I have done Dynamic Soaring in over 55mph, and quad flying in over 25mph with the right equipment.

Broken props are part of the process  :D It's amazing how antennas can find their way into the props  :D

DYS BE1104 4000kV - Props?

Firstly, this post is about the 4000kV motor, not the higher kV versions, OK. Used with DYS BLHeli 10A ESCs.

I have these on two Diatone ET 150/160 (quite a while now!!). The big plus of this set up is the length of fight times, which is way beyond most "modern" set ups. I use 500mAh 3S Sports Hall, 850mAh 3S outdoors.

These motors are/were advertised as needing the DYS 3x2 two blade props, and there seems little doubt these are about right, but, and its a big BUT, those props are SOOOOOO fragile. TOO fragile!  They are two screw and push on shaft type.

I have tried a couple of others without finding anything better that does not cause worse issues elsewhere!

Anyone used this 4000kV motor/esc setup, and found a better prop?


I still have a set of these dys 1104 4000kv on a kt100 frame in a box somewhere.... I was using Gemfan 3025 bi-blades for a 10+ minute runtime with 450mah 3s


maybe I should dig it out and drop in a crossfire rx on there....

Thanks very much for this. Had to wait for the slow boat to get supply, arrived and fitted this morning and they run on both my 150 and my 160 Diatone ET frames with DYS 1104 4000kV motors with DYS 10A BLHeli very well.

Look much stronger than the feeble DYS props, and the performance is better.   ~~
