This is the first EDF I see where everything is done right:
1) fan is far from the edge. (try removing that tiny intake rim from a plastic edf and measure current. You will get up to 30pcnt difference!). The reason is incoming air stream must be properly formed and not get stalled on the edges like it happens on DrBadThrust fans where they ignored it.
2) 32mm motor is installed before the fan where air is colder and is not covered.
3) There's an airflow channel through the motor driven by inner blades inside the fan and Bernoulli pump (that half-cut cone at the back).
4) three bearings eliminate all vibration.
5) There's no fan adapter - it sits right on 5mm motor shaft.

This thing is designed to give you maximum thrust/power ratio, not just suck 80A for extra 200g thrust like many others.

Im blowen away at the quality for the price! Im using it as a starter motor for a pulse jet. Have yet to power it up, but I'm sure it will exceed my expectations for the job.
