      hi 
      Can someone confirm that the old side opening HD canopy is the same size as the
      FWD opening XL canopy please. I have the option of buying a cover from an older
      HD and I have not finished my XL canopy yet to try it out to see if it fits.
      Thanks

      After seeing this mod on this list I wonder why on earth do they use cables as
      standard. I cannot think of one reason not to go for this mod, much less maintenance,
      simple etc etc.
      
      What are others thoughts ......Im building my first wing now and this got me thinking.

      If the canopy was made prior to the 601XL's release then the canopy is a
      different length. However, I did install the older style to my XL and it
      worked just fine, installation takes considerably longer and the older
      canopy will be on and off a lot more for fitting it to the fuselage, as
      you cannot go by the photo manual and measurements. 
      Now It hangs on a wall as I have installed the 650 canopy to the plane
      and I will say that the extra headroom and length are well worth the
      hassle of doing the conversion.

      I've seen that Alex and the only thing I can say is that must have been a smaller
      BRS than the ones I've seen. When I say smaller I mean smaller than the 1350
      which is the one that should be used in a 1320 lbs 601XL.

      I'm installing a BRS-1350 in my XL, and am thinking that placement between the
      instrument panel and the firewall is the best location.  It is a tight fit, and
      I think the European XL's do utilize a smaller BRS.  
      
      Here are the pictures of what I'm considering at this point: http://picasaweb.google.com/Patrick.Hoyt/BRS#
      
      I am going with the 650 canopy, and a simple "day VFR" panel.  Placement of the
      BRS in the usual position in the baggage area is not an option as this area is
      covered with the rear canopy bubble in the 650, as opposed to aluminum skin
      (with frangible cover) in the XL (although I did consider the possibility of an
      installation that would fire the BRS down through the bottom of the fuselage).
      
      Placement of the BRS further aft, behind the baggage compartment bulkhead would
      put it 8 feet aft of the firewall, and less than 4 feet ahead of the horizontal
      stablizer.  CG is the concern there, although granted you could probably fill
      the nose gear strut with lead shot for nose ballast, or build an extended motor
      mount.  My thinking at this point is to keep it as simple as I can and fine-tune
      my airplane's CG by placement of the battery aft, while still allowing
      for the usage of the baggage compartment for baggage.  
      
      I have not seen a 650 (AMD or Zenith) with a front mounted BRS yet, but would welcome
      pictures.

      Pat, what happens to the canopy when the BRS is fired? Isn't the canopy on
      top of it?

      Sabrina,
      
      I have scanned in the spar web drawings from my CZAW set. The drawing set 
      includes the 'standard' set, together with additional sheets showing the 
      CZAW changes. The relevant sheets are labelled 6-W-4 and 6-W-4CZ
      
      I think you can see that the CZAW webs use  80 & 100 degrees, compared with 
      the original values of 78 & 102
      
      I hope this answers (at least 1 of) your questions!

| Subject:  | Re: CZAW Spar Webs | 
      
      
      Dave,
      
      It answers so many questions, thank you so much.   
      
      Much of the reason I am posting these questions is to point out to the FAA and
      NTSB that crashes here in the US of what appear to be CH 601XLs are actually EU
      made/EU re-designed craft that may or may not have been static load tested as
      configured.   CZAW aircraft have been static tested, but the photos appear to
      be of CH601XL design, not of the 80/100 design you have posted. 
      
      I am told that the center spar of the Polk City incident aircraft was made from
      Corus aluminum, sourced in the EU.   It appears that the aircraft had the low
      trailing edge CZAW design made per CZAW and not CH plans.   
      
      Repeatedly, EU builders have told us that their aircraft kits are identical to
      ours and sourced from Canada or the US, but it appears that many are not.  
      
      The LAA appears to have decided that all "XL/650" center spars need to be reinforced
      rather than tested.
      
      It appears unfair to lump CH601XLs built to LSA standards into the CZAW and 650
      category which utilize this new spar set.  
      
      So too, the LAA makes no differentiation between PH and FH aileron, no differentiations
      between center spars which already have 4 reinforcing uprights and those
      with 2 or none.

      OK, for those interesting the parts for the aileron rods (rod ends and rod

      Hello Gig,
      -
      You are right the correct "list" is important.
      -
      In my own opinion,- given some personal experience I have in homebuilding
      ,- The share of building information is VERY important for anyone, both N
      ewbie and "Experienced" builder, First note-that we all have to admit, th
      at we keep learning all our lives.
      -
      I think that there is an important "line" here:- 
      BEFORE Internet- and AFTER internet (email lists in this case).-
      -
      I remember (prior Internet times)- that when I had a serious concern abou
      t some detail in- the plans (or when choosing an airplane to build).
      First I need to find out Where to look for the information (through magazin
      es-and articles mostly)- then send a letter to the-magazine editor fo
      r the data of the plane and designer, wait weeks-for his answer, then wri
      te to the designer, builder, "kit factory" (some of this " kit factories" 
      -was the own designer's -garage), then wait for an answer (if they feel
       like writing overseas) for another month ot more.-- 
      -
      In short, -for some "to be" builders, could-take several months to gath
      er just the basic info for starting,-only to be kind of convinced, -tha
      t this was the plane of our dreams...
      -
      Now with this modern internet time, a first time builder,-Newbie with no
      -previous background in aviation,- all he needs to -do is to "google"
       some information (truth or false, we find plenty of both in internet)- a
      nd- subscribe to the specific airplane list, and Bingo!-
      -In a few weeks, he is an =B7"Expert" that can even advice "Newbies"- f
      rom the use (or not) of Scothbrite, up to the way-to modify the airplane 
      to prevent flutter :-) :-)- 
      -
      About "flying advice"- and flight simulators...- Thats another story-
       :-)- :-)
      -
      Saludos
      Gary Gower.
      Newby builder all my life.

      Gary,
      
      The big problem with the multiple lists is for the newbies that find it on 
      the
      web forum instead of via the e-mail list. They come find a 650 list with ou
      t
      much information and never return.
      
      I know I couldn't have built my plane without this list or one like it.

      Dave,   Thank you.  
      
      It appears that the CZAW design not only changes the spar web set to 80/100, it
      substitutes shorter AN-470-AD-5 rivets in 32 positions.  They are only 1/32 shorter,
      but why?

      The rear portion of the canopy would be in the way if the BRS were mounted in the
      baggage area (assuming usage of the 650 canopy), which is one reason why I
      want to put my BRS up front.  The bracket that the rocket tube is mounted on is
      bolted to the cabin side of the firewall, and the rocket fires up through a
      frangible cover on the center-front portion of the forward top skin (ahead of
      the front of the canopy).
      
      You can get an idea of the available space between the firewall and the leading edge of the 650 canopy by looking at this photo: http://www.zenithair.com/zodiac/608/650ata2.jpg 
      
      I don't know what would happen to the canopy if the BRS were fired in this front-mounted
      scenario.  My main concern would be that the parachute not get "fouled"
      on it.  
      
      Again, this is what I'm considering doing on my own airplane.  I have not completed
      the install, so it remains unproven at this time.  I am interested in seeing
      what other XL/650 builders have done in this regard, and building upon the
      proven success of others.

      Sabrina,
      Yes, all like you describe.  The second set of stiffeners was not on my drawings
      but I added them when I went with the dual control sticks.

      Gig,
      I'd like to see the data that they made these judgements from too, but from what
      we all know I think they're reasonable.
      1.  You've got something statistically significant happening with XL crashes.
      2.  Even the EAA recommends control surface balancing because unbalanced control
      surfaces are PRONE to flutter.
      3.  Reports have been made by members of this list of experiencing flutter.   I'd
      call that evidence.
      4. There is is also some evidence (not everyone is convinced) that some of these
      incedences happened in straight and level flight. 
      5.  Zenith proactively put out warnings about maintaining control cable tension.
      (I think they said to prevent flutter, not sure on this point)
      None of this is proof that any of the failures were due to flutter, but some might
      conclude it's enough evidence so that some precautions should be made against
      that as a possible culprit.
      I hope Zenith has some recommendations out soon,as I'm about to begin assembling
      wings.

      An EAA buddy of mine, we met working at the Arlington
      flyin 5 years ago, spent December in New Zealand.
      He was fortunate enough to fly in a number of airplanes.
      He took aerobatic lessons in a Robin. Chris Heintz
      designed the Robin HR200 in the 70's.
      http://www.pilotfriend.com/aircraft%20performance/Robin/HR200.htm
      As my friend remarked, you can see the 601 in the Robin.
      I posted the picture he took,
      http://www.cleanh2o.com/633z/robin_small.jpg
      and a high res one if you want details:
