Goguen" > Hey guys, After reading, on this list, about some rudder petals cracking at the weld joint, I thought I would strengthen mine without removing them from the plane. To remove them I would have had to drill out all the rivets that secures the firewall to the bottom of the fuselarge. Then remove the lock nuts that hold the rudder petal mounting brackets. I would have to get reinforcements welded, repaint or powder coate and reinstall. Anyway, I made a pattern (my original trade "pattern maker") and had aluminum castings made. They look like a split pipe tee with the bottom partially removed to clear the floor boards. Two small cap screws will hold them in place while the structual adhesive cures. The vertical arms are then riveted.

We use a key switch to acting like a master switch only. This simply connects/disconnects power to the power buss bar. You could also use a good quality toggle switch for this. 2. We use 2 "single throw-double pole-momentary switches for the mags (one switch for each circuit). These switches are "down" for closed (kills the ignition) center is open (run) and momentary up also kills the engine but this position of for mag checks only... This makes sure that the engine returns to a "run" condition after doing a mag check... There is no chance of accidentally leav ing either mag in a closed situation while running the engine. The switch we use is manufactured by Cole-Hersee (part no. 55088) and can be purchased at any NAPA store. We run each of the grounding cables (P-leads) up to the switch. These go the bottom terminals on the switches. We also run a separate ground from the engine up to the switch. We use RG-74AU coax for this purpose. We use the shielding as the ground wire. The grounds attach to the center terminals on the switches. We run a jumper from the center terminal to the top terminal so the ignition will ground out when the switch is placed into the monetary on mode.

It is interesting. When I went to Alaska to fly helicopters for Alaskan Helicopters in 1967 I just went up there and started flying without any particular briefing other than how to land on water with floats which I had never done before. I guess flying helicopters is different but at that time I thought I could go anywhere in the world and do my thing and not think anything much about it. One thing about a helicopter you can land almost anywhere at anytime. A Kitfox comes pretty close to that. At that time the only unusual legality they had about flying in Alaska was you couldn't shoot any animals out of a helicopter. If you did it could be confiscated. The fixed wing boys could still hunt wolves from an airplane which they did in the winter using skis so they could land and pick up the dead wolves or whichever part of their anatomy they had to turn in as proof of the kill. I don't recall what that was. I think they skinned them as well since the pelt was valuable as well. A dead wolf was worth a $50 bounty then - a substantial amount of money in 1967. Thanks for keeping me updated. Maybe next year....

I will continue to send notes of interest only to those who are thinking about going on the trip, so let me know real soon if you are interested. We now have four or five confirmed pilots20and looking for more. This note is the second in a series about our Kitfox trip to Alaska in June 2005. The emphasis of this note is to get you started on gaining information about the trip -flying conditions, what to expect, and how to go about planning for the trip. This information may interest you, whether you plan on making the trip this year or at another time. One of the best resources is the E2809CLogbookE2809D published by the Alaska AirmenE28099s Association. I recently received my copy in the mail and havenE28099t been able to put it down, even though I know quite a bit about the subject. You can either buy the book from the Alaska AirmenE28099s association for $35 or the best deal is to join the Alaska AirmenE28099s Association for $35. As a member they will send you a copy of the Logbook free, plus a yearE28099s membership, which includes a bi-monthly newsletter and a packet of miscellaneous information. Part of this packet is information about flying20in Canada, including customs information for entering Canada and returning to the United States. (I will prepare an information note about customs and Canadian flying later.) The Logbook is intended to provide information for general aviation pilots about flying to and in Alaska. It provides a way to gather a cross-section of information into an easily accessible and understandable format. Sections of the Logbook include weather, terrain, legalities of flying in Alaska, being prepared for the flight, contacts with the Alaskan wildlife,survival, other reference materials, flying in Canada, descriptions of the various routes to and within Alaska including airport diagrams, and side trips.

I can lock the mags (and thus the engine) off. I didn't put the starter solenoid on the keyed switch though. I added a starter button. Thus I can crank the engine, to use Clint's 912 starting procedure, without the engine starting because the key is off. I turn on the mags to start the engine. And I can check the individual mags just like a Cessna. ;-) I would probably have used the setup Bob describes if I didn't already have the keyed switch.

An outside antenna with ground plane. And the handheld was powered fromthe plane's cigarette lighter at the time. As a last resort, I pulled the cigarette lighter plug and let the handheld run on its own batteries. No difference - it still picked up a lot of noise from somewhere. I gather than squelches work by measuring the signal strength on the frequency dialled in. When the signal strength gets to a certain level, the squelch opens and sends everything it hears, through to the amplifier. Hopefully this happens only when someone nearby is transmitting something you want to hear. If you turn the squelch knob, the signal-strength level that opens the squelch, increases. As I said originally, I wish I could turn the knob a little farther on the handheld. Evidently the maximum signal strength the handheld's squelch can be set to, is somewhat lower than the maximum signal strength the KX-170B's squelch is set to. I really think it's a simple as that. Didin't mean to generate a lot of controversy here.

Didin't mean to generate a lot of > controversy here. Well, I don't think there is any controversy here, Steve. In my understanding of the English language, a controversy is only present when two opposite ideas are being discussed. I would rather call your problem an enigma because I just can't figure out what it is. Let me recap: You have tested two handheld radios that both - in your understanding - should have the squelch control able to go higher. This can exclude an internal component failure in one radio since both behave the same way. But radios are built in such a way that proper squelch adjusting is never more than maybe a fifth of the total possible setting. The squelch function works as you said, a threshold that cuts low amplitude signals on the selected frequency. I am not sure but I think one could use a Smith trigger, that is a transistor that leads, or not, depending of the voltage fed to its base. But since you have two handheld radios, what you could do it this: Set one with the squelch to the lowest. Use the other to send, nearby, a signal by simply pressing the key but don't modulate it with voice. That should cut out the noise on the other radio because now, instead of picking stray noise from the atmosphere, you get a good modulated signal with ... nothing on it. Actually, I am not 100% sure because aviation VHF is amplitude modulate, while maritime VHF is frequency modulated. But I know that with the latter, I can e.g. listen to a good, strong signal from say, a coast station, screw the squelch all the way down, and still not hear any noise at all.

No room to turn the long mounting screws with a tool. I had to saw off the back end mounting bracket casting of the new starter to clear some hoses I had installed for the cabin heater. That part of the starter housing is not used when mounting it on the 912 series engines. I don't think I had a clearance problem with the firewall or engine mount with the Series 6 installation. I would recommend that you saw off the rear mounting bracket of the HD starter anyway to make more room available for other things and reduce a little weight. It serves no purpose on a 912 and why not lose a few ounces everywhere you can. Lockwood says it won't create any problems and that's what they do. -- John King Warrenton, VA Mdkitfox@aol.com wrote: >--> Kitfox-List message posted by: Mdkitfox@aol.com > >John, > >Did you have to rework the firewall or engine mount due to the HD starter? >I've installed both the slipper clutch and HD starter, but have not mounted >the engine yet.
