    Subject: Who is "Matt Dralle" & What Are "The Lists"? [Please Read]
    Dear Listers, Who is Matt Dralle and what exactly are these Lists? Well, I've been working in the information technology industry for over 20 years primarily in computer networking design and implementation. I have also done extensive work in web development and CGI design during this period. I started the Matronics Email Lists back in 1990 with about 30 fellow RV builders from around the world. Since that time, I have added 63 other kinds of aircraft related Lists to the line up and numerous other List related services such as the Forums, Wiki, Archives and Search Engine just to name a few. For flexibility and reliability, I have chosen to run all of my own servers here locally. Other List-related systems include a 1 Gigabit, fully switched network infrastructure, a commercial-grade Netscreen firewall, a Barracuda spam filter, a local T1 Internet router, and a commercial-grade business T1 Internet connection with full static addressing. The computer servers found here include a brand new, quad-processor Xeon Linux server for List web services, a dual-processor Xeon Linux system dedicated to the email processing List functions, and another P4 Linux system serving as a remote storage disk farm for the archives, databases, and for an on-line hard drive-based backup system with 3.2 Terra Bytes of storage, soon to be upgraded to over 6 Terra Bytes! This entire system is protected by three large, commercial-grade uninterrupted power supply (UPS) systems that assure the Lists are available even during a local power outage! Speaking of power, imagine how much electricity it takes to run all of these systems. One month this Summer, I had a staggering $1368 bill for electricity alone! I recently upgraded all of the computer racking infrastructure including new power feeds and dedicated air conditioning for the room that serves as the Computer Center for the Matronics Email Lists. This year I added another rack to house the new MONSTER quad-processor web system that didn't quite fit into the first rack! Here's a composite photo of the List Computer Center before the addition of the second rack: http://www.matronics.com/MattDralle-ListComputerCenter.jpg As you can see, I take running these Lists very seriously and I am dedicated to providing an always-on, 24x7x365 experience for each and every Lister. But building and running this system isn't cheap. As I've stated before, I don't support any of these systems with commercial advertising on the Lists. It is supported 100% through List member Contributions! That means you... and you... and YOU! To that end, I hold a List Fund Raiser each November and ask that members make a small Contribution to support the continued operation and upgrade of this ever-expanding system. Its solely YOUR Contributions that keeps it running! Please make a Contribution today to support these Lists! http://www.matronics.com/contribution Or, by dropping a personal check in the mail to: Matronics / Matt Dralle PO Box 347 Livermore CA 94551-0347 USA (Please include your email address on the check!) Thank you! Matt Dralle Matronics Email List Administrator

    Subject: Re: Shinden33 Rough Running[LashBack]
    You did not say you tried isolating the problem to one mag or the other? Have you looked inside the magnetos under the mag caps and checked for adequate lubrication on the cam? Also look for obvious binding at the points. Verify the point gap is between .25 mm and .35 mm or .010 to .14. Ideally, .3 mm or .012. Look inside the mag cap for carbon tracks. Gary's suggestion is also very sound and highly recommended. Check the timing on both mags. Let me know what you did or found.

    Dennis, We've done all tests/run-ups on both mags and each mag separately with identical results. I did pull the cap on the left mag and checked everything that you mentioned below and checked out good. It would have to be spectacular luck (good or bad your choice of words) to have identical ignition failures on both mags at the same time or to have the time go out the same amount. Unless of course, there is some form of crossover I am not aware of. Thanks for the advice though.

    I had similar experiences with both the Huosai and M14 P engines, Turned out to be breakdown of the mag coils ( the condenser is built into the coil ) so that part can break down but the mag still produces a spark, but erratic. Cured by changing the mag coils. Joe

    I would like to clean my fuel vent system on my CJ. What is the best procedure? Also, does anyone have M14P intake tubes they would part with. I am hoping there is a derelict M14 sitting around with tubes( hopefully the bottom tubes with drains) I can experiment with. Thanks Phil Salter

    There is a possibility the one way check valve at the T connection below the front seat might be the problem. Put about 8 oz of MMO (Marvel Mystery Oil) in both tanks per 15 gallons and do this religiously for the near future and see if it changes the fuel feeding from the left tank. The left tank on most Yak 52's feeds first, then the right tank starts feeding, according to the fuel instrument. My personal airplane feeds down to about 45 liters (sometimes 40 liters) on the left tank before the right one comes off of 60 liters. Been that way for 7 years now and the airplane fly's perfectly straight with no yawing, hands off.

    Phil, if I remember correctly, your lower 3 intake tubes have a small plug in them. I've installed the Kimball intake drain kit on these type of intake tubes many times. You just order the kit from Kimball without the large SS intake plugs that go on the larger intake tube drains on an M14. Use the #4 blue anodized fittings that come in the kit; remove the plugs and drill and tap the tube with a 1/8 NPT thread tap. Then screw the #4 fittings into them. If you press the drill bit and tap into a toilet ring wax seal (about $2 at the hardware store) before you start drilling and tapping, the wax will grab the metal shavings.

    Subject: Re: Hmmmmmmmmm That ain't right.
    Well I found out what the problem was. The QS-1 valve was the culprit. It was full of rust and corruption. I started the search by pressurizing the system with nitrogen to replenish the system tank since it was to low for a start. In doing so I could hear air escaping from somewhere in the belly. I traced it to the QS-1. I replaced it with one I already had on the shelf. Bingo problem solved. Test flight with some acro thrown in, showed all back to "normal". I can replace the rubber seal in the valve and the steel springs inside and she'll be put on the parts shelf, well oiled and greased in a baggy. Before this week-end I want to put her up on jacks. Retract the landing gear, than turn off the main air valve. I'll than note the time and gage pressure it takes before the gear starts to fall. Somewhere I remember reading that the minimum pressure for gear operation was 25 atmospheres and minimum pressure for brakes was 10 atmospheres. How quickly the pressure comes down will depend on seal wear and condition but it'll give me some idea anyway. It's kind-a nice going into the holidays knowing I don't have to change a compressor (knock on wood). ;-) Tomorrow I plan to take her on a short trip to New Smyrna to check on the B-24. Maybe take a look at those parts you never get to see unless the mechanics have the lady (Witchcraft) all apart working on her. Of course I'll have to take their beefs about how us pilots always break things. God help me! I do love it so. Jim (Pappy) Goolsby

    Subject: Re: Hmmmmmmmmm That ain't right.
    On the CJ6 the QS-1 is the brake pressure reducing valve... pull the brake handle and the cable feeds down under the front cockpit and pulls a lever attached to this valve... the air comes out of this and goes to the QS-2 differential braking valve. The position of the rudder pedals moves an arm on this valve which allows air to go to the left, both, or right brakes. Center the Pedals: air equally to both brakes. Full Left Pedal: air only to left brake, etc. I had a similar leak to Pappy's last month, but it was my QS-2, not my QS-1, that was going bad. My initial symptoms were loss of pressure during taxi and run-up... but ONLY if I had a lot of left pedal in... if I taxied/turned to the right I had no loss of pressure! Well, maybe a small loss.... afterall....we do kind of dance on the pedals on these birds, so any jab of left rudder would leak some air out. At first I didn't notice it because by the time you did a run-up the gauge would be back to 55 again...but after a time, the problem got progressively worse until I DID notice it! I isolated the problem by opening the main air valve prior to start and pulling the brake handle and moving the rudder to full left deflection... you could hear the air go into the brake circuit...but unlike the right side, which would give a whoosh then the satisfying little "squeal" followed by silence when the right brake/line was full of air, the left side would go whoosh and it would keep gushing air out of the valve as long as you had left rudder held in...if you held it in long enough, all air from the main system would be exhausted in this manner. You'd hear it under your seat, because that is where the sucker lives! If you centered the rudder amidship, or pushed right rudder, the nasty hissing sound would go away. I then opened up the access panel and with a helper, could feel the air coming out of the QS-2's front side. So I bought a new unit ( actually a QS-2B) from Doug, installed it and all is well.

    Subject: Re: Anyone know who this is?
    Turns in the vertical are one dimensional and turns in the horizontal involve two dimensional lift because you have to oppose gravity AND have a horizontal "lift" component, so the manuvers are quite different. The engineering term for cornering is P of S and it's a function of speed and g. For each aircraft there is ONE speed that will produce the smallest radius (with a given weight and density altitude), just like there is one speed that will produce the best rate of climb. ----- Original Message ----- From: "Roger Kemp" <viperdoc@mindspring.com> Sent: Monday, November 27, 2006 11:51 AM Subject: RE: Yak-List: Anyone know who this is? > > Any over the top maneuver is dangerous when you miss your altitude and/ or > airspeed at the top.
