The Kingfisher project is coming along very well. I started just 5 weeks ago, and it is now nearly ready for covering, except for a lot of minor details. I happen to be a very fast builder, though, and I think the average builder would take much longer to get this far! The plan is OK for the main construction, but lacking in detail for many parts, and some of the details such as wing securing pins are not so good.
I have designed and made air-operated retracting wheels, which work very well. Also, the wings have plug and socket connexions for the aileron servos and nav. lights, to eliminate the job of plugging-in wiring at the lake. Wings are secured by elastic band/keyhole slots. Trickiest job is fitting struts. I can send you some construction photos and more detailed info. if you wish - my address is:-
