If you know the force and body length and length extended and retracted, you local RV parts supplier has catalogs of these things to chose from.  Fairly reasonably.  The "ends" are often replaceable, so if you are replacing one already installed, you can often remove the tips and use a new strut of the right force and size.

Hangar Flying / Rutan Birthday Party
« Last post by dorr on May 28, 2018, 02:32:28 AM »
We are gathering at Couer D'Alene on June 29th & 30th for Burt & Dick's Birthday party - and there is always a great congregation of canard airplanes at these events.   I have been asked to provide responses to the Rutans if you would please RSVP to me: David Orr David@CanardFinder.net (There are well over 100 people contemplated, so please do inform me if you can join.

If this is still an open topic.  If you get the geometyry sorted then these guys have preloaded gas struts that you "bleed off" until you get just the load value that you need.  They ar e based in UK but there must be similar things over there.  PG

Hangar Flying / Kanab Rutan Fly-In 2018
« Last post by atfloyd on May 16, 2018, 09:43:46 PM »
Hello Canard Pilots & Enthusiasts,

We had a great time with everyone last year in Kanab, and we are preparing for the Labor Day weekend event again this year. The Rutan Kanab 2018 Fly-in will take place September 1, 2, and 3 ( Saturday, Sunday, and departures on Monday).  It’s become popular with a number of people to arrive a day early on Friday, so we have coordinated with the hotel to block the rooms for the nights of Friday Aug. 31st, Saturday and Sunday Sept. 1, and 2nd.

If you haven’t been to the Rutan Kanab Fly-in, KKNB is a small town airport.  The three main reasons people say they love coming to Kanab for the fly-in: 1. The laid back atmosphere, 2. The scenery, and 3. The timed event.  Every year there seem to be between 20-30 planes that make the trip to KKNB, along with folks who drive in. We don’t plan a lot of scheduled activities, so that people can choose what they want to do, including plenty of airport “ramp talk”.  A few planned group activities that bring everyone together are typically the outdoor pizza party, a group fly out on Saturday morning, the timed event Sunday morning, and a group “awards” dinner on Sunday evening. There is plenty of free time during the 3 day fly-in to explore Kanab, Kane County, and the surrounding national parks and attractions. More “back seat” and “right seat” Canardians are attending Kanab each year, and there are activities available in the area for you if you’re not interested in hanging out at the airport.

For 2018, we secured lodging with the fantastic Canyons Collection hotels again ( three separate but commonly owned properties in close proximity ). We received great feedback from attendees last year about the lodging, and from the hotel management about the event. The 2018 room rates for the Rutan Kanab Fly-in are as follows:
The Canyons Lodge $99-$169/night + tax  (*includes continental breakfast) 13 rooms available
Canyons Boutique Hotel $179/ night +tax (*includes breakfast buffet) 20 rooms available
Quail Park Lodge $139/night + tax (*includes continental breakfast) 10 rooms available
           *Please do not book online*.

Please book Canyons Lodge as the primary hotel before the other two.  Identify that you’re with the Rutan Fly-in group when you call to make your reservations. Any hotel based social activities will be held on the grounds of the Canyons Lodge in the common areas. Also... book as soon as you can, because they’ll release our block of rooms fairly soon, after all... Summer is peak travel season. The 72 hour/ 3 day cancellation policy will apply to reservations, even though issues crop up last minute.

If you’d like to see the properties, the website is www.TheCanyonsCollection.com
(Again, *please do not book online*. ) Travis is the owner, and he’s the only independent hotelier left in Kanab. When you’re ready to book a room you’ll need to call them at 844-322-8824.  Their desk staff have all been briefed about our group event, and will be able to take your reservation by phone.

Because the event has grown in size, we have outgrown most venues in Kanab for our Sunday evening awards dinner. We have been exploring our options for alternatives.  If someone has a suggestion for the awards dinner that will accommodate 60 people, please email or contact us ASAP.  There is no written schedule of events available until we secure a plan for the awards dinner. We are hoping to have the Kane County Visitors Bureau bus available again for transportation to and from the hotel/airport.

Blue Skies,
Laura & Allen

Thanks Joe.  Need to have a friend measure it for me and get the part number....

While those who like the vortex generators are OK with small reduced top speed and a much harder to clean surface, it would seem the easier route would be to remove the vortex generators - the CAA has approved the Long EZ without them, right?

Yes we are luckier in the US to be able to experiment by simply flying off major modifications and trying anything less.

Hi Marc, I really appreciate your helpful response. We don't have the Experimental category; ours is a Permit to Fly issued by the UK Light Aircraft Association delegated to it by the CAA. Three test flights were completed, one at 102.7 and two at 101.7. Yes, we need to cover 97 to 103. Our 'stall' speeds, 50  at 1466 lbs and 61  at 1600 lbs were all KIAS. I read an article that illustrates the difference between certified and non-certified aircraft as regards VGs, the former being massively more expensive to take account of all their testing. Seems we shall be doing much the same testing.

First, let me suggest that you post safety related questions of this (or any other) related nature on a forum that has more members, viewers and activity - you'll get far more response and from far more people.

Despite the aircraft having done three test pilot flights, I have to prove the safety aspects of the installation and the effects on 'stalling' speed - it nods at 50 kts.
At what CG does the nose bob at 50 KT (I assume KIAS - you don't state whether KIAS, KTAS or Kt GS). At what Gross Weight does it bob at 50 Kts (I'll assume IAS for expediency)? Have you tested the stall speeds at forward most CG (97") all the way back to aftmost CG (103"), and with weights from minimum achievable up to your proposed 1600 lb. MGW? At all intermediate combinations as well? And accelerated stalls, from 0 to 60 degrees of bank? Once you've done all that, you'll actually know the characteristics of your plane - until then, you don't.

I found that Micro Aerodynamics declare, and issue a placard, of airworthiness provided no more than 5 VGs are missing.
At least in the USA, there is no such thing as "airworthiness" for experimental aircraft - only type certificated aircraft can be "airworthy". Don't know if it's the same in the UK. In any case, Micro Aerodynamics can have no knowledge of and can make no categorical statements regarding the safety of a plans built, one off experimental amateur built aircraft - them saying "up to five missing VG's" is a good start at understanding the possibilities for your plane, but not particularly meaningful.


I can supply photos of the installation but am short of a suitable/professional diagram of placement and chord etc detail that would satisfy the scrutineers  Can anyone point me in the right direction?
So here:

http://cozybuilders.org/cad_files/

down near the bottom under "Miscellaneous" are some PDF's of VG size and placement used for COZY MKIV's. The Long-EZ would be essentially identical, measuring from the strake/wing intersection for the wing placement and from the fuselage side for the canard placement.

But whatever documents you provide, only a full test program and results presentation will show that the plane is, in fact, safe within the approved operating envelope under all circumstances.

I need help. I have a Long Ez in the UK and have completed the airtest to increase the MAUW to 1600 lbs. The aircraft is fitted with VGs on the canard and wing (I bought it like this). However, a local difficulty with the authorities means I have to submit paperwork to regularise the VG set-up. I also have to come up with specific CG calculations with min front seat weight. Despite the aircraft having done three test pilot flights, I have to prove the safety aspects of the installation and the effects on 'stalling' speed - it nods at 50 kts. I found that Micro Aerodynamics declare, and issue a placard, of airworthiness provided no more than 5 VGs are missing.

YMMV because it depends on the geometry of the installation but I used the Aircraft Spruce part number 05-01177 in my Long-EZ.
