What you say is interesting, Simon. What benefits do I really want? The reference in RCM&E wasn’t very specific about the benefits. Rather, it talked about ‘transforming’ the ‘effectiveness’ of a vintage section wing. I guess that an improved speed range would be useful, but perhaps thinning the section, as you suggest, might achieve that. Food for thought. I will try and contact Simon Cocker to explore what he sees as the potential benefits.

Thank you, Frank. I’ll follow your scalesoaring suggestion, and will also look at Dev Wing.

I want to follow up a subject Simon Cocker introduced in the June 2019 edition of RCM&E - namely building vintage wooden scale sailplanes with modern high-efficiency aerofoils. I have an (unbuilt) short-kit for the 1937 German "Rheinland" (the 1/5th scale version by Mick Moore) which I'd like to update with a modern aerofoil. This is new territory for me. Can anyone offer some advice, including choice of aerofoil(s), best software for printing them out, suggestions about computerised production etc?

Hi All, I’m building the Bambina from the plans and article in the 2019 Special Issue. Interested to see the (short) 2017 build thread, which has answered a couple of my questions. However, I would appreciate guidance on the following: The article says formers are liteply; the plan says they are 3mm ply and the drawing shows 2mm formers except F2 (looks like 3mm balsa but can’t be, surely) and F3 which is 3mm ply. Shall I use 3mm liteply for all of them? The plan says ‘canopy from pop bottle’. Not sure I’ve seen any pop bottles with that shape. Has anyone experience of pop bottle canopies? Am I perhaps better off trying to mould one as shown in the Special Issue article, perhaps using a pop bottle as a starting point? Peter
