is at a controlled 60-65%
