Walkera QR Ladybird V1 Quadcopter Review


Walkera QR Ladybird Quadcopter



RC Pro Review by: Tom Zadar


Transmitter Setup Guide

See my Transmitter Setup Guides for transmitter setup. The setup guides have all of the transmitter settings needed to make a model completely from scratch.
The Tx Setup Guides have different difficulty settings depending on which setup guide you choose. For Helicopters there are Standard Settings, Beginner Settings, 3D Settings. For Quads there are Standard Settings, Beginner Settings, 3D mode settings.
Each setup guide includes everything needed for setup including Model Type, Swash Type, Servo Reverse, Travel Adjustment, Gyro Gain, Throttle Curves, Throttle Hold, Pitch Curves, Pitch Curve/Throttle Hold, Subtrim, MIX, Switch Assignments, Dual Rate and Expo.
I added a bonus to every setup guide with a Dual Rate and EXPO settings guide I made for Helicopters and Quads.



Walkera QR Ladybird V1


First Impressions:

The Ladybird looks nice. It is small in size and it fits in my hand. It is very light weight.
It feels well built and should take a crash pretty well.
It has a unique sound to it with the 4 motors.

I have never flown anything but helicopters for over 5 years so I was curious how a quad would fly.
I would say it is a bit like a coaxial helicopter in a way but also very different than a helicopter.
The Ladybird is ultra stable and very smooth flying. It has good power with the stock motors.
After I added some D/R and Expo I was able to fly it good for the first quad I have ever flown.
The flight time is very good. I was surprised that the stock battery got the same flight time as the Hyperion 240 mah 25C battery and had the same power.



  • Ultra stable and smooth flying.
  • Long flight time.
  • Responsive and super fast forward flight.
  • Replacement parts are not expensive.
  • 6 axis mode and 3 axis mode for the newer version firmware 2.0 and higher.
    Firmware version number is on the bottom of the RX.
    3 axis mode was added for 3D-Flipping. Older version firmware only has 6 axis mode.


  • None so far.

  • The Ladybird has been doing well in a crash. I have crashed it on my hard wood floor a few times with no damage.
    I did split 3 out of 4 motor booms flipping it outside and crashing hard into the cement a couple of times.
    Also bent and twisted the blades too. The booms may have split when I hit the cement and not the grass, not sure.
    The blades bent on the grass though learning to flip it.
    I bent the blades back and it hovers and flies well even with the 3 split motor booms.



I have found out that using the telemetry eats up the battery time.
I went from 5 full minutes of flight time on my Master CP with telemetry
inhibited in the TX to 1:25 minutes flight time with the telemetry enabled.
I found the same thing with my Mini CP, 1:25 minutes flight time with the
telemetry enabled and 3 minutes flight time with the telemetry inhibited.
My friends Mini CP had the same results as I did with telemetry inhibited and enabled.
