PIE 4.8 Swing Test #1

I had previously said I did not believe the swing test to be accurate, but there have been a lot of people asking for it. So I decided to go ahead and demonstrate how it passes this swinging test. I am also showing how and why it can fail the test.
Since I am not out to “prove” anything, just demonstrate the machinery I am working on (and with) this actually seemed like a good idea.
Here is the main point I want to make. ANY pulsating drive (mine or any other) will not show good results unless it is synchronized to the time-base set by the swing itself. The longer the swing, the slower the machine has to run otherwise it is just a vibrating mess!
This test had the PIE running VERY sow so that there was only about .5 KG of thrust, but it is a good demonstration of linear thrust either way.
Thanks for watching!
