I have no doubt that when testing the efficiency & power of these motors with laboratory equipment, they are better than the Emax motors on paper, but I don't think 99.999999% of pilots would ever notice a difference. I once tried replacing my $12 Velox V2 motors with a $26 set of Blackbird motors. I couldn't tell the difference at all. One difference I could tell was the price of the two motors when I had to replace one.
you cant get apples to apples comparison when testing motor efficency like that. thats why lab bench tests are the most objective and take out a lot of uncertainties. to make a fair and honest comparison on same setup, it would have to be tested in a controlled environment, ike a hover test (just like they test dji drones for the max flight time in hover position). that would make it as close to fair comparison as it can get in this situation. the efficency claims from Rosser are based on (electrical power supplied/mechanical power delivered). you cant reliably measure that in real world flight.
I definitely agree with your comment. As you said, lab data is just a benchmark because there are factors to take in consideration in the real world. I made reference to that fact in the video. As a result, the statement made by Rosser real does not mean much .

Very nice video. Liked. Watching from Brazil. All the best for you.

Need to test caddx new vtx with 2w power
