I did notice that my Battery I keep int he back of my truck dosn't last nearly as long this time of year, It is one of them jumper boxes that mechanics use... This normally lasts allmost a month... That is chargeing everyday. This time of year it may go two weeks.... So batteries are an issue.. Charlie RCSE-List facilities provided by Model Airplane News.
