| I hoped to have some bits of actual model to show by now, so here is an update.
While the model is very much still "on", I am a little bogged down in the design stage. I have arranged to check-measure G-AGOH, and also to measure a similar aircraft with no covering . This is to resolve some apparent issues with the factory drawings. Without this, I can’t actually build anything. I can't make the necessary visits for about three weeks from now, so it's frustrating.
For example, while on G-AGOH the aileron fulcrum is almost on the bottom of the wing, the works drawings show it about a third of the way up the aerofoil thickness and the arcs, and how they fit, or do not fit, within the aerofoil section, are therefore significantly different. This is surprising, as I have obtained a works drawing with written offsets, and the resulting aerofoil is smooth and looks correct. However, my own on-site measurements of the aileron taken from G-AGOH will not fit properly with the fulcrum in its correct position. Perhaps I have mis-measured. All I can do is measure again including, if necessary, measuring up the entire aerofoil section.
There also appear to be anomalies in the shape of fuselage produced by the measurements on the works drawings. Perhaps I am not visualising correctly.
I am told on good authority that some of the factory drawings do have errors, but it is a case of trial and error to find out which.
As I don’t have the plane in my back garden and a full set of drawings would cost several hundreds of pounds, all I can do is to measure the plane in much more detail and check my existing measurements. This time, I’ll take drawing board with me and draw as I measure as far as possible.
