Builders,
Today I received a number of questions asking for a bit of clarification on last nights Pietenpol story. In that story I tried to explain some of the planes issues.
.
If you are real new to aviation, a ‘Parasol’ is an airplane configured to look like a biplane without lower wings. Just after WWI, this was the configuration of choice for front line combat fighters. It persisted into the 1920s, and they were the bridge between biplanes and cabin monoplanes. The most famous one today is the 90 year old Pietenpol Aircamper, but over the years, there have been a number of classic homebuilts with this configuration, and some factory built beauties like the Fairchild 22.
.
In the interest of sharing some info which all Piet builders should understand, , I made a quick video using a ugly balsa representation of a parasol. The esthetics shouldn’t deter anyone from understanding the concepts.

Note, I was tired when I shot this, I did it in one take, and without any kind of a script. I just had a phone call where I was explaining the difference between compression and column bending to a builder who was asking about jury struts. Twice in the video I mistakenly say column bending instead of compressive load. Just ignore it, thanks.
