Someone was asking yesterday about the availability of a Horsa Glider in 1/48th, but I can't find the post.
Fonderies Miniture did one in 2010, Armorama Review here.
I managed to build one, Here,
My Build Photos here
This is without doubt, the worst kit I've ever managed to finish.* I got it heavily subsidised, & only finished it as a commission for club display.
looks like there were 6 different people making the major components who had a grudge against each other!
Nothing fits, gaps big enough to put fingernails through, & plastic like french cheese, in that when you sand it, it crumbles!
You must build in a spar across the fuselage & wings, or it will split, as the only other one I've seen finished at a show, broke it's back in transit.
For the Insane, there is
one available on UK ebay
For masochists: a Vacform is available from Sanger Engineering Horsa.
Also from Italeri in 1/72, & Bronco MK1 & MK11 in 1/35th.
In 1/33 card models GPM AS-51 Horsa Mk.1 Glider
* I've half-built worse kits, unfinished, btw.
