Helicopter repair parts

I need parts for a helicopter that was given to me by a friend. I am unsure of the name of it or the model, but I do know it's stands about 4' ft. Long, has metal and aluminum framing, it has a engine made by Kioritz corp model number
SRM-200DA and the radio controls system is a FUTABA FM 7 channel receiver model # FP-R107G. I hope you can help me in any way to try and get my helicopter back in operation?
