I ordered a bunch of 3.5″ props by accident. Then the 1707 motor came out so I built a new one to see what it would be like. I only flew two and a half packs on it. It’s far quicker than any 3″ I’ve seen and flies well with a Yi/GoPro as well, but after flying it I was reminded how much I prefer torque over revs. So it’s up for sale.
Here is the unusually popular IG post on it: [url]https://www.instagram.com/p/BHZSHOOALIR/[/url]
Here is the maiden and time lapse YouTube on it:

That’s about 20% (~$50) less than if you were to buy all the parts and build it yourself. Plus free shipping.
Performance is vastly improved over 1407 motors. Especially with an HD cam on board. Power to weight ratio is about 8:1 without an HD cam. Still however a lower powered 5″ or larger prop craft has far more bite into the air. This little one gets moving really quick when it builds up however.
These small high Kv motors are not ideal and all run very hot because there is no way they can reach anywhere near the RPM they’ve been would to produce.
It’s alright but just not my cup of tea. I’ve now attempted to pack the power of a 5″ craft into something smaller four times. I built this one day ago and only flew three packs on it but it’s going up for sale tomorrow. Though fast, I really have little interest in flying it. Better someone else make use of it…
