http://www.youngeagles.org/photos/gallery/Monoplanes/LancairLegacy2000.jpg Look at the picture. It's easy to see why the Lancair is dangerous. The horizontal stabilizers appear to be on the too small side. This would result in their stalling before the wing. Then the aircraft would pitch up...

Apart from the Quickie group of planes why aren't there more fast biplanes? The quickies aren't exactly biplanes I know. It would appear that 2 short wings can be built lighter than one long one since the moment arm is half as long for the shorter wing pair. No struts used because of drag, just...

We used to mechanical instruments when we learnt fly in school. Whether it is habit we can not accept digital meters. For example quartz crystal watch, we almost accept it now. There few people using mechanical watch. I think it is developing direction for digital meters. I just wondered which...

Jim, you and your company were quite courteous on a prop bolt exchange, so I was gonna order some more mdse. And still hope to, even after this. This morning I tried to order a Concorde battery for a friend's 172, and the snappy lady in Griffin rejected the card, for curious reasons. After a...

Or a big propeller. Now that our conversion to an aviation theme-suites hotel is almost complete, we think it's time to make the *outside* of the place look more aviation-ish. (We've only changed the inside, thus far.) Anyone know where I can find an old Cessna 140 (for example) fuselage...

OK, we're still having our RF interference problem and our avionics guy pleads 'stumped'. Meanwhile we're going nuts whenever we need to get radar vectors for the ILS at our local Class D or when we depart IFR to the SE. Here is what we know 1) the problem is intermittant. occurs both at night...

I'm looking to start a home built aircraft. Does anyone have any suggestions on which type of lumber to use that's a good alternative for sitka spruce? Thanks

I found a set of plans on the net. I was wondering if anybody had a vp-2 that wasn't finished yet and would be willing to part with it fairly reasonable. I am currently implementing the plans into AutoCad/Solidworks. If you are interested in them for reference only...let me know. The plans for...

Well I just came across another piece of advertising masquerading as an article in Private Pilot magazine. The author goes up on a short hop in a Sting Sport, another plastic topy ariplane from the Czech Republic and he's raving about it like it's the biggest thing since sliced bread. He even...

Hi, So I was fantasizing the other day (as I do quite a bit) about my latest dream-plane-to-build: an RV-9A. (Note that this is fantasy in the extreme as I'm not a pilot yet AND I have no money!) I was thinking of how to power this plane. A Jet-A burning diesel would be great but that's another...

This round apparently goes to Zoom. Whether through guile, bluster, bluff ...or genuine journalistic stick-to-itiveness, Zoom was the we were not. He deserves an "atta boy." A question: What are his ANN numbers? Also: What do those numbers mean?

As a pet/learning project I made a data aquisition unit using an 8051 microprocessor and an EPIA M motherboard running a variant of Linux to process and display the information. It all works but the EMI from the EPIA M causes way too much noise to the aircraft radios. I have tried shielding the...

This is probably going to open old wounds. What I would like is experienced input on the advantages, for economic, efficiency and longevity etc. of different types of redrives. I am leaning towards a cog-belt reducer in a 6 cylinder, liquid cooled, configuration driving a long drive shaft to the...

I hope ADK, who posted a question a few days ago on an interesting design problem involving reduction gearing and a driveshaft got some insight from the various postings. The subject of torsional vibration quickly cam up and there was a lot of stuff mentioned, but not really a simple and...

This is a very lengthy but worth reading post. For the purposes of possibly saving someone's life or at least preventing serious injury to their wallets, I am posting below the text of an e-mail I sent recently to someone who had advertised a Cessna in the San Diego area. I was looking for a super...

I've had it with the El Cheapo Corp. tools I've been buying from vendors at OSH and other places. When I really need them to deliver, they break or fail to work as they should. I need a set of QUALITY safety wire pliers (like the great ones we used to use in the Marines in the late 70's and...

PLEASE FILL OUT THE FORM ...THANK YOU Attending OSHKOSH in 2007? ....YES Mode of transport? .....Rented Winnebago. Days? ..........Fri (evening) - Sun (morning) 10 days Lodging, or location on the field? .......Warbirds area

Necessity, as they say, is a mother. I am in the process of reinventing a square wheel called a vibration monitor. The electronics is relatively trivial IF the input and output parameters are known. What we know is that the engine is going to have a fundamental frequency at cruise RPM. Let's...

Global Flyer is on its historical around the world flight, but it is impossible to assess their site. What a shame! Jan

Yep. My wife and I decided that we want to build us an aeroplane. What we want is something that has 6 seats for the kids. It has to go 250 miles in an hour and only burn 6 gallons an hour. It has to be cool looking, have wheels that fold up, go through clouds and bad weather and be capbable of...
