....the above was written a couple of years ago as for various reasons the DH2 was shunted to one side. Following a move from a room in the house to a shed in the garden, the comfy perch occupied by the model became occupied by fresh plaster and new paint. No chance of her hanging there again!
So this September I added a 2812 brushless motor and replaced the old Fleet RC gear with an Orange RX and some new servos and a 10 amp SC. The 7 cell Nicads were replaced by a 2-cell 1300 Lipo, all finished off with a nice shiny wooden 10 x 6 prop.
She flew again on 20 October 2012 (nearly 12 years after she was built) and performed perfectly, chuntering gently round the field and landing softly and safely. The covering, markings, paint and structure are completely unchanged from new. Perhaps I was quite a good builder in those far-off days!
