Being an opportunity knocks buyer..
Picked up a 2nd HS1550 this is a sloppy fit - put in a request to Armstrong - for their approach what is yours?
My current set of 3 wings fit tight to hex fuselage.
Fix needs to pad inside of 1550 hex female surfaces.
I experimented with narrow 50mm lengths of wet and dry (1200 grit) so basically paper thickness.
2 of these on 2 faces of the hex with one of the hex surfaces = a gap between were optimal. = Not much required but measured at the tip the wing moves 20mm up and down... (To visualize - assume 1 to 6 as hex surface labels strip W&D on face 1 and 3 or 2 & 4 or 3 & 5 ...)
Current thoughts...
1). paint epoxy on two 1550 faces and then refine fit with a file?
2). Cover male fuselage with film (gladwrap) and use rolled out strips of epoxy paste and shove wing into position and let it set?
3). XYZ product = Easy to use tough paint / glue which can be applied using a small paint brush.
There was a post about doing equivalent to this sometime back but stuffed if I can find it
TIA

There was a whole thread on kiteforum about this, but it was mostly the owner taking shots at Armstrong. I remember there being some useful suggestions, but you'd have to wade through a lot of dross to get the goodies. I *think* your option 2 was the best solution...

seems to be the one downfall of the armstrong system and seems to be caused by frequent changing of wings when you end up with salt, sand and grit inside the connection which wears it down over time.
Some solutions I have heard work well:
- Plumbers teflon tape wrapped onto the end of the fuse
- aluminium foil used as a packer inside the wing
I would avoid trying to add epoxy to it. epoxy does not feather well in my experience and can get real messy real fast and then you may need to sand off excess and you may remove more material than you desire leaving you in a worse position than when you started.
Have fixed this once before. Was painfull. About 2-3 hours.Epoxy and cabosil mix brushed on to the fuse. Sanded it till it went back together. Used sandpaper glued to a hard block. Kind of like a file.
