Many many years ago (15?) I saw what was left of the "Kingfisher" in a hangar at Barwon heads VIC. The more Ron Fisher did to it, the less of it there was. He claimed it to be his own work, (but had previously advertised it for sale as the factory 2 seat prototype.) He had ex RAN test pilot Keith E test fly it once or twice, and I believe he found it somewhere between unpleasant and frightening. When I saw it, it was butchered beyond belief, the engine had all sorts of crappy cooling shrouds all over it, the tailbooms were being replaced with heavy 6x3 or 8x4 inch alum box sections, supposedly because the originals started flexing wildly in flight Ron was telling me, it had about a dozen or more 2lt milk bottles on the floor of the nose for flight ballast, it was in a real state. Ron's then mad-scientist plan was to make it into a push-pull twin, with two Jabiru 2200's, with the front engine being the extra required ballast. The more he modified it, the less of it there was. It was beyond saving by then by the look of it. Dunno what happened to it. The End.
