Cheerson CX-Stars Quadcopter

“The world smallest and lightest RC Quadcopter”

 

 

First Impressions:

The Quadcopter is extremely small and light. It is super stable and has good response.

 

I also have the Hubsan H001 Q4 SE Quadcopter. It is almost exactly the same size and weight of the Cheerson CX-Stars.
The H001 Q4 SE has “much faster” motors than the Cheerson CX-Star.
The H001 Q4 also has a faster yaw rate and faster response than the Cheerson CX-Star.

I compared the two quadcopters side by side switching back and forth between the two.

 

 

Special Notes:

  • The transmitter battery compartment contacts are selective on the length of the battery used.
    Lengths of batteries vary slightly from different manufactures.
    I have 3 different transmitters. One of them is good with any brand battery I use, the other two are not. Using Duracell batteries they would not work due to a slightly loose fit, but they worked great with Energizer batteries. If you get one of the transmitters that the batteries fit slightly loose use another brand battery.
    I tried stretching out the negative battery springs to make the battery fit tighter but it didn’t work.
  • The Quadcopter packaging should have a clear round seal on the bottom about the size of a nickel.
    If the seal is broken or missing, you have a used Quadcopter. That is what happened to me.
    The Quadcopter that I purchased was missing the clear round seal. The Quadcopter was damaged, cracked orange shell by the motor as seen in the pictures below and the battery was defective.
    The battery would only fly for about 35 seconds on a full charge.
    I contatced the seller and they sent me a new one for replacement. This time the package had the clear round seal packaging seal on it.
  • The Quadcopter is branded under many different names and at many different prices. There are some dealers/sellers that have doubled or tippled the price.

 

 

Features:

  • Auto-Correcting (Auto-Upright)
  • 6 Axis Gyro
  • 360-degree rolling function – Execute flips left/right and forwards/backwards
  • Transmitter includes storage for the drone
  • 4 bright LED’s
  • 5 minutes flight time
  • Charging protection
  • Charging time: About 30 minutes
  • Motor: Brushed Coreless F4 motor
  • Quadcopter Battery: 3.7V 80mAh, lithium-ion battery
  • Transmitter battery: 2 x AAA battery
  • 4 Channel control – Mode 2 (Left Throttle Hand)
  • Remote Control Range: 20m – Flight Height: 20 meters
  • 2.4GHz transmitter with 3 modes:
    1. Junior Mode (Beginner Mode) – One beep pressing down on left joystick (Throttle Stick)
    2. Intermediate Mode – Two beeps pressing down on left joystick (Throttle Stick)
    3. Head Locking Mode (Headless Mode) – Three beeps pressing down on left joystick (Throttle Stick)

Charges the battery in 25 minutes connected to a desktop computer USB port which provides 5V at 500 mAh.
I timed this landing the quad as soon as the LED lights started to flash and after letting the battery cool down for a while.
The USB charge cord has a red LED which will be on when it is charging and turn off when charging is complete.

 

Flight Time: These flight times were taken when the LED lights first started to flash.

I did not continue to fly until LVC (Low Voltage Cutoff) kicked in so you could fly another 15-30 seconds more after the LED lights start to flash. But be aware the quadcopter will land very fast once LCV kicks in. Also continued flying until LCV kicks in can shorten the battery life. It’s best to land as soon as the lights start to flash.

  • Flight #1 = 3:48 Minutes until LED’s started flashing
  • Flight #2 = 3:36 Minutes until LED’s started flashing
  • Flight #3 = 3:38 Minutes until LED’s started flashing

 

Thrust: 0.3 Grams

 

Pros:

  • Ultra stable, smooth flying and has good response
  • Good flight time for a small battery
  • Small enough to fly in any size room
  • Bright LED lights, good for flying at night

 

Cons:

  • None so far

Dimensions:

Quadcopter: 22 x 22 x 20mm

Transmitter Length: 10.8CM

Transmitter Width: 7CM

Coreless Motor: 4mm x 12mm, Shaft Size: 0.7mm x 4mm

Blade Size: 20.7mm (L) x 3.7mm (W) at the widest point on the blade and the hub length is 3.8mm

 

SETUP:

1. Switch on the power on the quadcopter and place it on a flat and level surface. The quadcopter lights will be flashing.
2. Switch on the power on the transmitter, after you here two beeps from the transmitter, push up the throttle stick, you will here one beep.
3. Pull the throttle stick back down, you will here one beep. The quadcopter is now armed and ready to fly.

 

Calibrate The Sensors:

1. Switch on the power on the quadcopter and place it on a flat and perfectly level surface. The quadcopter lights will be flashing.
2. Switch on the power on the transmitter, after you here two beeps from the transmitter, push up the throttle stick, you will here one beep.
3. Pull the throttle stick back down, you will here one beep.

“Do not give any throttle” The quadcopter is now armed and ready to continue on to be calibrated in Step #4 below.

4. Move the throttle stick to the left bottom corner, move the right stick to the left top corner. Hold both sticks at those positions.
The lights on the quadcopter wil start to flash. Keep holding both sticks at there current position untill the lights on the quadcopter are done flashing.
When the lights are done flashing release both sticks. The quadcopter is now Calibrated and ready to fly.

* Use a bubble level to get a perfectly level surface. The quadcopter gyros will always use the calibration setting you set for it as it’s reference point for level so make sure the surface is as level as you can get it.

If the quadcopter is flying/pulling to one direction after your have done the calibration, you can recalibate it again and put some paper in the same direction that the quadcopter is flying/pulling. So if the quadcopter is flying to the right, put some paper under your flat level surface on the right side to tilt the quadcopter to the left.
Then redo the calibration and test fly it and see how it worked.
This will be some trial and error on how much paper to use to counter the flying/pulling in one direction.
You can use sheets of paper, index cards, envelopes, business cards, etc.

 

 

I also have the Hubasn H001 Q4 SE quad. I did a review on it here on my website.

Here is a video comparing the motor speeds for the Cheerson CX-Stars and the Hubasn H001 Q4 SE.

Both of these are good quadcopters.
