These motors are okay, however the leads are contained within a single insulated cord. Not sure how long they'll last before they heat up and short out.

A good choice for outdoor use!
O.k., not one allone. But 4 of them together power a model of 200g absolutly satisfying.
The only problem to solve is the props.
There are airscrews needed with small diameter and huge pitch, 2,16"x3" e.g.
But thanks to 3D-printing this is not longer a problem.
Birds like the Armstrong-Whitworth "Atalanta" with a span of 55 cm are possible.
As I said: outdoors!

I have done some thrust testing with various propellers on the AP03-4000kv motor in the video below

youtube.com/watch?v=6WMros9ZCjA

Works good on a 1s LiPo system with certain props and batteries like GWS 5030 prop and 160mah Nanotech on a XP3A ESC.

It gives about 30 grams of thrust on 1 cell with a 4025 GWS prop.
Some wobble in the bell, but it seems to run smoothly enough.

Best in 3 Gamm class. Combine the 4000 KV with an Kyosho Prop (e.g. Fly Baby ) result 45 Gramm thrust with 1 cell 160mah/3,7V 1 Gramm HK esc. application and the machin runs about 9-12 Minutes full throttle.

You have to ream up carefully to install he prop!

I use this powertrain in a DIY Motorspatz 600mm wingspan 54 Gramm flying weight.
