Hi Clarence. The wall always 2 meter from the testing stand. The difference numbers is depend on your battery. Here is the video link for you to check with battery testing. th-cam.com/video/h0zbEELoqkw/w-d-xo.html
I don't know how to put the pictures at here. I send to your mail. The wall is 2 meter far from test stand. JP fan has high thrust is not base on that wall.
I see you use a power converter instead of real Lipo batteries... I have not seen lipo's with 4.2 volts per cell.... why do you test 50,4 Volts? as it is not available during flight....or i really need a long extension cord
Shane I wish you would do the same test away from the wall, I have tested Edfs against and away from a wall and it does make a difference in numbers.

Shane I've been in RC for over 30 years, the video I watched had the wall right behind the table.
The wall is against the table in this video.

From the video or pictures some time you always bigger than a building.
The only thrust number to look for here is the 3.7 Volt per cell rating! Unless you're using high-voltage lipos.. .
What battery did you use for the 50.4v test?

So they can generate fabricated & falsified specifications!!.. .
How did you connect this to a/c power?
GOOD
