Is there a quick way to calculate what the hinge moment (or turning moment for the flap shaft for a specified condition) is for a flap on a symetrical foil

Björn Flodén and his wife built one of the first BD-4s back in the 70s. When they moved to Colorado he wanted more power and installed a Ford V-8. He never got it in the air, though, as he passed away before completion. His daughter wants to sell his project now. While the BD-4 builders help...

I have always suspected that correctness, is the refuse of those who have nothing to offer.

For those who built their airplanes for greater efficiency: At this year's Copperstate Southwest Regional Fly-in, we will be hosting another fuel efficiency contest. New for this year is an additional 200 mile competition for aircraft flying the course at 60 to 119 miles an hour average...

I just read in the newspaper that John Walton, the billionaire son of Wal-Mart founder Sam Walton, was killed in a homebuilt airplane? That got me thinking to look for a NG that might be dedicated to this activity, and I found this one. This is all new to me, quite honestly, and disturbing. ...

I'm sure everyone here is familiar with the combination of the horizontal stabilizer and elevator to make a stabilator. I think I have even heard of the concept being used for a ruder. My question is has anyone ever made a plane taking the concept all the way and made a "wingeron"? My guess...

Hi, Here is a new design challenge for those of you with homebuilts with all the bells and whistles. The 2004 Toyota Prius hybrid car has a Denso electrically powered air conditioning compressor that apparently does not need to be mounted on the engine. This offers the possibility of reasonably...

whilst taking a break from my main project (http://www.dlc.fi/~jmpaaso/experimental/), I stumbled upon the concept of Bell xp-77. Being all wooden, it appealed to me and now I would like to hear anything and everything concerning this aircraft. Are there any existing drawings ? anywhere, anyone?...

I have got into plotting NACA profiles by computing. Humbly beginning with the simplest, which I presume to be NACA 4-digit, I found the Wikipedia page as a prime source of information. Plotting a symmetrical profile is not that hard: at regular intervals (=X along the chord), one calculates...

I'm looking for some guidance on safely mounting instruments in an alumimium panel. Our panel is about 2mm (about 1/12th inch) thick. We had all the shapes laser cut, so everything fits well. What do most of you do with deep, heavy instruments like a gyro? Is it safe to just use the screws on the...

Having to reject the last nicropress on the rudder, two strands were cut when the nircopress was cut off with a drmel tool. The question is whether we can reinstall a nicropress in the original position and then add one an 1/8" further?? or, Make splice two lengths of control cable with double...

Its not much flying time around here in SD with temps averaging 0F. I got my engine (Franklin 6) apart trying to cure a vibration problem (0.4 IPS) - not extreme but anoying. Is it OK to balance the crank in a automobile machine shop or are there some tricky things about aircraft cranks? I know...

I am unclear on two Sport Pilot issues: First, a new pilot may qualify for a Sport Pilot ticket even though he or she takes a medication that would preclude a 3rd class medical. However, an experienced pilot with a higher ticket may not operate as a Sport Pilot if he lost a medical last year for...

Okay, I don't know diddly; I've just caught the airplane bug. So, I'm asking... My buddy went out and spent multi tens of thousands of dollars on an airplane engine. Lycoming, I think it was. Seems kinda pricy, but I understand that most of that cost is testing, no iron. I note that there was a...
