if it has to be broken in the best way to preserve it after you fly is to run the fuel out of it and then remove the plug and put air tool oil inside and some in carb and turn the engine over a few times to lube and protect it and cap the carb. If I was storeing for an extended time I would have it off the model and vacuum sealed in a food bag, but the only time I have extended storage is when the model does not exist anymore.
