CL-0720-14 - coreless motor set, 7x20mm, speed: fast
If you want to turn your 7mm quad into a cruise missile, this motor is the ticket!
Check out this video to see the CL-0720-14 in action:
- Hobbyking Pocket Quad v1/v1.1
- Hubsan X4 107L
- WLToys v242/v252
- Walkera Ladybird
- probably a range of other micro quads. If you want to know what motor a particular model needs and dont see it on the list, please use the contact form and ask!
- operating voltage: 1.5-3.7V
- max. thrust: 26g (Hubsan X4 propeller)
- 1.8A load current at 3.7V (Hubsan X4 propeller)
- can diameter: 7mm
- can length: 20mm

- shaft length: 5mm
- weight: 3.4g
All motor packs contain equal amounts of clockwise and counter clockwise motors. To maximise performance and life span, dont run them in reverse!
Motor rotation and correct polarity is indicated by the wire color:
clockwise: red +, blue -
counter clockwise: white +, black -

I hope you can help me!
Installed them on my Hubsan X4. With the original motors, the x4 struggled to lift an 808 keychain camera and as a result I damaged a motor and the camera during a crash. I replaced all of the original motors with the CL-0720's and there was a noticeable difference in speed and maneuverability, so I tried flying with the camera again and it goes great! You have to throttle up almost full still, but it won't fall when you try to bring it down slowly, and the motors get quite hot, but that is to be expected.
To put it simply, More power = more fun.
I had trouble putting the x4 props on these, they were a bit tight. I installed the props on the original motors first to stretch the holes in them, and then installed them on the CL's and it was fine.
Waiting for the flight controller to be back in stock so I can order a few of them as well.
I am sure you will never go back to the original motors if you used this little devil.
To get more flying time I would recommend a bigger battery, lifting more weight is no problem.
(the original charger will support up to 500 mah)
Now it flies like a Rolls Royce. Great motors!

Total weight is 28.9 grams without battery. With a well-worn Skyartec 240mAh battery, it weighs 36.7 grams and gives 5:25 of moderately aggressive flying. With a used generic (blue) 380mAh battery from Banggood.com, it weighs 39.0 grams, and provides 6:45 to 7:00 minutes of fast backyard laps. This setup provides more punch and power than the stock WLToys V252, despite carrying a few extra grams of weight, so I’m very pleased.
I carefully tested these motors before soldering, having read MM from UK’s comment about polarity on the black and white (CCW) ones, and found that white is positive and black is negative, as advertised above.
On first installation, I thought I’d mounted the wrong props, as the quad wouldn’t launch straight up and kept trying to flip. No amount of calibrating helped. But after a minute of running, it gradually improved. It then seemed to become more responsive and faster over the following few flights. Perhaps the motors needed burning in? Or perhaps I just took a while to get used to the new toy.
(I had to desolder my motors to correct the above...)
