Ventus rigging advice, please?

anything once the first wing is in.

I struggle to get the second wing to fit, never knowing whether it's a bi

high or a bit too low. The ground is uneven and sloping, which doesn'
help.

I hope some Ventus owners can give me some tips, please?


Fit the left hand wing first (front stub spar) and support with wing stand.
Make sure that the wing is fully flush with the fus (requires water ballast
shut, flaps neutral and airbrakes unlocked). Insert the main pin into the
spar by about 1 inch and put wing tape on the top of the fus/wing joint (to
stop the wing getting pushed out when fitting the second wing). Adjust the
wing support or twist the fus in the belly dolly to make sure the wing stub
is located vertically central within the right hand side of the fus. This
is the important bit for simple rigging.
Now fit the right hand wing which should just push straight in with just a
small vertical adjustment. I NEVER need to look in the fus to get the right
hand wing height correct, the lead on the wing pins does that as long as
you are in the ballpark.

Rigging the Ventus is just like a Discus and around the easiest of the
modern.

Hope this helps.

And yet no one is asking how to rig a AS or LS.

Maybe the problem is just me!

Nope, it's Schempp.

Nothing wrong with SH, it just takes skill rather than brute force to rig one. I prefer a SH to a brand S any day.

Yes it takes skill or bag of tricks which is not needed with 2 pin wing.

I remain to be convinced about that as a generalisation. My ex-JS1c and current ASH 26e with 2 non-tapered pins need to be incredibly accurately aligned to get the pins in and can sometimes can be very frustrating. OTOH a previous LS7 with 2 x well tapered pins was very easy. I have had 5 single pin SH gliders (and a 6th soon) and all were fine to rig albeit a bit tight for the first few riggings if new.

Not even that. Its single pin vs two pin spar designs. I've flown and
rigged both, single pin (Discus, Libelle, SZD Junior) and two-pin
(Pegase, ASW-20).

For my money a two-pin system is easier to rig because, once both wings
are fully home on the drag pins its just a matter of moving a tip up or
down until the first wing pin slips in. Then the second pin usually just
slides in without fuss.

By contrast, with a single pin system you have six or seven pins to line
up exactly (drag pins on both wings plus the two or three spigots on the
spar ends) before both wings will fit far enough in for you to even think
of putting the main pin in. This often involves considerable faffing
about and strange mutterings. Then the main pin goes in without any
trouble. FWIW Libelles and Kestrels can be easier to rig than SH gliders
because all pins and sockets are out in the open.

Agreed, Martin. Possibly the same with a JS3, since due to space constraints it uses the one pin and more-to-align technique. At least with the JS3 a side-hinged canopy isn't in the way.

Tim, please explain the brute force bit.
Is it the brutal hydraulic trailer ramp jack used to align the second spar pin? I really miss that simple assembly technique on the Duo.
