The Happy Flyers product I mentioned in another post used two, vertical dipoles mounted at the leading edges of the wings. As I recall, they arranged mounts that allowed one to remove the antennas when not on a search mission. They weren't hard to install and only 40" over all.

I have King (2) KX-155 navcom, one with ILS, Audio panel, ADF, and Xponder, IIMorrow Flybuddy 820 GPS, Flightcom intercom, and Bose headsets. Everything works excellent. The Transmitters always do a fine job, even at marginal altitude/range. Everyone reports we sound professional, and handling by controllers seems to confirm that. Plan to upgrade the GPS to a IImorrow GPS50 in the near future to get the moving map, but the 820 works well and is easy to use. It can drive the Navaid autopilot and watch time distance, direction to other stations/airports along the route. It does it so easily, we're always using to keep track of exactly where we are. Even with the DUATS flight planner, I can't draw a line on a sectional that is as accurate as the autopilot will fly the plane, typically within less than 0.2 miles off course. The 7 antennas are Antenna Dynamics. For installation, I struck a deal with a local avionics shop, I built up the trays and harness, $50 for bench check of the assembly, I installed in airframe, final checkout as installed, an activate warranty. The total cost was no more than $200 than the best price I could find anywhere (sometimes they send you used equipment or other problems), and I got all the handholding that anyone could want. They encouraged calls with questions. Make sure your warranty activation is covered. Most manufacturer's require one of their dealers do the installation, or at least supervise it. From: "L.

I think for part 91, about anything goes. No redundancy required. The new single engine IFR rules for Part 135 requires redundancy, either dual alternators or alternator/vacuum redundancy. This summer I flew a Bonanza with a HSI. The HSI is electric, and replaced the vacuum DG. The second alternator was placarded as "removed for repair" I think it had been that way for most of the last couple years I have flown that airplane.

Wayne Hicks] Ron Alexander wrote a very informative article entitled, "Rules and Regulations of Airplane Building". The article was published in the May 1997 issue. A must read for all of us! I will attempt to paraphrase from that article. Please reference this article yourself in case I say something wrong. The bottom line --> installing additional IFR instruments after flight testing will involve applying for and getting a new airworthiness certificate. My two cents--> Installing everything and working out the bugs later is better than the downtime while waiting for the FAA paperwork to catch up to you. The FAA will issue you two airworthiness certificates -- a Phase 1 for the flight test phase, and Phase 2 after flight testing that's good for the duration of the airplane's lifetime. Important! Phase 2 lists operating limitations that go into effect upon completion of the flight testing. You are allowed to make minor changes to your airplane throughout it's life, but any major changes that are made to the plane as defined by FAR 21.93 require inspection by the FAA prior to further flight. A minor change is defined as one that has NO appreciable effect on the weight, balance (LWH: Bingo!), structure, or anything affecting airworthiness. If a major change is made, you'd have to notify the FAA in writing, provide the details of the change to "ascertain whether or not an inspection will be required." (Note: I'm not clear on whether R. Alexander is implying that "you" ascertain and decide, or whether the "FAA" ascertains and decides. I suspect the FAA ascertains and decides.) Based on Ron's article, I can only assume that since additional panel instruments would affect the weight and balance of your aircraft that you'd need to follow this procedure. You need to be VFR legal for flight tests (the article says that, too!). You don't need IFR-everything for test flights, but installing after receiving your phase 2 certificate might lead to some downtime waiting for the FAA paper trail to catch up to you. (Marc Z--> If I did the leg work to get Ron's and Sport Aviation's permission, could you post this article on your website under your reference documents????)

Part 91 rules are very basic. It's sort of like buyer beware...only it's flyer beware. A vacuum system and an electric system are not redundancy - they are 2 separate systems and if either fails, neither replaces the other operationally. The flight is in big time trouble in hard IFR. Most of us on this forum probably can not afford to have all the systems necessary to make hard IFR flight practicle. I would miss most radar and adequate deicing equipment, not to mention true redundancy, i.e., 2 or 3 of everything including engines. Soft IFR (no freezing precip, no thermal activity and 2000/3 along the route) is reasonable and doable any day single engine, single Cozy pilot.

Probably the DG and horizon will use more power than the T & B.

Some time later a huge night time thunderstorm came through and the next morning the ramp area was covered with what appeared to be cotton.

How do they sound? Are they easy to wire? About my progress, I am going to paint my bird next week-end (Sunday , Monday and Tuesday). I decided the following for my painting: -Use the help of an aeronautical professionnal painter. -Set up a painting tent in my garage ( No way I can move out my fuselage before it is fully ready to fly ) -Use Polyfiber products ( Smoothprime, silvershield and flight gloss ) for several reasons: * It was recommended by Ron Alexander via an Email exchange. * It was easy to find in Europe via Airtronic ( Charleroi Belgium). * It is non hazardous and I am painting everything at home with close neighbours also. * I figured I should use the same brand of paint all through for better durability an better bounding caracteritics to the structure. I also had a hard time finding the proper UV barrier paint in France. -I will tell you how it went next week. I am planning on going to the Chicago area from April 3 to 6 mainly to pick up and ferry back my performance prop to France. I would be happy to meet with any Cozy builder that lives very close to Chicago (I have no time to drive very far from there ) to say hello and exchange ideas .In fact we would be 2 Cozy builders ( Gilles DESGRUELLES and I).If this is possible feel free to drop an E mail to me so we can set up plans.

At night, over water with poor visibility and IFR, I want the altitude. In the mountains and flat land with towers, terrain clearance is FIRST. Put all the flight instruments where they belong, in front of the pilot, in a standard configuration. This will enhance safety when flight training in addition to others flying the aircraft.

Did someone give you one? First generation GPS's are now becoming available. The do not have moving maps or IFR certification, but are excellent useable units. I have a IIMORROW APOLLO Flybuddy 820 panel mount GPS that is 5 years old. Yesterday coupled to the Navaid autopilot, it did all the steering of the Cosy Classic from Sun N Fun to Cleveland, Ohio (5.5 hours at 207MPH cruise, 1 stop). The maximum off course was .2 miles. And while it was doing this, I used find the nearest airport or VOR feature to keep track of exactly where we were. It will handle this second function without loosing the original task of maintaining the great circle route for a 700 mile leg. I update the data card annually at OSH. Push another button, turn a knob and there is a huge data base of runway, frequency, fuel, etc. info at your finger tips. I hope to upgrade to the IIMORROW GX50 GPS this summer, at which time I will sell the above unit. I just searched the current trade a plane to find what would be an appropriate selling price, but there wasn't any. I heard it might be around $1,000. The new with IFR certification is around $4000. The EZ's are a long haul Bird, and for best useage you should plan IFR, leaving panel holes, install antennas, etc, and then install equipment as you can afford. Do not rely on GPS alone. There was recently an incident where a part of the New England area GPS was jammed by a government agency, where someone forgot to turn a switch off. I have 2 King KX-155 one with ILS, an ADF, and marker beocon in addition to the GPS for navigation. I fear thunderstorms, low ceilings, poor visibility, and icing. But most IFR is popping through a thin cloud deck, a whole lot safer than scud running. On the way to Sun N Fun, Did an ILS into Rome, GA. with 600' ceiling and 3 miles visibilty. Left after lunch and fuel, climbed to 5000', was shortly 3000' broken, tops a 6000'. Popped in and out of the broken clouds, was almost able to navigate visually. Trip home was good VFR, though bumpy from central Georgia to Ohio River. Date: Sat, 09 May 1998 00:00:25 -0700 From: Eric Westland Subject: COZY: ELT Location?

DIscussion with the ACK people today: ELT, antenna and remote control wires should not be located near radio wave generators (transmitting antennas, heavy wires (battery), strobes and power supplies, and the like). They indicated they would return the ELT within 3 days, and probably would repace a standby transistor. They thought a radio wave was causing the activation.

I assume you will have wing tip strobes, in which case there will be high voltage/current (relatively) in the wires going to the strobes. Probably the top of the turtleback would be best, but its not that critical. I have wondered about the gimbals, and thought they would be needed to give reasonable headings in a steep bank turn. should be able to hook the serial output to your PC and possibly with a terminal program in capture mode get readable output and by keeping the unit level, and simulating bank at various directions will quickly determine whether the gimbals are needed. The FAA requires an approved compass as a minimum, and considering the range of an EZ a good one is mandatory. Canada IFR requires wiskey glass, not vertical card. Anyone planning IFR in Canada should check their requirements, they are very specific in the radio, navigation area. If there is enough call for, I'll prepare a summary. Have considered compass output to a small embedded system computer (Basic Stamp variety) with an analog output to drive the Navaid autopilot. Jim Ham, Porcine Assoc. GPS interfaces are of this variety, except use GPS ground track for heading info. If interest in this area let me know, planning something, but haven't finalized.

I have written code for the PNI Vector2X compass module for the handy board (robot stuff), and it is pretty good. I havn't used the one with a display, but I assume it is the same basic guts. Works like an RMI, and is mostly self calibrating (there is a manual calibration mode, you set it down, punch a button, rotate the thing 180degrees, and press the button) (See: ) The gimballed version won't help in coordinated turns. The gimballs will only correct for changes in angles relative to G forces.

Date: Fri, 16 Oct 1998 19:27:50 -0700 I have to agree with Bill. I don't know why anyone would use a Loran with GPS as inexpensive as it is.

Ernesto; I had a loran in my long EZ for a year or so. One evening I was nearly out of fuel at sundown over my destination in Colorado only to find myself over a mountain top with no villages in site. That thing almost killed me. They lie like a rug!

On the data sheet it seems to offer many features at a very good price. What is it really ?

I have decided to get the AV-10 unit that also has fuel flow information. Rod Long, the president of the company, has offered a group discount if enough of us agree to purchase the system. If you are shopping for instruments, take a look at www.rose.com/~afa where you can see all the details of the system. If enough of us get together we can save some money. Please email me directly after you review the web sight and would like to purchase the system. I will be happy to represent the "group" and negotiate the best price I can which will depend on the number participating in this purchase. I hope to purchase this system before March of '99.

I purchased a narco mk 12D cessna slide in replacement from a tornado damaged cessna. I have tried all the radio shops that I know of including several salvage yards. Tim
