- Thrust test of the Happymodel SE 0703 15000kv brushless motor.
Motor burned out while testing 65mm propeller on 2S battery. R.I.P.
Thrust test datasheet and chart: bit.ly/Happymodel0703ThrustTes...
Can be purchased @ Banggood: bit.ly/Banggood-Happymodel-SE0...

Nice testing rig found your channel on banggood i watch your videos now and real life test's really help with choosing a right motor for my applications thanks
You are welcome! Thanks for feedback!
Really great tests, dude. Really good! 😊
Thanks, bro. This test was the last spin for this little motor. Now it is R.I.P. :)
Montis Oh... That's too bad. 😕
No problem. Lesson learnt. Moving on. Next on the list - Happymodel SE0706
Interesting... and sad 😞😞😞 great test! I’m looking forward for brushless whoops in 2S 🤩🤩
Thx for the review. appreciate it
Great. Thank you
What brushless motor would you recommend for 48mm quadblade props with 1mm mount holes , I can drill them to 1.48mm for bigger motors but I have so many of them laying around I want to use them , I also have a lot of the 40mm quadblade props that the beta75x uses
This kind of video that i looking for..... do more... 😆
I Just Sub You.
Thanks for your feedback. For sure I will do. I have various 0603 and 0703 motors waiting to be tested! But first some 110x motors.
Hi there mate. just wondering if you could tell me if those measurments (eg KingKong 40mm) are the radius or diamiter of the fan?
Cheers :)
Hi there. I use only diameter measurements in prop size.
Very knowledge . . . Can you please suggest lite weight best motors in thrust range 125g to 180g , in 1s and 2s
It depends on your needs. For that thrust range I would suggest 1103 motors with 7000-8500Kv on 3S. Or 1103-1104 motors with 10000Kv on 2S.
Hi sir. This motor, have bearing or else!? Thanks
No, this motor does not have bearings. Only brass bushings. And this motor is fragile! I've broken one while removing the prop.
I'm building custom Snapper 7 with these motors now.
@@MontisTube Do you mean there is no bearing in this particular model? Because on RaseStar's site and Banggod says they are have bearings (Powder metallurgy oil-contained bearing with low noise). At least it conserns models BR0603B Racing edition, BR0603B Green Edition, BR0603B Fire Edition (BR0603C don't). The same rules about 0703 size.
@@ZenoFromTheElea no, no ball bearings, just bushings. Look at those "oil-impregnated bearings" here:

Happymodel SE0603 motor btw what is the most efficient propeller that gives highest g\w
Black turbine KingKong 65mm props are unbeatable in terms of efficiency! But they are big ones and not always fit into the frames.
Montis i got space it's a big one
Black turbine good. Then use KK 65mm - they are the best.
You just made me think of another test - cut the KK 65mm props to other sizes and compare the efficiency with other props on the test rig. On the list now.
Montis KK65mm i will try them out thanks for the info can't wait for next video
Crashed my snapper7 today and broke a motor shaft... the prop popped out with piece of shaft in it
So sad...
Yes, they do broke in crashes. Good thing they dont cost too much :)
why this type se0603 so fragile, i damage my motor 3 pcs only in 2 weeks play, every day 30 minutes i play, each 2 minutes x 6 batt (2 times)
Yes, they are very fragile. I managed to destroy my first motor when I tried to remove the prop. Snapped the bell off the shaft... Try the Racerstar 0603C/0703C motors maybe they are more durable. I have ordered some for testing.
@@MontisTube Racerstar 0603C/0703C durable because they haven't bearings?
What do you use to power the motor?
Usually a freshly charged > 1000mAh battery or a few smaller batteries in parallel. In real life the voltage sag will be greater and thrust will be a bit lower.
@@MontisTube thanks! I was working on a project and was wondering how much power it would need so I didn't burn the motor out.
Where can i buy these small motors
There is a better motor now Happymodel SE0802. I would recommend to look for it.
For example you can buy them on BG: bit.ly/Banggood-Happymodel-SE0802-Brushless-Motor
If i understand correctly, 0703 motors are not recommended for 2S, as they are clearly not efficient.
Yep. Not recommended for 2S. You got it right.
IF They don't running hot on 2s they would work!
The major problem is that the Prop size MUST shrink down, so next times don't use the perfect 1s prop at 2s the poor motor could be alive if the prop was cut to 45mm or 50mm
Nice work, my smallest motor was 1102
So I definitively try an 0703 👍
Just for science
You are right also. They COULD work on 2S but with the smaller prop. The bad thing is these motors are not efficient on 2S. I would go with 0706 for 2S.
@@MontisTube I've heard 0802 motors are very efficent too...
Heard that too. Also happymodel 0803 should be good. Need to try one. 0802 are the cheapest @ the xt-xinte.com
Rip motor 🤣🤣🤣
Testing to the limits
you do wrong test. if you accelerate motors fast, they will need more power than usual. you must wait 5 secs at each step. for example 5 secs at 1 amp, 5 secs at 2 amp, 5 secs at 3 amp current and look result. all these results faulty.
I trust a man with the NASA logo :)
