Dang, a 4 - 7v battery? All I got is the AA's that go in it.
Why can't things just ''work?''
sorry, i wasnt clear enough.
you can use a 4 "AA" battery holder with a reciever plug, or a 2s lipo with a reciever plug.
if you model is nitro, you can just plug in the reciever pack(whether its a "AA" pack or a nimh pack)
if its an electric model, you will need a battery pack or "AA" holder with a reciever plug
