The suggestions regarding recovery from Paul Mulwitz, Tony Graziano and Bob Archibald were excellent. Although I have not heard from the person who experienced the flutter or large amplitude vibrations here in Lantana last week, I do have some thoughts regarding this problem. It appears there may be many factors involved when this problem hits. Here are a few items to keep in mind if you want to avoid this potential problem. 1. Always stay within the aircraft's specified CG envelope. 2. Always do a thorough pre-flight to discover any loose or wobbly control surfaces. This can sometimes induce flutter in the control surfaces and sometimes cause a harmonic vibrational instability to the wing or loss of the control surface itself. 3. Visually inspect the wing surface and note any indications of "smoking rivets." .This is a condition involving loose rivets that vibrate in position leaving a black ring around them or a small trail of residue in their wake. The main reason for concern here is that the torsional strength of the structure may be compromised should enough of these rivets start to fail. And if torsional strength is lost, a flutter of the wing is a good possibility during some conditions. Flutter would be exhibited through severe up and down motions of the trailing edge of the wing in which normal damping of the wing structure would be absent. 4. If you are startled out of your mind when a severe oscillation of the wing occurs (either from flutter or some form of harminic vibration in which the tip of the wing starts to gain and lose amplitude), do not make rapid changes in control surfaces. The explanation by Bob Archibald is an excellent exmple of what procedures may be done to stop the flutter, both in slowing down and speeding up 5. Don't assume that because people say this is a non-issue and that the wing of the 601 is very stiff that, under the right conditions, you wouldn't also have your family reading about "pilot error" in the newspaper. If others have some input, please let us know. In the meantime, I'm going flying as soon as possible in my newly registered 601XL, N601EL.

You could also make a single ply glass/epoxy 3:1 teardrop fairing that would overlap and tape in place so that it could be easily removed for periodic inspection.

Excellent choice. You'll find the engine is well built, will deliver great mileage consuming low 3.5 to 4.0 gph and deliver well over 100 hp. Water cooling is going to make the plane quieter than any of the air cooled variety. Parts are very reasonable and accessible. You won't have to look for ancient parts or pay gold plated prices for repairs either. I've been flying a Stratus Subaru for 3 years now and it's a great engine. Burns 100LL or 87-octane car gas and likes it. If you need more information on making the Subaru a reliable conversion, my website covers just about all you need to see in cooling, ignition and fuel systems. Ram's Subaru conversion is a great engine and Stratus also has been a good conversion for a lot of people. If you wish to have more information, just send me an email and I'll provide you with additional specifics as needed.

The Subaru is easier to start, and Bing carburetors are altitude compensating to provide the correct mixture as you climb. Temperature changes are not a worry because the engine operates at a CHT of around 220, oil is 230 and water is 180 to 205. EGTs are kept to 1350 to 1425. There is no shock cooling as found in a air cooled engine. The Subaru will outlast an air cooled engine because it's built more robust at the crank and bearings. When disassembling a Subaru after 250K miles, you'll often see the spiral grooving in the cylinders is still very pronounced and able to hold onto oil. An overhaul on my Stratus will cost approximately $600.00 in parts. All else considered, I think the Subaru has more going for it than any of the conventional engines. Just my .02 cents.

Twas the night before Christmas 'Twas the night before Christmas, and out on the ramp, Not an airplane was stirring, not even a Champ. The aircraft were fastened to tiedowns with care, In hopes that come morning, they all would be there. The fuel trucks were nestled, all snug in their spots, With gusts from two-forty at 39 knots. I slumped at the fuel desk, now finally caught up, And settled down comfortably, resting my butt. When the radio lit up with noise and with chatter, I turned up the scanner to see what was the matter. A voice clearly heard over static and snow, Called for clearance to land at the airport below. He barked his transmission so lively and quick, I'd have sworn that the call sign he used was "St. Nick". I ran to the panel to turn up the lights, The better to welcome this magical flight. He called his position, no room for denial, "St. Nicholas One, turnin' left onto final." And what to my wondering eyes should appear, But a Zenith-built sleigh, with eight Rotax Reindeer! With vectors to final, down the glideslope he came, As he passed all fixes, he called them by name: "Now Ringo! Now Tolga! Now Trini and Bacun! On Comet! On Cupid!" What pills was he takin'? While controllers were sittin', and scratchin' their head, They phoned to my office, and I heard it with dread, The message they left was both urgent and dour: "When Santa pulls in, have him please call the tower." He landed like silk, with the sled runners sparking, Then I heard "Left at Charlie," and "Taxi to parking." He slowed to a taxi, turned off of three-oh And stopped on the ramp with a "Ho, ho-ho-ho. " He stepped out of the sleigh, but before he could talk, I ran out to meet him with my best set of chocks. His red helmet and goggles were covered with frost And his beard was all blackened from Reindeer exhaust. His breath smelled like peppermint, gone slightly stale, And he puffed on a pipe, but he didn't inhale. His cheeks were all rosy and jiggled like jelly, His boots were as black as a cropduster's belly. He was chubby and plump, in his suit of bright red, And he asked me to "fill it, with hundred low-lead." He came dashing in from the snow-covered pump, I knew he was anxious for drainin' the sump. I spoke not a word, but went straight to my work, And I filled up the sleigh, but I spilled like a jerk. He came out of the restroom, and sighed in relief, Then he picked up a phone for a Flight Service brief. And I thought as he silently scribed in his log, These reindeer could land in an eighth-mile fog. He completed his pre-flight, from the front to the rear, Then he put on his headset, and I heard him yell, "Clear!" And laying a finger on his push-to-talk, He called up the tower for clearance and squawk. "Take taxiway Charlie, the southbound direction, Turn right three-two-zero at pilot's discretion" He sped down the runway, the best of the best, "Your traffic's a Grumman, inbound from the west." Then I heard him proclaim, as he climbed thru the night, "Merry Christmas to all! I have traffic in sight." -------- W.R.

They e-mailed me the installation sheets on how it's done. Not being smart enough to figure how to send the sheets, let me give you a verbal rundown: The chute and its rocket go into th e rear area of the baggage shelf, with four main straps that go outsid e the fuselage. The two front straps go along the fuselage, through a hole just about forward of the rudder pedal, where they attach to a ri ng. That ring goes to a short strap that goes to a hefty cross-bar on the forward side of the firewall. The rear straps go back into the fus alage through a round hole, to similar rings, which in turn are strapp ed to hefty bars under the fuselage bottom skin. After deployment, the four straps hold the fuse in a level attitude. The setup, althou gh not particularly esthetic, is simple and strong. My plan is to add another bulkhead to separate the rocket from the baggage compartment, and to add .016 "false skins" riveted at approximately the wing root, and held at sides and top with a single bead of silicone sealer, to co ver the straps. I figure the straps will tear away the silicone and de ploy vertically.

The Subaru is easier to start, and Bing carburetors are altitude compensating to provide the correct mixture as you climb. Temperature changes are not a worry because the engine operates at a CHT of around 220, oil is 230 and water is 180 to 205. EGTs are kept to 1350 to 1425. There is no shock cooling as found in a air cooled engine. The Subaru will outlast an air cooled engine because it's built more robust at the crank and bearings. When disassembling a Subaru after 250K miles, you'll often see the spiral grooving in the cylinders is still very pronounced and able to hold onto oil. An overhaul on my Stratus will cost approximately $600.00 in parts. All else considered, I think the Subaru has more going for it than any of the conventional engines. Just my .02 cents.

I fly a 701 with streamlined struts. The struts are made of extruded, anodized, 6061-T6. I do not think extruded struts offer any considerable aerodynamic performance advantage over the steel tubes with fairings, but . . . these struts are really very nice aesthetically (especially when up close). I am currently building an 801 and I am installing similar extruded aluminum struts on it as well. NOTE: The 801 will obviously need bigger, beefier, stronger struts than a 701. Changing over to the, more refined, extruded aluminum strut is not a simple undertaking. Here are just a few considerations: First and foremost is SAFETY, you must ensure that the strut material and extrusion design is approved by an engineer so they are structurally adequate. My advice here is to contact Mark Townsend at Can-Zac Aviation Ltd. Can-Zac has recently done some development in this area. Once you have extruded struts that you know are adequate from a safety standpoint, the biggest challenge is to engineer and then create the attachment pieces that will anchor both ends of the struts to the underside of the wing and to the fuselage respectively. To solve this problem, you will most likely need the help of a talented machinist who is willing to do some creative work. One of the machining challenges here is to establish (and then cut) the proper angles for the mounting-slot in the attachment pieces. You will find some difficult compound angles and depending on accuracy of the airplane's construction, the angles may differ side to side. Next there is the issue of the jury-struts. All of the same design/engineering/machining considerations, noted above, also apply to the jury-struts. Remember that you will need a compression block inside the hollow extruded main strut so an attachment eye-bolt for the jury-struts can be tightened without compressing and deforming the walls of the main struts. I estimate that this one refinement added at least a month to the build time and several thousand dollars to the cost of my 701 and a bit more to my 801. You can see the struts on my CH701 on my website: www.STOL-Adventures.com I have just produced a DVD of my backcountry flying adventures featuring my 701. There are some close-up shots of the streamlined 701 struts in the video. I hope these comments are helpful.

This is what I would do: First recognizing flutter. The most likely indication will be buzz or strange vibration in the control stick/wheel or rudder pedals. At first indication reduce power (idle if altitude and speed permits) and simultaneously pull up to reduce speed. This will: 1- less speed should reduce the destructive forces caused by the flutter, and ; 2-increased "G" from the pull up will change the pressure pattern over the offending control surface (s). Either one or both of these changes should cause the flutter to stop. Avoid return to the same flight conditions that existed when flutter occurred and land asap to check for damage and the cause. Any change in speed, loading, control input, configuration, etc. may break the flutter. Because flutter causes more drag., trying to increase speed may prolong flight in flutter mode (not a desirable outcome). Higher speed also equate to higher aerodynamic loads and early control failure. I would not increased speed. Flutter can be caused by too much elasticity in the wing or stabilizer surfaces. When they bend (Twist) they transfer forces to the attached control surface which bends and moves in the opposite direction thereby amplifying the oscillation on the wing. This can lead to rapid wing or stab failure. Loose bushing in control hinges, too much play in control rods/cables can also induce flutter. Balancing the control surfaces can help prevent flutter and minimize the effect if it does occur. Testing for flutter is not for the faint of heart. That is why test pilots make big money and wear parachutes. They fly the envelop and tease the control by bumping the stick to try and induce flutter. Fortunately computer simulation can predict most flutter modes.... but not all. Mack I hope this info helps you or someone else avoid flutter. Clearly, flutter is not common and we are fortunate that most of the a/c we fly have been tested by the designer and proven by the many who have built and flown them before us.

The standard trailer tires received for my HDS are 16 inches in diameter. Now with many, many landings on them the tread is wearing thin and I got the Michelin S 83 tires that Bill Morelli suggested using many years ago. I asked Larry Mac for the diameter of his and he said 15 inches. I bought some for replacement and can affirm the 15 inch diameter with the bonus of a much smarter look. Sketching up cross sections for new pants to go along.

This could be considerably lighter than the Carlson strut extrusion depending on size. Length is also not limited like the Carlson parts. Also the drawn tube does not have the "pad" on the inside making flat an parallel mounting interface - you will have to create something to affect the same result. A Merry and Blessed Christmas to all! Cut and paste from my email (Kevin) for Christopher Desmond I am a occasional list reader and I saw your question about using streamlined struts (I haven't yet figured out how to post, so if you wish, you can cut and paste this to the list, it is a good question and I haven't seen these issues discussed previously). I fly a 701 with streamlined struts. The struts are made of extruded, anodized, 6061-T6. I do not think extruded struts offer any considerable aerodynamic performance advantage over the steel tubes with fairings, but . . . these struts are really very nice aesthetically (especially when up close). I am currently building an 801 and I am installing similar extruded aluminum struts on it as well. NOTE: The 801 will obviously need bigger, beefier, stronger struts than a 701. Changing over to the, more refined, extruded aluminum strut is not a simple undertaking. Here are just a few considerations: First and foremost is SAFETY, you must ensure that the strut material and extrusion design is approved by an engineer so they are structurally adequate. My advice here is to contact Mark Townsend at Can-Zac Aviation Ltd. Can-Zac has recently done some development in this area. Once you have extruded struts that you know are adequate from a safety standpoint, the biggest challenge is to engineer and then create the attachment pieces that will anchor both ends of the struts to the underside of the wing and to the fuselage respectively. To solve this problem, you will most likely need the help of a talented machinist who is willing to do some creative work. One of the machining challenges here is to establish (and then cut) the proper angles for the mounting-slot in the attachment pieces. You will find some difficult compound angles and depending on accuracy of the airplane's construction, the angles may differ side to side. Next there is the issue of the jury-struts. All of the same design/engineering/machining considerations, noted above, also apply to the jury-struts. Remember that you will need a compression block inside the hollow extruded main strut so an attachment eye-bolt for the jury-struts can be tightened without compressing and deforming the walls of the main struts. I estimate that this one refinement added at least a month to the build time and several thousand dollars to the cost of my 701 and a bit more to my 801. You can see the struts on my CH701 on my website: www.STOL-Adventures.com I have just produced a DVD of my backcountry flying adventures featuring my 701. There are some close-up shots of the streamlined 701 struts in the video. I hope these comments are helpful.
