Nice one James. My goodness that's a long way up!

That's huge !!! Had no idea it was that high up !

And the rest of the story.

The stirling started life as the S.31 (better known as the M4), a half scale plywood model powered by four 90hp engines (very cute by aircraft standards), her chief designer did want a 112ft wingspan but the air ministry were having none of it, insisting on the 100ft still, which reduced range but also made the stirling maneuverable enough to earn it the nickname "The Fighting Bomber", it also hugely increased the lake off and landing runs.

It was found with using the S.31 that an extra 3 degrees of wing incidence would hugely help the problem, and so the landing gear was lengthened to 23 feet to give the extra 3 degrees, hence all stirlings had the long legs.

This wasn't the only problem, the landing gear was too long to retract into the nacelles! So a two stage system was introduced, first the gear was taken vertically upwards, then backwards, the motors for this process being inside the fuselage in case of a motor failure.

This wasn't to be the stirling's last undercarriage problem though, the gear on the first full size prototype's first flight collapsed on landing! This was to do with the alloy used for the legs which was later replaced by steel, and the undercarriage problems were finally solved! so there you go, long legs= higher incidence.

Thanks for sharing Mongoose . Very interesting aircraft site, Regards, Scott

I had

so much fun modeling the landing gear on that one.
