The font size is too **** small. I’m not 25 and haven’t been for a very long time.

If British, they used valves, not tubes. The number of zeppelins was limited by the number of cows available for slaughter. The gas bags were made from cow intestines.

750 Volts at 550 Amps, I doubt they can do that for 200 miles.

Having flown in the “aluminum overcast” a couple of years ago, I’d recommend that to get a B-17 fix.

Building an RV-4 fuselage from the kit is pretty close to scratchbuilding. Nothing fits without lots of modification if you want smooth skins.

I didn’t specify, but was driving a socket from the breakover bar. When considering torque, a formula containing a force and distance is implied. More important is how that torque is applied and condition of the fastening hardware it is used on. Further, there is a rather large range of...

Consider tying the tail down to limit rotation and chocking the tires to examine horizontal tail authority when under full power.

I couldn’t find one locally at the time, so I used a 6” long 1/4” break over handle and a small fish scale that I calibrated. Made a little loop from a bread tie and pulled with the scale perpendicular to the handle.

I don’t think static tests of a prop mean very much, as much of the prop is stalled. You measured 11 degrees at the tip, but using what reference? Th backside of the blade or the actual zero lift point of the airfoil, or the center line of the airfoil. Of course, I disagree with adjustable...

I get these request every month or two. They are looking for tracks of land roughly 1/2 mile square next to higher voltage line.

I read a couple weeks ago that the solar panel roads were spectacular failures.

2 grams of CO2 mixed with the 960kg of air above each square foot (sea level). Plants thank you.

The amount of oil consumed each year is incredibly insignificant, just a touch over one cubic mile. In the past 140 years less than 50 cubic miles has been consumed overall. This from a planet with a surface area of 196.9 million square miles. Spread evenly over the entire surface each year...

One should learn how to fly on the backside of the curve. Very useful for controlling glide distance. But you do have to relax the excessive elevator to get back enough flying speed to flair. The problem for many is they can be unaware that they are on the backside. When they attempt to...

Last time I horsed around with a 150 I pulled the throttle back to low and also pulled the yoke as far back as it would go to see how it mushed. The airspeed reads around 40 and you bob slightly but nothing much untoward happens other than altitude lost. Saving the plane is not the goal...
