  1. Money is the only limit to a panel. You never said what your budget was. If you had enough $$$$ your could put an F-16 heads up display in that would be way cool. On the other hand all your really have to have is an air speed and altimeter, tach, handheld com, gps and some engine instruments and you can go all over the usa.

    STeve building on

    Reminds me of a past professor that demonstrated the paperclip vs. tie-clip analogy.

  2. Hi All,

     

    Regarding the use and design of LED systems, there is a good post at this link:

     

    http://www.eaa724.org/MeetingsEventsYear2004.html#anchorGarratt

     

    scroll down a bit until you see the discussion about LEDs. There are some useful links regarding the lighting requirements. Quoting that article:

     

    "Basically, you need 360 degree strobe coverage horizontally, plus 30 degrees of vertical visibility. The side position lights need 110 degrees of horizontal coverage, and a white tail position light must be seen from 70 degrees aft."

     

    I just built a nice strobe/nav light system for my VariEze, total cost was about $70. I purchased 2 Luxeon 480-lumen LEDs (min FAA req't is 400 lumen) and made a 2-inch square flashing circuit out of about $20 in parts from Radio Shack for the strobe system. (total parts: 1 IC + 3 resistors + 1 + the 2 LEDs). I used specific values of the resistors & the capacitor to obtain an 80 milli-second flash every 0.8 seconds.. a nice 'strobe' effect... it's an easy calculation to tweak it to whatever you desire.

     

    The wingtip lights required just one 75-lumen LED and 1 resistor per side, tied into the 12V bus/switch/circuit breaker.

     

    My system is on the bench now, I'm currently working on the mount/installation into the plane now. I'm putting the nav lights on the canard tips, the strobes on the wing tips.

     

    I'd be happy to post the entire parts list, flashing circuit, etc. if anyone is interested.

    You Betcha!

    Post your list please

  3. That is a good idea! I should have done that - i used 1.5"x1.5" 4130N barstock and spent a lot of time on the Bridgeport turning the handles. I went to .150" with a nice fillet radius.

     

    If using aluminum I recommend going to 3/16" material to lower the bearing stress and prevent brinelling the 1/4" fastener holes.

    Thanks!

    Much appreciated!

  4. Thanks Drew and Kent!

    It's gonna be hard to tell folks I used a precise, delicate tool, such as a sledgehammer on the plane.

    But it looks like it's the safe way to go.

    BTW kent, is there a CP reference for steel extrusions?

    Hey maybe the Cozy Girrrls might find these extrusions worthwhile to manufacture.

    Thanks so much for the advice.

  5. Fellow canardians,

     

    I am relocating my ship's brake master cylinders and installing them behind Dale Martin's rudder pedals.

    I am also upgrading the ship's engine to an IO-320.

     

    The Long EZ plans call for the original plans brake cylinders to be connected

    between the aluminum engine mounts on the firewall.

    The lower mount carried the end of the brake master cylinder through a bracket-CS73, while the top anchored a lever-bellcrank, which converted brake pedal motion into a "push" on the brake cylinder actuator.

     

    Doing this mod on my Long-EZ, leaves an unused 3/16" hole in the aluminum "L" angle extrusions at (as a bonafide COZY mk.4 builder flyer suggests) near their point of max bending - not a desirable trait in an engine mount.

     

    Has anyone ever heard of a fix to get rid of this hole without doing

    major surgery on the extrusions, essentially replacing them?

     

    Filling the hole with a weld will probably conduct heat to the nearby

    spar and anneal the aluminum mount.

    Reinforcing it with an attached piece of aluminum relies too

    heavily of the attachment method of the reinforcement piece - epoxy?

    rivets? (more holes).

     

    My instinct says reattach the "old plans" bracket, without its associated brake master cylinder with its "old" countersunk screw.

     

    Any ideas welcome.

  6. Agreed! Most folks are upgrading to this system ..... not swapping it out. You might get lucky and get one out of a wrecked plane or an abandoned project. I'd be checking eBay otherwise ....... Jack is the source.

    Not so fast buying stuff outta wrecked planes.

    I got a deal out of a LE that wrecked a few years ago, seller was an honest fellow, and warned me upfront ( I thought I could fix it myself ).

    Sent it back to Jack, there wasn't a straight piece left on the assembly (that was before I tried to fix anything),

    I essentially got to use it as a rough core.

    Saved a couple hundred bucks after all was fixed and or replaced over a new one.

    Go new.

  7. I don't plan on doing any hard IMC flight; at least not by myself and certainly not in icing conditions. While I realize that I will be capable of doing it, I will be far more likely to never even take off if it looks like that is a probability. It isn't worth it. If I have to get there that bad I'll fly commercial. I'm really looking for a way to still get to fly with the storms that come through Georgia. In the Spring/Summer/Early Fall, it isn't uncommon to have bands of storms come through in the afternoons so being able to fly through the clouds and shoot ILS when it rains will be invaluable.

    Exactly, well said, that's what my wife and I plan on doing with our ship down here in Florida.:cool:

  8. GOTSL Got slow

    UNOIT You know it

    Paraphrasing the NTSB, A jetstream crew stalled in IMC over the FAF and ended up just east of Runway.

    January of 1994

    You gotta stay on top of your game if you're gonna fly in the goo.

    Single pilot IMC is tough, not being proficient is asking for trouble.

    The people I know, fly the LEZ because its relatively inexpensive, tack on the required practice to stay current in IMC, and you're looking at added expense.

  9. Now back to the dead horse about not really flying IFR unless you do it all the time and are a "Professional."--- It would be interesting to do a study on frequency of accidents of actual IFR flights, that are flown by the "amateurs" who filed an IFR flight plan, compared with gen aviation accidents as a whole.

     

    While you are at it, compare the results with accidents in the same arena flown by "professionals" in light planes, in general.

     

    I for one, would be interested in the results.

    Ummmmmm, :confused:

    "Professional"? vs. "Amateur"? Where did that come from?

    Staying current, and proficient before you go into the clouds with a very agile airplane is, I'm at a loss of words----------simply, life extending?:rolleyes:

  10. Exactly,

    I believe the LEZ or Cozy models are very capable of IFR-IMC flying, but to shoot ILS's, execute missed approaches, holds, circling and practicing partial panel takes a tremendous amount of work and dedication.

    IMHO, the plane might be capable, but the pilot has to be current and qualified to go out in the goo.

    Take look at the ILS approach fixes into KCMH for 28R?

    Anybody heard why they got their names?

  11. If hard IMC with any ice at all then you may want to consider an aircraft with anti/de-ice capes to get you out of it. My long will be IFR capable to primarily get me on top and shoot the occasional ILS to minimums in warm air as well as maintain instrument proficiency when Uncle Sam stops paying for my fuel.

     

    Hope this helps.

     

    I'd hate to think what a little rime ice would do to the canard's flight characteristics. Anyone know?

     

    A year ago, I had a long talk with a couple flying a heavily IFR equipped RV-6. they were on their way from Minneapolis to New York.

    If I remember correctly, it was somewhere in Minnesota in winter.

    The freezing level was at 1000 feet with overcast layer two thousand feet thick.

     

    Their plan was to scud run until they found a hole to pop up thru.

    They changed their minds when I asked them if they had parachute like this Cirrus. Eventhough I doubt it would have helped them around 3000 feet.

    A true PIREP.

     

    MGM UUA /OV SCD 270004/TM 2200/FL090/TP SR22/IC SVR ICG 077-090/RM ACFT WAS DESCENDING BY PARACHUTE DUE TO SEVRE ICG BUILDUP

  12. If you want to be Maverick and Iceman and goosestep around the ramp..cooool. We will be happy to give you wide berth as you slick back your hair and make your way to your Ninja 1000's.=] There is something for everybody here and for the 1%'ers who want to wear a chute....its groovy. I think the majority of us are not with it there.

    And by the way...us fat guys look silly in tight Airforce style flightsuits- so I'm saying all of this VERY tounge in cheek, because I wish I really could be like you guyz.

    I could get good at goosestepping, if I practiced I think.=]

    And the retracts definately do help the 'fighter aircraft' look. Those have to be a part of the whole scenario.

     

    How about Nomex flight suits complete with cool patches, gloves, and a helmet too?

  13. Save yourself some time and effort.

    Steve at Eureka will CNC hotwire you some foam cores for a good price.

    I have almost finished up chapter 20 on my left wing.

    Those cores were so pretty, I hated to skin them.

    Very accurate, clean assembly.

    Only thing I regret, is not spending more time on the jigs.

    I'd CNC cut those if I could, along with some improvements I discovered along the way.

  14. Excellent job on the foam cores!

    Good value excellent quality.

    Thank you for cutting them before you left.

    Here's a great example of ingenuity filling a niche.

    My wife and I thank you for your family's sacrifice

    Fly safe and tailwinds home!
