DYS 1404 BE1404-4300KV & 6000KV 2-4S Brushless Motor


I will soon be running thrust tests on the 4300KV variant of this motor sent in by DYS for review. It's going to be interesting to see how well these can spin 2" to 3" propellers and how these tiny new motors perform as far as flight times and flight characteristics. Also, it'll be interesting to see what configurations on your builds you guys come up with (props, frame, LiPo size, electronics used, and AUW). Recently, we only had (for the most part) 1104 to 1106 motors. There have been several new offerings for this class size and now other micro size motors coming out from other manufacturers such as 1402, 1107, 1108. The flight performance of these micro builds has improved quite a bit with the miniaturization and introduction of FC's and FPV components.

Thrust tests & motor overview coming soon (Test results will be posted in about 2 weeks - sorry for the delay, lots of motors on queue for testing, I'll try my best to speed up testing)

EngineerX: Saw these on BG. I guess 1404 is like a 1304 on steroids. Comparable to when T-motor went from 1306 to 1406 on the original F20. Very curious to hear how they do in your testing!

Yes! like a Hans & Franz pumped up 1304 !
I just finished testing a 1304-5000 and also got a 1304-4000 that I'll run on the thrust stand as soon as I get a chance after testing this one. I'm also curious to see how they compare and also see, at least on paper, which motor has the best performance: 1104, 1105, 1106, 1108, 1305, 1402, 1404..... all of a sudden there's too many choices

I think 1304 are probably the most under-appreciated micro BL size. Simplicity of t-mount, like 1105/1105, combined with extra torque and efficiency of 13xx size, yet with lower weight. Hopefully, these 1404's will be just as good.

The number of available motors sizes has gone out of control! My suspicion is that manufacturers are trying new sizes just to sell more gear to curious consumers. However, from time to time, they discover a gem.

LoL ..... It's always a laugh to watch those skits.
Well, looks like the 1404 is just as good as the 1304. A little bit better than the 1106-4500KV in terms of overall thrust. Armature feels sturdy and 2mm shaft should hopefully be strong enough to survive most crashes.

EngineerX: Appreciate your review notes and thrust tests on this BE1404-4300KV!

Interesting that it has the 4x12mm mounting pattern, like the larger 1306/1407 motors, rather than 4x9mm of 11xx and 1304. This might show it's intended as a lower weight option for the higher power 3" frames, rather than a high-power option for 11xx frames.

The other spec that struck me is the 9g weight. That's roughly 50 percent heavier than the BrotherHobby 1402 (6g weight). Again, this leads me to believe the BE1404 is positioned to contend with 1306/1407 motors, rather than lighter 11xx options.

I think that's right on the money, Aimed at light frames meant for 1304/1407 due to that mounting pattern.
A lot of the weight comes from that extra 2mm of stator height. I've noticed motors gain more weight when going taller on the stator as opposed to going with larger diameter since magnet weight has to increase as well as lots of the iron on the laminations.

Interesting note on the increased weight of taller motors due to longer magnets and iron core. I guess that marks another advantage for shorter pancake type motors.

I wish this 1404 motor would come in a 3200KV version and we could get efficient 4" t-mount props for it. There's a new 1404 motor from RotorX as well. But no 4" props for it either, unfortunately.

i have to note that im loving my 3600kv 1407 on the new hq 4 inch tri props, gobs of power, more than my 5 inch and i can get 7 minutes of light acro. not sure a smaller motor would have enough torque. i do think they are too heavy for my 3 inch though, i have the new 3 inch rotorx props coming for my 1304s, should be sweet.

That's likely but the 1402 with its almost 50% less weight also is a directnreplacement to a 1407/1408 motor as its more agile and actually may be faster than both my America themed BH catylystmachinework 1407 4000kv and f20 v2 liteweight builds and they even get to use 3076 triples and 3054 quad props though 1402 gets 3044tx.
Dont let the weight fool you.
Appears the dys needs more voltage with its lower kv to have similar numbers as far as thrust to 1402 and really 1402 thrust is likely much higher with its smaller lipo due to both 8100 and 9500kv take 3s like a walk in the park and run 3044tx triples so most likely producing about same 600 or so grams that the best 1407 motors are pulling on 4s with 3in props pretty much on top of being very efficient.
Gonna be hard for the dys to stamd up to but I'd sure like to buy a set to try out.
If The higher kv could take 4s and a 3025 or 3044tx prop that could make it worth the extra weight of the lipo.
So many goods coming out wish they'd all just be for sale no preorder.
Ml
Might as well get a direct withdrawal from my account from motor company's for new motors,would save time.


Engineerx//////,
Do you have a full set of these dys your flying or just a test motor?
Just wondering in flight what they are like,temps and capable voltage.
