I did not think it made much difference until I flew one without it.

Then Rotec adds a rather pragmatic statement basically saying that the Rotax recommendation isn't practical and 10% is what's widely available. ________________________________ Message 4 _____________________________________ Time: 08:06:39 AM PST US From: Michel Verheughe Subject: Re: Kitfox-List: off topic - Date time note --> Kitfox-List message posted by: Michel Verheughe On Apr 17, 2006, at 12:47 AM, Mr NELSON GOGUEN wrote: > I'm still with the guy figuring how to get polytak cement off my > fingers Here is how: Put your fingers in a space/time wormhole after setting your photon accelerator to ... about, 42.

Have put about 4 hours on it in the last couple of weeks We have a small engine miss if we cruise at 4600 to 4800 rpm. If carb heat is pulled the engine smooths out perfectly.

Basically, your mixture is set too rich, and the leak is leaning out the rear cylinder to the correct mixture. Check and double check the intake tracks post-carb. Re-torque the intake bolts, even get new gaskets.

The intake on the rear does an immediate 90 degree bend with a very short distance. The front intake is a longer distance kind of straight. Hence the leaner on the rear and richer on the front. Also, Pierre Landry told me that if you remember him. He spent 6 months of the year in Austria at the Rotax factory and 6 months in Canada working for Rotax there.

If the plugs are black in the front I sure do not want to richen the mixture to simulate the carb heat, I figure it will worsen the problem but really do not know.

I'd like some help de-bugging, if I may. Configuration: Rotax 582 grey head w/ 3-phase regulator wired per Z-17. GRT EIS tach wire connected to yellow alternator output wire. First start: Tachometer reads 0. No variation in voltage switching alternator in or out, regardless of RPM. Voltage about 12.9V. Disconnect regulator from alternator. Measure ACV across alternator and get Rotax spec values. (~14 - 55 VAC depending on RPM.) Re-connect regulator input wires and disconnect output wire and measure voltage between it and ground: ~5 VDC invariant with RPM. Note that the EIS RPM is now working. Re-connect the output wire and clip DC volt meter between the regulator output and ground: ~ 14.1 VDC at idle, decreasing to about 5 VDC at higher RPM. EIS RPM is 0 again. Basically I'm clueless as to how to diagnose whether the charging system is working beyond the alternator output. Any help would be appreciated. I think whatever's influencing the charging is probably inhibiting the EIS RPM input, as well. Thanks, Guy Buchanan K-IV 1200 / 582 / 99.9% done, thanks mostly to Bob Ducar. ________________________________ Message 19 ____________________________________ Time: 06:57:27 PM PST US From: Malcolmbru@aol.com Subject: Kitfox-List: anfib sport pilot malcolm --> Kitfox-List message posted by: Malcolmbru@aol.com We=E2=80=99ve been Duped, =E2=80=9CAmphibians Need Retracts=E2=80=9D The committees worked vary hard to get Sport Pilot and Light-Sport Aircraft right the first time. As with all complex rule changes, we missed the mark. But, it is not our fault! Really! There were many discussions on retracts for amphibious aircraft. We knew we had to have something that worked. The answer seemed easy. Call them=20=E2=80=9C repositionable gear=E2=80=9D. After all, that is what happens. These gear are not changed just after takeoff or just before landing. They are never changed=20just for performance improvement. They are changed to get to a new mode of interface with the earth, both wet and dry. How can you say the Buccaneer pilot who leans out and hangs his gear up on=20a hook, stretching the bungee cord that keeps it attached to the socket, is doing a complex job? We thought we had our FAA counterparts convinced. I briefed hundreds of people, =E2=80=9Cnot to worry=E2=80=9D FAA understands and we will get it done. While in reality, =E2=80=9CWe=E2=80=99ve been duped!=E2=80=9D What happened? How could this be? It was a simple change just one to thing to understanding. For us =E2=80=9Crepositionable means simple non-performance-enhancing gear moved in-flight.=E2=80=9D But for =E2=80=9Csomeone=E2=80=9D in FAA, repositionable means, =E2=80=9Ccannot change in flight=E2=80=9D. See the Federal Register, 69 FR 44801, it reads,=E2=80=9D Repositionable=20landing gear remains fixed in its position from takeoff through landing=E2=80=9D. =20That is all it took! Everyone, including the government, knows that an amphibian is safer to emergency land gear up. Everyone, including the government, knows that=20the reason to carry gear is to use it. A wheeled carriage will achieve the same thing as government=E2=80=99s definition of =E2=80=9Crepositionable=E2=80=9D. Everyone, including the government, knows that a Sport Pilot can handle distractions such as radios, flaps, fuel valves and GPS, but somehow moving a lever is too much. But, wait, there is hope. FAA personnel have promised that this is being addressed with all haste. Read, =E2=80=9Cat the speed of government.=E2=80=9D That means a least a year, maybe more. Meanwhile, manufacturers are dying while they wait to sell their product. Worst yet, pilots go untrained because we cannot bring in legitimate ELSA amphibian trainers. Owners cannot fly legitimate Amateur Built amphibians because their training as Private pilots cannot be applied to their Sport Pilot privileges. How do we fix this NOW, before it is too late? The answer is a bridge exemption that will let us function now and the rule can catch up at the=20=E2=80=9Cspeed government=E2=80=9D. Mermaid was the first to apply. On April 4th they were granted the exemption. FAA personnel have said =E2=80=9Ceveryone should file individually for the exemption=E2=80=9D. Right! Three hundred new exemptions moving=20through the Federal Register at the =E2=80=9CSpeed of government=E2=80=9D, not my idea of a good plan If that is what they want, OK. We can follow direction. ASC and SAFE=20=C2=AE have already filed over 24 exemption requests in support of manufacturers and individuals. But, there is an easier answer. ASC has filed two =E2=80=9Ccommunity exemption requests=E2=80=9D that will be administered by ASC for =E2=80=9Cfree=E2=80=9D. One will allow manufacturers and owners to certify Special Light-Sport Aircraft (SLSA) and Operating Fleet Experimental Light-Sport Aircraft (ELSA) which are amphibious. The other will allow Amateur Built Experimental Aircraft (AB) which are amphibians to be used by pilots operating under the limitations of Sport Pilot privileges. You can help. Please comment in support of the exemption requests. It is=20 easy. Just got to _http://dms.dot.gov_ (http://dms.dot.gov/) . First download and read the lead docket letters. Then go back and submit a supporting comment to the dockets: Community SLSA/ELSA with retracts Docket 24241 Community AB amphibians a LSA Docket 24468 Other individual dockets 24129, 24434-36, 24469-82 The community needs your help. The FAA needs to move on these =E2=80=9Cbridge=E2=80=9D exemptions quickly. Tell them that. Write and help.

They are complete with new rings, piston pins and keepers. I had the crowns ceramic coated by Swain industries and the skirts coated with anti-friction material. These are top of the line and ready to install. Let me know off list if interested. Once these items go on EBay the world will be looking. Few other items going as well: (more later) Yaesu VXA-200 with programming software and cable, extra NMhi battery, has pressure sensor and density altitude display, 5 watts, 150 ch memory, VOR NAV, NOAA weather, temperature, doesn't get any better. CO guardian carbon monoxide detector, plugs in to lighter socket, visual and audible alert. Two E.I. digital EGT gages CAP 140 electric adjustable prop hub, needs new blades, comes with reusable hubs to be put on new blades.
