One of the notable features on the SE5a is the transparent inspection windows for the aileron and elevator linkage. Here is a photo of the full size taken from a French site where they have restored an SE5a. Click HERE if you want to see all the restoration photos

These need to incorporated for scale authenticity so I want to make them “working” if at all practical.

The first problem is the pulleys; at the scale I’m building they need to be 9mm diameter, I’ve been unable to find any available commercially so turned some from circuit board. I’ll not include a photo; after all, if you’ve seen one pulley you’ve seen them all but if you’re interested you can use this link to a thread about them http://www.scale-models.co.uk/t2363-help.html

Next there are the control horns. These a quite thin and as such would be too weak cut from paxolin sheet, metal seems to be the only viable material. My first attempt uses wire as the “outline” in filled with balsa; this means that the holes don’t have sharp edges that would of course quite quickly cut into the control cables

The photo doesn’t give the correct impression of the shape of the horn, because of perspective it appears to be a lot less tapered than it really is. Although this method seems OK I’m not really happy with it, I’m going to try cutting the horn from sheet steel then use a yoke to attach the cable but just how to make a yoke at this scale I don’t know.

At least I’m now confident that I will be able to use the scale linkage so can start the modifications to the plan.
