Box of S107 g Model Remote control Helicopter bits (Cob Lane B30)

I have two fully working GYROS infra red transmitters and a box of two S107g helicopters stripped down in an attempt to get one working. The best i managed was a short flight and it wasn't as simple as the battery. Reluctant to through his into electronic recycling as someone may have an s107 they need spares for or is just curios how these things are put together. Will give priority to a flyer and bits are available from Bournville area.
