Default How hard is a Diamant to assemble?

A friend of mine is considering buying a diamant. He was told it's
very hard to rig. He's not a member of this group so I am asking for
him.

Anyone ever tried to assemble one? Or dis-assemble one?


Others have pretty well answered this already...but since I went to
the
trouble of generating this, and my news server was balking earlier,
here's one last attempt to send it!
- - - - - -

I've helped rig all 3 models (though not since the 1980's), including
an
extended-span former-18-meter version.

Rigging varies by the model/span. Disassembly of any model is (or
should
be!) a non-issue.

The 15-meter HBV model uses Libelle (301, I seem to recall)
wings, and rigs like a Libelle, except the Diamant's enclosed fuselage
aft of the canopy, covers what is open and top-accessible beneath
Libelles' removable canopy, and in that sense HBV rigging is less easy
than Libelle rigging. IOW, HBV rigging is just like almost all the
rest
of the 15-meter-span fiberglass fleet out there.

The 16.5 and 18-meter Diamants have (considerably) heavier, single-
piece
wings, which get no lighter if their span has been increased (a not-
rare
modification). Other than the weight at the tip, they never seemed
abbie-normally difficult to rig from this tip-holder's perspective.

As with all ships, alignment matters. If the person at the root
is impatient, unskilled, or - by far the worst! - uninterested in
gaining the (easy-to-gain) visual assessment skills required to
achieve
visual alignment, my Pythonesque advice is: Run Away!!! Run Away!!!
Two
wing stands may be a definite asset to the newer owner, in order to
allow the tip person to rest while the owner ascends the new-owner
alignment & assessment learning curve.

I've yet to encounter a difficult-to-rig ship...IF the root guy
understands alignment!!! For the record, THE worst assembly I was ever
involved in (a half-hour daymare) was a 15-meter glass ship (G-102),
rigged - and evidently aided by! - some absolute idiots. By the time
this tip holder figured this out, it was too late*...
