Help me identify this flight controller

Can anyone help me identify this flight controller? This quad came from Timerider's collection and I sold it and a few more small quads to a buddy who flys Helis. He brought it back because he could not get it to work. He thought he was not able to get the rx to bind but I was able to bind the rx (at least I think so) but nothing else would happen (other than a light comes on the flight controller). The strange thing was, after binding the rx light would stay on and quit flashing like it is supposed to, then after cycling power on it and taking out the bind plug, the light would start flashing again sometimes and a red light would stay on in the rx. Sometimes the light on the flight controller would stay on and sometimes it would be off. I spent about 2 hours messing with it and gave up. I would like to figure out what flight controller this is to find the instruction manual for it and try to get it working. I told my buddy he may be better off buying a new more modern flight controller and installing it but figured I'd ask the Bros first as someone may recognize it and give me some things to try to make it work. Thanks all!
