    Do you know if...

    I don't think they do....at least not without wheel pants. I don't think the ones with fairings do either. Even with the pants on I can feel them shake after take off but a quick tap on the brakes makes it stop. If they were turning they'd be shaking.....maybe? Frank (in a 175 Cessna)

    Welding Aluminum

    Most aluminum can be welded but some require special preparation to do so. 7075 is a tough one because the zinc in the alloy causes issues. 2024 has some problems along those lines as well but can still be welded. Chances are that your carb air box isn't one of the special alloys and is readily...

    Tell me about gyrocopters!

    That runway looks familiar.....where is that? Frank

    1000 yards w/ 9mm

    I understand and know that they were made up til the 60s and possibly beyond but the design is from the late 1880s. It is about the only revolver which is reasonable to suppress because the cartridge case is longer than necessary to hold the bullet and acts as a seal between the barrel and...

    1000 yards w/ 9mm

    As someone who make suppressors for a living I can tell that you know little or nothing about this whole subject. Suppressing revolvers is a waste of time and its only done in the movies and on special russian pre WWI revolvers that use a gas seal for the cylinder. Gas leakage between the...

    1000 yards w/ 9mm

    Not sure if this will show up right or not but according to the ballistic calculator I use frequently the velocity at 1000yds will be about 510 feet per second. Thats using a starting velocity of 1250 fps which is about normal for 9mm. Not sure what shooting in a revolver does to velocity but it...

    Any Commander 112/114 pilots in the house?

    I have some time in a 114 and an hour or two in a 112TC and really liked both of them. Roomy isn't really an adequate term to describe the cabin. Its really comfy. I don't recall a huge number of switches either...nor circuit breakers so not sure what your mechanic is talking about. As others...

    Why cadmium plated bolts rather than stainless steel?

    That would be called "galvanized" coating and while it may be fine in real life I'm sure the snobbie types would cringe at the thought. I'm sure it would work well as we use zinc blocks for sacrificial anodes on aluminum boat parts to prevent them turning into AlO2. On the other hand we're...

    LongEZ VS RV7?

    From many years experience with composites and a little bit of experience in the long ez I don't think there is any comparison between the RV and the ez. The ez uses a whole lot more runway, its not as maneuverable, 2 guys and a lunchbag is more realistic than a backpack, speeds aren't much...

    F1 vs NASCAR

    After 15 years on the road with an Indy car team I really hate circle tracks. More damage is done when they crash and most of the races are really boring. Indy 500 tops the list of boring races. Trying to stay awake in the pits is not easy. Elkhart Lake is a 4 mile road course and its a tough...

    High altitude balloons

    I used to see balloons up all the time....could usually see them around sunset when the ground level was dark and the sun would light them up. Sandia Labs, Los Alamos and the military do a lot of high altitude stuff with balloons in New Mexico. Sometimes they even alert air traffic. I think if...

    N/A PIREP request: Roswell, NM

    Hanger 18 is in Roswell....still there in the late 90's at least. As noted Area 51 is not. Deming and Roswell are way different both in terrain and people. I'd not live in Deming either though I did live in Las Cruces for a while. Frank

    N/A PIREP request: Roswell, NM

    I used to live and work in Roswell....graduated from the Military School there way back as well. I took my first airplane to Roswell after getting my license in San Jose kommiefornia. Roswell industrial air center has a 13000ft runway and a 8 or 10000 footer as well. Lots of other runways around...

    Driving sucks...

    Just finished a trip from Indiana to Phoenix and back via box truck. About 35hours of driving each way and my favorite part is from the Texas - New Mexico border to phoenix and back. We made a few stops for proper mexican (new mexican) food while crossing the state and really enjoyed it...

    Jetta TDI

    I've been driving my 2006 Jetta TDi for quite some time now. Its got 159,000 on the clock and repairs have been timing belts and a clutch. Mine is a 5 speed. Oil changes are done every 5k miles. Mileage on the highway averages over 45mpg and hotrodding around the home area I can get it down to...

    4 Bolts

    I think you all need to look up some hard to find info on actual AN bolts. Standard AN bolts are 125,000psi and the high strength stuff goes up much higher. Here is a link to a chart. Of course there are safety factors involved but that doesn't involve derating bolts to grade 5 standards...

    Daily Pic

    Some of these pics need to be bigger as I can actually make out an entire rivet in some of them. Maybe resize before posting so that those of us in the boonies and see too. Frank

    2013 Jetta TDI

    Thats too bad.....both of mine (2006 sedan and 2009 wagon) have had no issues I didn't cause and the biggest problem I have with them is finding diesel in some places out east. 160K on the 06 and 110K on the 09 and its only 2 fill ups away from the the folks or the inlaws 1300 miles in either...

    Aluminum trucks coming. Big industry bet - what will consumers say?

    My 61 MGA and 63 Landrover had aluminum body panels. They've been doing it for a very long time. Aluminum has been used in big over the road trucks for even longer. Weight that you aren't carrying as part of the transporter is weight you can carry in the the transporter. All you need to do is...

    Engine temp did not rise?

    Frequently you will get no indication at all on the temp guage for the oil until you're in the air and climbing. The oil isn't like a cylinder head which warms up quick when running. As others noted adding more oil only increases the amount which must be heated in order to get a reading. Most of...
