I'm going to sound like a fool but there's no way around it.

I bought my boyfriend a EXI 450 squadron kit.. it came in the mail today, and for some reason I though it would come with a charger and remote control like those I have seen before. I don't even have the most basic understanding of radio-controlled helipcopters.. I have no idea what I need. Obviously I need a radio controller. Do I need an engine?

What do I have to buy in order to get this thing flying? His birthday's coming up!
