I'm just getting into the hobby and really enjoy it. My friend gave me an older Airtronics Vanguard 4 channel radio (gold stickered.) It hasn't been used in about 12 years so the batteries probably dead. The charger is also missing. I haven't been able to find out where to get a charger or batteries for that system. I know I'll probably want to eventually upgrade to a different radio, but I really need to keep my costs down and I just want to get flying. Does anyone have any suggestions. Thanks in advance.
