I have ben flying my Zodiac 601HD for a couple of years now, and have recently considered clipping the last 12-16 inches off the wingtips for a little more top-end cruise speed.
I'm wondering if anyone has ever clipped the wings on the Zodiac HD, and what the results were.

Thanks,

Rick:

You should expect that your best rate of climb would decrease, take-off distance would increase, your best glide angle would get steeper, and your stall speed would go up. Considering the overall dragginess of the HD, the cruise speed increase might not be worth the loss in other aspects of performance.

Reducing the span will require building a new wingtip structure. Remembering what a pain that was for me, I know it will be quite a bit of work. Why not consider the option that Chris has given us and just retrofit the HDS wings?

My opinion, speaking as a retired aeronautical engineer who has taken way too long to finish my own HD.

Rick,
I remember someone building the wings a couple of feet shorter and the
airspeed gain was noticeable, not remarkable. All else seemed
to be in the comfort zone of the HDS. Landing speed increased, etc. As
a satisfied HDS builder, the taper wings do fly well. I've had to try
to keep up in climb with an HD and it couldn't be done. If I had
do-overs, I'd still fly HDS, but if I flew grass strips a lot, the HD
would easily be a best choice.

Hi Rick;
I considered that option at one time but coverted to the HDS wings
instead. A fairly easy conversion and much more speed.

I'm having trouble reaching you off-list. If you are still interested in
some clipped-wing numbers, contact me off-list.
