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.Gut fr Depron HallenfliegerA 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
Works good on a 1s LiPo system with certain props and batteries like GWS 5030 prop and 160mah Nanotech on a XP3A ESC.could only get this working for a few mins. wires seem way to thin to work with. need to be slightly thicker HKIt 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.非:常:に:良:い:製:品:、:非:常:に:良:い: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.I use this motor AP03 with 5A 1S ESC.
It works fine with Lipo single cell.
and i rebind the wire and work fineNice running little motor, not what I had hoped for power wise on 1s.
