... at the beginning of climbing I found 153A = about
3000watts.after 10 sec and under full throttle only 1900 watts are needed to
hold the vertically speed of 50m/s.after motor cut off climbing is more than
100m! ...

Hello Ron
Do you know if somebody built an outrunner very slim and log for slim fuselages?
For example, a good slim commercial outrunner with correct dimensions for slim fuselages is the hyperion G2220.

I have no links for you, but it's no problem. Howewever, you do need an extra bearing. See e.g. the Torcman 350 'Triton' series:
TORCMAN Brushless Motoren
-> TM350 & TM430 Serie

Or a shaft extension

42mm... this is still a problem for small fuselages... a diameter of 42mm is to big for a lot of fuses. And shaft extension stoles some centimeters of space.
Also Prinz said:
"F5B: I don't think, you will get such motor into one of these actual boomstick- bodies!
I used a really old type from brushed motor times".

If I will have time in the future, I will try to make a project of long and slim LRK with 20x4.5x2 magnets (or longer, coupling the magnets).
