Not goal posts Colin, the culprit was a large tree. You know the type, they have tiny magnets at the ends of the branches. The Black Magic got tangled up with the tree,it was on the edge of Avon Field, just outside Bournemouth Airport. I was quite new to r/c flying and crashing at the time. The model dropped from its original position to a lower branch, it was just out of reach. Finally a gust caused the model to be released and it fell awkwardly onto a gravel path. The fuselage broke into three pieces, but for some reason, the wings and tail were undamaged.If anyone does want the bits, be aware that the Flair plan of Fred Hempsall's original design is incorrect. I have a copy of the original plan published in 1948, that will explain everything.
I make no excuse for allowing the Black Magic to become entangled in the tree, even though I was effectively flying one handed. My right arm was strapped securely as I was recovering from some serious surgery on my shoulder. In fact I shouldn't have been flying at all. Unfortunately the enthusiasm I had then has sadly gone. Most of my flying is now in an armchair, reading either RCM+E, or the exploits of Club members on the Club website.
