Re: Schleicher ASH31 4m
Final decision on the tail boom:
1 layer if 100gsm Kevlar at 45deg
4 lengths of 80gsm uni-carbon
Final layer of 50gsm glass, to lay down all the rogue Kevlar fibres

Re: Schleicher ASH31 4m
No idea, but guess that's well enough for belly landings!?
How easy/difficult was is to place the 100gr glass. All I uses so for was 50, and that I already found a bit of a pain in the corners..
Guess the fun job still has to come; sanding it all smooth? I'm curious what other treatments you'll for the fuselage covering (sanding, filling, priming).
Looks really nice so far!

Re: Schleicher ASH31 4m
Hi Daniel,
It feels pretty strong now. Now I need to remove some of the bumps and then fill and sand (as I did to the bottom).
The 100gsm glass is relatively easy to lay on a large fuselage like this. Spraying fuselage with a light coat of 3M 75, before laying, makes the resin application a lot easier, as the cloth does not move.

Re: Schleicher ASH31 4m
In order to get the desired nose fit, I bought the GM spinner and 17x10 scale blades.
These are designed to fit the shape of the fuselage (and are already coloured white, obviously ).
Whilst not cheap (£60 for spinner & colet), they very well made, with the spinner in carbon fibre.

To create the tail hinge, a carbon tube was glued into a slot in hard balsa, which was then glued to the fin, then shaped.

2 fibre glass tabs were made (with a corresponding hole) then bonded into the tail.
Then the rod can be run down the tube, through the tabs to form the hinge.
