I purchased a US 41 with jumpstart and no directions on how it functions. Do you just hook a 4.8 battery to it thru a switch and turn it on while starting or leave it on during flight. If someone could give me the scoop on the I would greatly appreciate it. Thanks Rick

PS: If someone would be willing to fax me the instructions at 18008278353 Atten: Rick Poire would be great. Thanks in advance.
