The radio brand is Hitec Optic 6.
I have taken pictures of the receiver, that came with the heli (they foo-bared with it and sent me a 35MHz receiver and a 40MHz transmitter), so I will be using the receiver, that came with the radio system. btw are the receiver and servos supplied by a separate battery pack (this sounds somewhat fishy to me because I wasn't told anything about having to buy extra batteries)? Their voltage rating is 3.5-6.0V, but the main battery is 11.1V. If this is the case, then I will probably be able to use the stock receiver, that came with the radio system, right? According to google, the servo 'Micro Servo B205' has a 4.8V rating, so potentially it could be used with the receiver.
Ok, so the photos are here (had to make them big, so you can zoom and look at servo positions):

In case those pictures are not enough, you can look at the heli page
