This plan was first published in FSM back at the turn of the century. Some years later, I updated it and built a new version, using the old plan on which to build it. This is the chronicle of the later build for anyone interested in building one...
Note: the fuselage is constructed on a jig: the pics show it after it has been removed...

The ply fuselage sheeting was reduced from the 1.5mm of the original to .8mm. In retrospect, the lightening holes were pretty much a waste of time...!

Half-round Ramin strip seems to be gone from the shelves these days: apparently Ramin has become one of the endangered species...

Lovely, thanks Chris.
From the photos it looks like the wing joiner box sits flush to the former but the plans show it angled back .

No way I can remember what I did back then, Adam...! Just set the joiner box in such a way as to achieve the correct angle.

Compared to some the older vintage gliders, the canopy on this one is relatively straightforward...

Looking back, this must have been where I gave up on tapered spars for wings and opted instead for dropping in a sub spar after construction to form an I-beam...

Note that the barn-door type spoilers are not typical of the Bergfalke...The scale DFS brakes, however, are definitely not slope-friendly!

That's about it for the Bergfalke... I'll rummage around for a video...

It's with some sadness that I view this video now: the conditions that prevailed that evening a decade ago, once so common, are now as rare as hen's teeth...

There are so many things that have changed in the world over the last decade or so. People of our age have, I think, had the best years!
Great video Chris.

Word to the wise for anyone contemplating this build. I bought the part kit from FSM some 18 months ago and opened it last week.
The formers and many of the important ply parts have been cut from 1/16th ply not 3mm. I have told them but no response received.

If I am not mistaken, they get their kits cut by Belair Kits 01953 885279. May be worth giving Leon a call and telling him. Don't hold your breath though as he is only cutting what he has been told to by FSM. If all else fails you can get a good short kit here: https://lasercutsailplanes.co.uk/produc ... -kit-plan/

Thanks but the plan itself may be the cause of that confusion as well as other issues beyond my patience to correct.
