Estes Proto-X Nano Quadcopter Review




RC Pro Review by: Tom Zadar



Estes Proto-X Nano Quadcopter

This is the American version re-brand of the Hubsan Q4 H111 quadcopter.



First Impressions:

The quad is very small and light. It is super stable and ultra responsive! The yaw rate on it is fast. The quad is fast! You can really zip around with it. The small size, fast response and being so stable makes this a great quad for indoors or outdoors in light wind.




  • Auto-Correcting (Auto-Upright)
  • 6 Axis Gyro
  • Execute flips (Left, Right, Forward & Backward) and other mild-to-wild maneuvers
  • 6 bright LED’s. They are bright, especially at night. Makes it fun for night flying.
  • Quadcopter available in 6 different colors: White, Black, Green, Yellow, Red, Purple.
  • 2.4GHz controller
  • Three flight modes: EASY Solid Green, MEDIUM Flash Green, EXPERT Flash Red
  • The controller also has trim controls for Elevator and Aileron.
  • To perform Aerial Flips you must be in Expert Mode. Once you are in Expert Mode press down the left stick, you will hear continuous beeps.
    Next, move the right stick any direction and the Proto-X will flip that direction.
  • Low Voltage Cutoff – The quad will flash the LED lights. Land as soon as this happens. You will have about 30-45 seconds to land before it reduces the power quickly.
  • Charges the battery in 23 minutes. I timed this landing the quad as soon as the Low Voltage Cutoff came on 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.
  • 4-5 minutes flight time.



Flight Time: – Estes 4618 3.7V 100mAh Lipo – Fully charged voltage: 4.17V

  • 2 Minutes: 3.86V
  • 3 Minutes: 3.77V
  • 4 Minutes: 3.70V
  • 4:25 Minutes: 3.70V – Low Voltage Warning – LED’s on Quad flashed
  • 4:55 Minutes: 3.62V – Quad quickly lowed power to land



  • Ultra stable, smooth flying and super responsive
  • Fast yaw rate
  • Good flight time for a small battery
  • Small enough to fly in any size room
  • Bright LED lights


Cons: None so far


* Note: The blades can sometimes fly off in flight. See my post below on how to fix a loose fitting propeller with Nail Glue, CA, Dental Floss, Elmer’s Glue, Contact Cement and UV Adhesive. I use the CA method myself and it works great. I have also used it on my micro helicopter tail blades.

Link The Controller

Hold the throttle stick at full down and turn on the controller.
Wait until the red LED turns green.


Calibrate The Sensors:

1. Turn on the controller and the quadcopter.
Place the quadcopter on a flat surface.
2. Hold the left stick to the lower right. At the same time, quickly move the right stick left and right several times until the blue LED’s flash.
Test the model to see if it will hover without drifting.
If the model is still drifting, try putting a thin piece of cardboard under the motor or motors in the same direction that the quadcopter is drifting.
Perform the sensor calibration procedure again.



* My camera broke so I had to use my smartphone for pictures and video.
