What do you mean by exposed spar stubs? How are they more exposed, and
to what, in the 19 rather than say the 24, 27, 28, and 29.

I'm familiar with Discus 1, 19, 20 and Pegase innards but not with the
others, so I was restricting my comments to gliders I understand. I
didn't mention the 20 since its very likely that the mixer is exactly
where you'd want to put the BRS.

By 'exposed spar stubs' I meant that there's no obvious tunnel, or top
and bottom guide channels, that the BRS webs could could go round the
outside of so they are guaranteed to be round the spars after the glider
is rigged: you'd need something like that to keep the webbing loop open
and let the spar stubs fit easily through them.

The 19/20/Pegase fuselage also has a battery mount in front of the spars
that would need to be cut partly away to allow the BRS webs to come round
the front of the spar. I don't think its structural apart from supporting
the batteries, but even so making clearance for the webs may weaken it
unacceptably: you really don't want the batteries ending up sitting on
the wheel well after a 'firm' landing.
