Since you're referring to the "16.6 factory tips" you probably are
talking about a Ventus-B

In fact there is no choice apart from the winglets for the 15 meter
configuration.
17.6 meter tips on a Ventus B are not certified and not supported by
Schempp-Hirth.

Ventus B with 16.6m and Ventus C with either 16.6 or 17.6 are different
machines entirely. The Ventus C with the double cranked 17.6 m tips
certainly looks superb, wish I could fit them to my European B model.

When all's said and done Al. There is no substitute for span! I'm surprised
you asked this one!

As far as I know the C's had a different wing section to the B's. I seem to
remember asking Schempp about doing a mod and they were pretty blunt about
it not being possible. I also recall that the moulds for the bits were lost
in a fire or something so there are no replacement bits around.

My Ventus A came with 16.6 tips. I looked into modifying the 16.6 into 17.6
but decided it was easier to buy some tips off of another glider. My 17.6 tips
came from a Ventus CM and they fit just fine. Chip Garner borrowed them for an
18M nationals and used them on a B model. One interesting note however, The
ailerons on the 17.6 tips are longer than the 16.6 tips.

I flew my Ventus C for several years with the factory supplied 16.6m
tips, then modified them with the Schempp-Hirth mod kit to 17.6m. I
did not notice a great difference in handling, with both 16.6m and
17.6m, handling is very good, IMHO. If you believe the factory polar,
you might get a few points of L/D at lower speeds. I did notice a few
knots slower circling speed with the added span. And as someone
mentioned, they do look distinctive!!

realy are the business!

I'm wondering about the legal issue here.
The early model Ventus was definitely not designed for 17,6 M tips.
By using these tips on a early model A or B you're infringing the
limitations of the C-of-A.
In fact this will void your C-of-A.

You need to also remember, a lot of the original Nimbus 3's had the tips added
on to increase the span from 24.5M to 25.5M. Haven't heard of a single problem
from this modification. Klaus encouraged me to get a set of these tips when
they first came out but then again my Ventus is licensed in the Experimental
catagory.

Another interesting note, the tips on our Nimbus start to sweep back at the
joint and again at the bend. My Ventus tips are straight at the leading edge
then sweep back at the bend.

Hay Al, Read your Experimental Airworthiness Certificate, I believe it will say
something like this, "Any modification will invalidate this certificate."

It's not a big deal, but you got to get a new certificate after you convince
the Feds that your modification is safe and they want to see something from the
factory that says it's OK to put this mod on your machine. If you don't do it
and your insurance finds out about it after they find the "C" tips in the
wreckage of your "B", well we all know the rest of that scenario.

Interesting point there JJ.
plus the reply Ian (Tango 4) got from the factory

Guess 16.6 with a winglet might be the hot setup.
Shame Larry has a set of moulds for the 17.6 tips :-(
