My Tale of Two Tails....

 

This posting is about my experience with two versions of the tail/keel assemblies used by A.I.R. on our ATOS Rigid wings. The new “Full Carbon Race Keel” and the older Carbon/Aluminum adjustable keel.

In 2018, I received my brand new VQR. The latest and greatest “Race/Comp” version of the VQ. This evolution offered plenty of innovation and “change”. Both sweep and hang point moved forward plus the wonderful looking new Full Carbon Race Keel. The new keel and tail assembly had a dramatic increase in structural stiffness and substantial aerodynamic dampening that included a new tail trim system, flap compensation profile and elevated tail standoff (“T-Tail”).


My first flight impressions were good, the new configuration proved to be a wonderful solid wing in rough air. The static balance was improved (less tail heavy).  Combined with some nice new setup features, I was reasonably happy to have chosen the VQR. (Tho… I was skeptical I was really looking at any performance improvement from my VR06… mainly, a much nicer glider to fly).

“A much nicer glider to fly”…… thing is, everything that goes up, must come down?

(For those who love their full carbon race keels, you might want to stop reading this…I’m just a grumpy old man that decided not all the changes to my ATOS were good, as they say… “in my opinion”)

Almost immediately, I noticed my landings had taken a turn for the worst.  I soon found my timing and feel were gone and I was no longer arriving with any sort of “grace or style”… often I was arriving like a box of rocks 😉 (usually on the skids).  I also became aware that a few others in our small community also started to report the same issues with the full carbon race keel,

Many in the community mentioned exploring other techniques to improve the landing.  Less flaps (not landing with the factory recommended “full” flap setting). For me, this worked reasonably well but the technique did not give me much confidence in the wing as I was still plagued with inconsistency. Some pilots resorted to landing on the control bar skids (certainly not an option for us desert pilots).  Many would describe the landing issue as:  “I got near the ground and the glider just quit flying”.

I should be clear, I can accept that many pilots successfully master the new carbon race keel but I for one struggled to make it work. So much so, I considered simply reverting to the much friendlier VQ, A.I.R.’s “intermediate” performance wing.  I made the decision to sell the VQR and was prepared to order a VQ when I decided to dust off my old VR06 for a local XC (a test flight to confirm its airworthiness for a new owner as this glider was also “sold”). The flight ended with a perfect landing and leaving me asking the question, why so much difference between the VQR and VR06?

The best way I can describe what I believe to be the shortcomings of the Full Carbon Race Keel would be to put forward the understanding that ALL of the ATOS wings are by design, “Flying Wings”. Through their evolution the various models have developed varying levels of dependence on a “tail” to create desirable flight characteristics. From a fix position tail of the early V and VQ to the variable pitch design of the VR, all demonstrate varying levels of dependence on the tail.

The Full Carbon Race keel introduced with the VQR and late model VR’s with substantially greater stiffness and dampening allowed the Race model wings reduce sweep and move our ATOS wings closer to a “hybrid” flying wing, a wing that is now reliant on the tail for overall flight stability. You could say, we are getting closer to that of a conventional sailplane?

The issue as I see it is, our pitch control is weight shift and the tail remains a dampening device and not an elevator as found on our sailplane cousins.  When we come into land, our only pitch control is weight shift.  This evolution and reliance on the tail for pitch dampening has become our Achilles heal. All of the wonderful flight characteristics of the new keel work against you when it comes time to land.

Another deficiency created by the design and the reduction in wing sweep is the forward hang point (4-6” further forward  than earlier models). At the same time, the control bar apex remains unchanged. The benefit of this configuration is improved static balance (I admit the old VR06 was a beast for being tail heavy). When going upright to land, the control bar is effectively 4-6” further back. Any downward load on the upper portions of the DT’s (pretty normal when getting a comp harness upright) will be “at” or “behind” the hang point and certainly not helpful for maintenance of your approach speed (so much so, the new Full Carbon Race Keel tail position has an additional movement, with full flaps, it pitches the nose down to assist in landing trim…. All contributing to a pitch stability that is as solid as concrete 😉)

As I mentioned, I’m sure there are a crowd of pilots out there that are more than happy with the Full Carbon Race keel, but for this old guy the change wasn't working out and I just could not seem to figure it out...  

In Spring of 2023 I received my brand-new ATOS VR14. When I ordered this wing, I ordered it with the original Carbon/Aluminum Keel (same keel as found on the much older VR06). With my very first landing on this wing, my theories involving the Full Carbon Race Keel were reenforced. The first landing was without drama, super easy to maintain trim on approach, predictable landing feel and a pitch that easily reacted to my landing inputs. Truth is, I was shocked just how easily the glider landed!


Ok, is the older version keel perfect? Nope… it’s probably not for everyone. You will find the VR14 substantially more nervous in pitch. You feel more in rough air. Pitch tends to wander in the “bumps”, plus many may have trouble with the near zero bar pressure when the flaps are pulled up and you head out on glide… I compare the VR14 to a race car that has character… and I love it.  

Of course, over the original ATOS racing machine, the VR06, I have benefited from many other good design improvements such as, the small flaps (cleaner and easier to pack), the new quick setup, the updated nose catch system, feels less tail heavy and is a massive reduction in weight (nearly 15 pounds less than my old VR06). The weight reduction shines through when rolling into a turn as the glider has a much-improved roll rate.  I also enjoy getting back on a glider with winglets, not only sexy looking but they really bring back a confident feel to track on glide and a super solid feel in big thermal air. 

Some comparison between the two keels versions (this came as a bit of a surprise…), both keels are as best as I can tell are the same weight (roughly 10 pounds without DT’s or tail feathers).  The Full Carbon Race keel is roughly 14” longer from CB apex to Tail feather LE and nearly 20” longer from hang point to Tail feather LE.  Oh… and the Full Carbon Race keel is going to cost you 2000 Euros more… (important to a cheap sod like me 😉)

The VR14 is likely my last wing from A.I.R. as I suspect I have only a few more years left before I finally “grow up” and find a real hobby! That said, I think the VR14 is the perfect choice to take me through to my retirement from the sport… in 4 or 5 years (???).

I’m pretty sure A.I.R. won’t really care what this one grumpy old guy has to say about their product. My only advice to the crew at A.I.R. is, when spending time trying to make the glider fly better, don’t forget eventually, you will need to land it….

For the Full Carbon Race Keels owners that have adapted their landing techniques,  and are likely happy with the benefits of the keel, koodoos to you... . My buddy “Mike” from Spokane who has mastered his landings on his VQR claims all you have to do is run like somebody is “chasing you with an axe” LOL….can’t argue as his landings tend to be text book perfect. To others that may find yourself struggling, consider getting a test flight on the VR14 with the original keel or even the stock VQ . You might be pleasantly surprised.

If you have a Full Carbon Race Keel and you want to stick to your choice (but you have been landing like a “box of rocks”) it’s probably just technique.… like Mike says… think about that guy chasing you with the axe 😉.

 

Cheers!

"NEW" VR14....

 Say what? .... Yes a new VR14. 

Last year was bit of a loss for me when it came to flying. Not sniveling or anything but a combination of events kind messed up my efforts when it came to flying. Things went off the rails with what seemed to be a minor injury (duffed a landing, tweaked an old work injury), then Covid in June, which turned into a foggy "Long Covid" (or what ever the hell they call the after effects?).  This fouled up my recovery, left me not (IMO) sharp enough to be flying. It left me assessing what to do with season? 

As it turned out the season sucked, I focused on recovery and crewing for my team and made the decision to sell my VQR and my older VR. With both gliders sold, I now had the decision to order a new wing.  

At first I considered an all Dacron VQ (wanting to step back to an easier to fly and much lighter wing). But one last flight on my old VR convinced me that I really missed the track and thermal characteristics of the winglet gliders. Also, one thing I was not convinced about with the latest keel configurations from A.I.R. was the new full Carbon keel of the RACE models.  

Well its a beautiful bit of engineering, I found the tail positions, linked to flap settings and upgraded sweep (forward)  made the full carbon keel harder to land (at least harder for me). Given my experience, I made the decision to take on the option to order a new VR without the full Carbon keel. This option is called a VR14 (based on its certification year).  The tail and sweep are much closer to the configuration of my older VR and because of improvements, nearly 12 pounds lighter and retains the older Flap/Tail compensation system.  Maybe not as elegant as the New full Race setup but still a beautiful aircraft. 

After some delays, stress and of course "money" the new wing arrived safe and sound (Thanks to CargoLux services Europe to Seattle, truck to Vancouver). As any A.I.R pilot will tell you.. .the sweetest sight  you can see is a undamaged crate, on the vehicle and heading home! 

Of course.... now all we need is some flying conditions to test out the baby... will report back when the deed is done...

Aeros, The Need Continues....

 Our Friends at Aeros continue to need our help.


As the completely unjustified action of the Russian Military and its WAR against the people of Ukraine continues, the Ukrainian needs our support. Well governments around the world provide military assistance, the needs of day to day life continue. Please see the message from Aeros below and help if you can.  Thanks..... Martin and Mia

A good kind of Rotor.....

 For Sale, Rotor Havana

If your a short skinny assed pilot, this might be a sweet option for a good price. After a few years of trying to enjoy the benefits of this well made harness I decided to sell it.  I'm 5'11" and 165 pounds, right out on the very limit of the fit.  

If your 5'9" up to 5'10" and weigh less than 160pounds it could be the perfect harness. (Manufacture came very close to making this a perfect harness but missed by just a few cm's...  ) 

The Rotor Havana is super well made but they are a race harness and need to have an exact fit. My fit made for a super clean rig but did not make for a comfortable "butt lever pitch control".  Stuffing on a couple extra layers for spring flying and it simply won't work.  

Zipper setup is the smoothest of all the harnesses. Getting upright is supper easy. I'm right out at the very end of the adjustment, a shorter pilot might find it to be a perfect fit. (Because of the fit, I did add a trim lock system that is easily removed)

I'm asking $1200 USD, essentially "new" with less than 50 hours air time.  I will not ship and I would want anyone interested to pick up and fit the harness before purchase.  I will be in Mansfield (Washington USA)  for the first 3 weeks in July if anyone cares to send me a note via the blog and arrange to drop by... Or if you are in Canada, I will be in Abbotsford through to the end of the month... Cheers!

(BTW, I'm planning to go back to my old smelly Moyes Matrix for now.....)

Keeping it Simple?

 So... the other day I decided to "charge" my flying junk......


Thinking back to them "Old Days" when a helmet was considered an option I get the feeling we certainly have lost site of the concept of keeping it simple! What inspired this little assessment was my new Bluetooth headset system which has 3 devices that need to be charge.... so laying it all out (and looking for another wall outlet to hook another charger to...): 

  • -Heated gloves
  • -Flytec 6030
  • -Android Phone (this is for flying only, my old S7)
  • -Battery pack (just incase anything dies?)
  • -Icom Radio
  • -Headset BT dongle  
  • -Headset BT PTT
  • -BT Headset 
  • -Garmin InReach Mini
  • -Garmin 935 Watch (cool feature that allows you to operate the Mini) 
  • -Not included... my actual phone. 

Finding 10 electrical outlets... not easy! Would not come as a surprise if one day something in this mess does not simply burst into flames....  😆

May 22, 2022 (Back in the Air...)

After nearly 3 years away from Mansfield it was the perfect conditions to get back in air. 

There has been plenty of windy unstable weather around but there was a brief window, a day where light winds, low chance of overdevelopment. Mia stepped up to run the rig (the best tow op in World!) 

The glider, harness, rig had not changed during the Covid time out but I tossed in the usual long list of little changes that could create some challenge. After all, at the base of the tow system is our 1990 Ford F150... you never know when its going to have a snit (like its owner).  We have a new towline recovery chute, new Bluetooth headset system in my kit, some toasty electric gloves that I have never used, a Garmin InReach Mini GPS tracker, first time I've used an Android backup (running XC Tracker)... it was cold so I layered up and was like a stuffed sausage in my harness. 

Conditions turned out to be perfect for a "low drama" flight. Managed a nice 180km FAI in 5 hours, L-Road to Wilson Creek, up past Wilbur to Sherman and managed to pick my way back across the top to L-Road (lift was dying and a headwind was picking up). Top of lift for most of the flight was 8000 asl, tho I did manage 10,000 late in the day.  Radio with its BT headset worked perfect. I fired up the Electric gloves a few times, they kept the cool air from freezing the fingers. Being stuffed tight into the Rotor harness left the Butt lever not working well "butt" I managed ;-).  

The Garmin InReach failed to track the flight? Not sure what was up with that, thought I turned tracking on but? Guess its back to the "manual" to see what step I missed.

Thought it was going to be an easy landing with pretty good breeze at L-Road but it thermal blocked just as I turned final, botched my landing and skidded in like a Euro, no harm to the glider but did manage to tweak my shoulder. Oh well. (Looks like Motrin, Ice, Heat and Scotch for a few days). 

I've decided to end my participation in the OLC (DHV, PG and such... ),  Plenty of reasons for this change but mainly it comes down to not wanting to be part of a "game". Going to shift over to personal goals.  If people want to read about our flying in central Washington it will be their choice. Hopefully this SeeYou snap will work (as a flight summary)?  I do have a online log book with OLC server, might post the link at a later date. 


Thank You to Mia for crewing for this one, I hope to return the favor!

For now, it looks like it's going to be a bunch of windy blustery weather for the next week. Likely won't get big bird back into the air until end of June.  Felt nice to get some airtime....

Cheers

Long Time Away....

 In the fall of 2019, we closed up our little shack in Mansfield Washington. As usual, we felt sad to be ending our time in town but as always, looking forward to "Next" year and another season of flying.  The "lock-up" included all the usual preparations for what can be brutal winter weather. Little did we know just how long it would be before we could return. 

It was January of 2020 when there was a departure from what we had always known as "normal".  Late winter, early spring we would begin planning for another season, typically including a March or April blast down to re-open the shack. The world wide pandemic called "Covid" changed everything.  

Covid the beast taught me a great deal about people and community. I witnessed everything from selfless commitment to the war on this virus to selfish disregard to others and the future. Some governments reacted in a way that any giant bureaucracy can, health and science,  others with denial and ignorance (one famous leader was quoted as saying "it will go away in spring"....).  Right or Wrong, lockdowns, travel bans and border closures became the tools used to combat the early stages of the virus. The first Vaccine would not arrive until early 2021. In that year, Covid did its damage. 

Learning to live with this new era of reduced contact was a challenge for us all. When the virus was not the problem, the effects of social isolation was not far off. My mother, at 94 years of living became confused by the world around her and passed way June of 2020. She had a very long and wonderful life but like many in our medical system at this time suffered from the changes that Covid brought to our world. (I work in the Hospital, Health Care and Hospitality industry, I witness the carnage the "cure" would bring to our society). I'm not saying I know what was right or wrong, I do know the choices were hard. I also know that human selfishness made this world wide problem much more difficult than it would have been had we all worked together. 

For 2020, the option to travel to our property in Mansfield was pretty much out of reach.  Testing and travel/border restrictions made the task so difficult we could only watch our favorite summer place via a fleet of cheap web cams that we left on and connected... at least we had the pleasure of seeing the flocks of birds and deer that took up residence on our property! (including the building and battles for nesting supremacy "on" the cameras ;-) )  Also want to say THANKS to our "Guy" Donny and is crew for taking up the lawn cutting, keeping the place respectable and presentable.

After the somber summer of dealing with the passing of my mother it appeared the twists and turns of fate were not done.  Early September 2020 brought the giant Pearl hill fire. This astounding beast in Washington State was actually the combination of the Cold Spring fire (Near Omak) jumping the Columbia river and creating the Pearl Hill fire.  With an unseasonably strong Red Flag north wind, a careless man made fire on the Labor Day Long weekend sparked near Omak and ran all the way to southern Jameson Coulee.... over 50 miles in days to create the largest complex fire in the history of Washington State.  Right in its path was Mansfield and our summer shack. This is my Video that captured the events of the fire passing around Mansfield.  Amazing work done by both fire crews and farmers in the area. There were structures lost but they were few. Sadly the Cold Spring portion of this fire caused two deaths in a young family trying to get out of the way (my condolences) . Locally, several old homesteads (including L+13, one of our staging areas were destroyed), and a local landmark/home in Saint Andrews were lost. 

Done with 2020, in came 2021.... the Americans had a small problem with the attempted overthrow of their government?... Blame it on Covid, everybody was just a little stressed and had to take it out on something... or somebody? Oh well, democracy at work. 

Spring 2021, travel restrictions continued, Vaccine started to kick in (and so did the anti vac people... ). Trusting the science we got our shots (and tracking chip used by Bill Gates?).... we gave hope to the science. 

By Summer of 2021, a mass heat wave kicked off in British Columbia, estimated to have been responsible for 700+ deaths. The heat wave brought record temps across the Northwest (Hanford WA recorded 120f).  Lyton BC recorded the highest temperature ever recorded in Canada , 121f and the next day caught fire and burned to the ground, setting off a summer of monster fires across the province. 

Fall 2021, things started to calm down when it came to world calamities. Another round of Covid, a wave less than the last leaving some hope.  Then mother nature dished out something special for southern BC and Northern Washington State... an "atmospheric river" , this caused mass catastrophic disasters included severed major highways (shutting down connections to the west coast), biblical flooding in the Fraser Valley (near our home)... and pretty much disrupted life for another 3 months..... oh and that Covid thing, kicked out another surprise... Omicron, dwarfing infection rates greater than every previous wave of Covid.  

Arrive 2022 (holding our breath for "what's next"?). Finally a little light at the end of the tunnel. Travel restrictions were being amended (tho... lets just say people were becoming mentally unhinged and were traveling regardless of the risk... which brought us the smash hit Omicron). Logistically using self administered Covid Testing the option to visit our place in Mansfield appeared doable, so we committed to this two week stay. Of course, not a time of year to go flying but at least a chance to chase out the mice, clean up 2.5 years of dead bugs and dust and turn the shack back into a home. All in all the place did well (and my cheap web cams and network continue to work!).

Ah but not all smiles and roses.... What next? The idiot Putin and his Russian gangsters decided to invade Ukraine. Our worlds newest member of the Adolf Hitler club. He even used dark warnings suggesting if the "The West" came to aid Ukraine, he would start using the nukes. This is as his army lobs shells back an forth over his old Soviet era atomic power facilities (including notorious Chernobyl).  10+million people displaced, 3 million refugees escaping to the west. Madness. 

The Russian army is slowly laying waste to Ukraine,  Our friends in Kiev, the employees of Aeros, one of the few hang gliding manufactures left in our sport, have had to take up arms or flee this senseless destruction. Well the west ponders and pontificates its support for Ukraine, there is hope the the Ukrainian people and their will, is enough to stop this criminal act committed by the Russian leaders and military. 

As to what could possibly be waiting for us in 2022?... God only knows. 

Strength to Ukraine and its people.... (my mother was born north of Odessa)
