Hubsan Q4 H111

 

 

First Impressions:

The quad is 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.

When I flew the quad  for the first time new out of the box it would fly forward (more than just drifting forward) like you were giving it forward command. I then calibrated the sensors on a flat level surface and the flying forward was corrected. It now hovers very well.

 

 

Features:

  • Auto-Correcting (Auto-Upright)
  • 6 Axis Gyro
  • 360° Eversion: 4 Way Fliping (Left, Right, Forward & Backward), continuous roll for perfect action and great performance.
  • 6 bright LED’s. They are bright, especially at night. Makes it fun for night flying.
  • Quadcopter available in 4 different colors: White, Black, Green, Yellow, Red.
  • 2.4GHz controller. It has 3 sensitivity stages you can select by pressing down the right joystick. The LED will be solid green for Low Stage Mode (30% Rates), blinking green for Middle Stage Mode (60% Rates), blinking orange for High Stage Mode (100% Rates). Press (a)Elevator Trim/(b)Aileron Trim to change the sensitivity values and then hold down the elevator stick for 1 second to confirm or exit. In Expert Mode you can disable the flip function by pressing down on the left joystick.
    One beep = Flip Off, Two beeps = Flip On.
    The controller also has trim controls for Elevator and Aileron.
  • The Hubsan X4 H107L transmitter can be used with the Hubsan Q4 which is what I am using. You will then have a bigger size transmitter, LCD screen, programmable Dual Rates, and be able to turn on and off the quadcopter LED lights by pressing and holding down the lower throttle trim. In Expert Mode you can disable the flip function by pressing down on the left joystick.
    One beep = Flip Off, Two beeps = Flip On.
  • 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: – Hubsan 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

 

Pros:

  • 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.

Binding the quadcopter and controller:

First turn on the quadcopter power switch, place it on a level surface, then turn on the transmitter.
Push the left throttle lever to the highest position, and then pull it back to the lowest position. You will hear two beeps and the LED light will stop flashing and stay on solid.

 

Calibrate The Sensors:

1. Par the controller and the quadcopter.
2. Put the quadcopter on a level surface.
3. 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.

 

Transmitter Stick Calibration:

Mode 2:
Push both sticks to the upper left position and hold. Then power on the transmitter.
Rotate both sticks twice. Hold down any trim until the LED on the transmitter blinks red, indicating successful calibration.

Mode 1:
Push the left stick to the upper left position and right stick to the upper right position and hold. Then power on the transmitter.
Rotate both sticks twice. Hold down any trim until the LED on the transmitter blinks red, indicating successful calibration.
