I must admit I'm tending towards 'The Markovitz Solution'*. Apart from anything else, I'm not usually a tidy enough builder to avoid a little gap somewhere when I've tried the saddle/through-wing approach.


Scale fact no. 34. When a stuck-on wing is ripped off, it takes all the fuselage markings with it.


Ghastly thought Bill, but there's a *Markovitz Solution* to that as well:  simply stick all the fuselage markings on the fin!

I like it! (Is that a literal case of ‘thinking out of the box’?)

On the Simoun, I'm now pondering the u/c. The spats are quite an important part of the look I think...

Pete, you might like the method Tom Nallen Snr used on the Skiptown Cadet. The spats are simply three laminations of 3/16 and the wheels are thin disks of ply (I think I may have just used card actually) which have no hub as such but the slots are thin enough so that the wheels spin but don't wobble. The leg fairings are a little different but could be adapted?

Enjoyed looking at your Cadet again, Jon .... Andrew Darby and yourself are still two of my favourite 'tissue only coverers' in the UK  Smiley

Thanks, Jon; I really like the look of that system and I wasn't entirely convinced by my own 2D spats plan. As the Simoun's legs are vertical I might be able to dispense with the little fillet mounts and thread, and just slightly embed the wire in the innermost layer of the spat.

Yeah that's what I was thinking. The build sequence might be a bit fiddly. I made the whole spat first and then inserted the wire axle - trying to find the wheel hole was interesting! I omitted the threaded bracket and just glued the paper fairings to the spat with a little tab. Held them fine.

I was worried about thin CA running in and sticking the wheel. I didn't (I was careful) but even if it had the wheel surface in contact with a gym floor is so small that it would ROG even if they didn't spin.

Pete,
        Just a thought given that the undercarriage is on the wing maybe a short torsion bar would give some resiliance similar to the my Mchard Hurricane, but beware of the leg fairing puncturing the tissue. I cut mine away slightly.Another slightly different build>

That's a good point about the leg fairing cutting into the wing tissue, Ricky. It's happened on a few I've built, so this one will have a bit of a space as you suggest.

This then is the redesigned spat, using the system Jon suggested. Actually quite similar to the spats on my Dewoitine now I think of it. Also, here's a general progress shot now I've started adding in a bit of structure.

I've been following this thread with interest Pete having failed in my own attempts to master CAD . This is looking really good, very impressive

Looking good, Pete  Smiley .... Jon might have a point about the obscured fin, but it's never a big job to change should the need arise.
