Update to the build.
I now have all 4 wing halves built, and I have modified some of the parts.
The plans/article calls for the curves on the wingtip and the tailplane to be built using laminated 1/64 ply. Whilst I have no doubt that this is stronger than the way I have built mine. I don’t like it as it reminds me of the hours I spent a couple of years ago sanding down wing spars for an annular monoplane.
I decided to reinforce the 1/16 fin/rudder/stabilizer, by sticking 1/16 doublers top and bottom to the edges of the parts. This then allows the final shape to be easily sanded down to shape, and the extra bits which look untidy when finished will be hidden by the covering.
The wing tips I did similarly by adding a 1/16 wing tip down the centre line of the Rib, and reinforcing the edges with 1/16 top and bottom. In this case I believe this will be stronger than a single laminated tip “tube” as shown on the plans.
Another diversion from the plan was that I added the centre spar to the top wing. The plans do not show this, but after feeling the flexibility of the lower wings which I built first, and having already cut the slots in the ribs, I believe this is a bit of weight well spent.
One comment in the article of the build states there are no riblets, and the plan shows them between each wing spar and indeed on the tailplane. I have fitted them as they do seem necessary and will be visible under the covering.
The aileron hinge section of the wing calls for the trailing edge to be closed with scrap balsa, where it is not reinforced for the hinges. In this case I have closed them with scrap 1/16 with 2 small bits of 16 acting as pillars to prevent them “falling” in whilst the glue sets.
The engine has arrived and I decided on the OS FS110 Pumped, as this is going to fit better inside the cowl. A surprise here is that the manual suggests up to a 16x8 prop, which is bigger than the manual suggests for an OS FS 120 Pumped which I have in a Spitfire. All the props which are advised are of a large pitch.
I would love to hear from anybody who has this engine and the props which are used.
