I just returned from the LAK factory in Lithuania where I discovered to my great surprise my former Ventus C (22 Tango) fully restored and ready to fly. The new owner, Martynas Bykovas would like to find a pair of 17.6 meter tips to enhance his soaring in the mild lift conditions prevalent in Lithuania. Does anyone have such available?


Never heard of any available, but....

I purchased a Ventus B #61 with 17.6 tips back in 2001 and flew it for 15 great years. My previous glider was a Ventus B with the 16.6 tips. The 17.6 tips made the Ventus incredibly mellow to fly, and allowed a stall speed of 34 kts. In light air I could usually look down on everyone else. And, in stronger air it ran very well, dry or wet. In thermals (weak or strong) it climbed exceptionally well. It was the most fun glider I ever flew.

The previous owner was planning to put on 16.6 tips, happened upon Klaus at a contest, who suggested the 17.6 tips, so he bought and installed them.

As I retired from the sport 2 years ago, I sold the glider to a guy in Oregon. Still have lots of fine memories of that 17.6 meter bird! And photos of, and photos from. It was so stable in flight, it made an excellent aerial photography platform.

I'm sure the 17.6 tips help the Ventus B a lot, but high speed could present a problem.................remember the guy that added unauthorized tip extensions that worked great until he started a high speed final glide. As some point, the wing twisting (leading edge down) started increasing the speed until full back elevator wasn't enough to stop it!............ Pilot is no longer with us!
If I was flying a 17.6 Ventus B, I'd back off 20 knots (or more) on the VNE and Rough air redline.
Hope this helps,
JJ

The 17.6 m addition on Ventus B #61 was NOT UNauthorized, but was authorized by the designer. He obviously knew what he was talking about. Neither I nor the owner before me ever had any problems at high speeds in 2450 hours of airtime, mostly in the strong thermal west. We're still here. But there's certainly nothing wrong with being careful and flying slower in any glider. I did my share of that, too.

I hear you, we got a reluctant OK to add 2 meters to the ASH-25 a few years back. Worked fine till I pushed hard finishing at Ephrata. We crossed the finish line doing red-line at 50 feet. Got the good finish and pulled up and rolled left because the finish was in the middle of the field and we needed to get back ease in order to land westbound on the ramp. At 45 degrees left bank, I applied right aileron, but the ship kept rolling left! Full right stopped the left turn and things quickly returned to normal because the nose was up and airspeed was decaying rapidly. I was shook but didn't realize how bad the situation could have been until I talked to the guy who was on the finish gate. He was looking right down my left wing and said the wing was bowed up in the center section but bowed down at the tip.........looked like a sign wave! He said it was the scariest thing he had ever seen! Apparently, my left aileron input caused the wing tip to dig-in and left me doing an uncommanded hard left turn at 50 feet!
No more wing extensions for this Glider-guider!

Glad to read such warm review.

In my case is it ventus c so 17,6 tips are "legal".
I will bear in mind and avoid speeds close to VNE with longer extensions.

Since it is really hard to find spare 17.6 tips, thinking that buying tip extension molds would be great option for me. I would be grateful if someone could do these.

Also i could do molds by myself is someone could lend (with deposit, fee) tips in Europe.

Martynas

JJ, that sounds like classic aerolastic twisting of the wing - shades of B-47s!
