I agree, not too impressive. My "ancient" WlToys 242 has better video. It's nice that the Dragonfly does waypoints, but that feature is of limited use if the video quality is nothing to write home about.

I guess that if you ignore the jello, the jiggling, the prop in the top left, and the gimbal roll axis apparently not working at all, it's not too bad.
Mind you since one of the so-called 'test videos' above is for a completely different drone (SG906), who knows what we are looking at?

140000 Watt for a single brushless motor? This drone can lift people?

Sales can mean a product is good, but can also mean it gets well promoted, so many people are convinced to get one, just because of the specs and promised performance. However, it's not uncommon for a product with specs that sound to good to be true for the price, to actually not live up to the high expectations. Maybe when some more real reviews appear, with actual camera footage, more can be said about the quality. "Advertorial" reviews are not the best source for information.

Indeed, Mavic Pro Motor's effect rate is 23.31W (11.1V/3.1A), KK13's 1406 motor is 25.16W, and pulling force will be about 190g as estimated from DJI technical data. Looks like effective motor; unfortunately, it seems to be around 1400KV-1600KV rating class at 7.6V operation, Prefer higher KV rating as racing drone like performance, it looks like long time flight drone like performance, as DJI's drones.

That makes more sense, so the reviewer didn't mean the motor has 140625.16W, but is 1406 type, and has 25.16W. Still makes me wonder if the reviewer really knows what he or she is talking about, or just repeating the specs, making a nice story with those, and throwing in some numbers to make it look even more impressive.

Low kv is to be expected, you don't need high rpm on a GPS drone, flight time and smooth running are more important than speed and fast cornering.
