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.

 

Review

 

First Impressions:

The Infra X was smaller than I thought it would be which is good so I can fly it indoors.
It looks nice and feels well built.

 

Overview:

Quad with a 3-Axis and 6-Axis gyro that can be changed in flight using the FMOD switch or another switch that you choose like the MIX switch or AUX knob.
It can do 3D rolls and flips. Switch to 3-Axis for this.

This is a quad with an Infrared Obstacles Avoidance system which helps to avoid an obstacle automatically.
There also is an Ultrasonic Altitude Hold system which enables the quad to keep flying at relative height.
This quad runs on the Devo transmitters. It uses the same battery as the V120D02SV2.
The motor booms are the same size as the Ladybird booms (3mm square tube) but they are longer in length.
The Infra X use the same blades as the Ladybird.
The Infra X motors are bigger than the Ladybird motors.
I got the yellow version and can see it a good distance away from me.

The canopy feels strong.
The motor arms that are the landing gear are not very strong. I busted one already crashing onto flat carpet.
The battery plug is extremely hard to get out! I almost had to use pliers.

 

First Flight:

I took it for a test hover and flew towards my wall. The quad deflected off the wall every time I got close to it.
It gives a short burst of thrust to avoid a wall or obstacle.
The Altitude Hold is strong flying over a table or couch. It sends the quad up 2-3 feet high with a quick bust of thrust. I have almost hit the ceiling too many times.
Just flying normal in my living room if I get near the edge of a table but not flying over it, it sends the quad shooting up towards the ceiling.
The Infrared Obstacles Avoidance works well. It doesn’t shoot the heli across the room.
You can see in my videos how the Infrared Obstacles Avoidance and Altitude Hold work.

I don’t recommend the Infra X if you are buying it for the obstacle avoidance which only works if you drift or fly slow into the wall like in my videos. If you fly normal speed or hard into a wall or object the quad will hit it every time. The obstacle avoidance just can’t react fast enough. If it did it would be great for indoors and beginners. Also the quad is very heavy.

 

Pros:

  • 3 axis mode and 6 axis mode
  • 2 bright LEDS in the back
  • Firmware can be updated
  • Ultra stable, responsive, and smooth flying

Cons:

  • The Altitude Hold is too strong. It sends the quad shooting up almost to the ceiling from a hover at about 4 feet high.
  • The obstacle avoidance doesn’t react fast enough. It works well if you drift or fly slow into a wall or object but if you fly at normal speed or fast into a wall or object the quad will crash into it every time as the obstacle avoidance can’t react fast enough.
  • The motor arms that are the landing gear are not very strong. I busted one already crashing onto flat carpet.
  • The battery plug is extremely hard to get out. This is the same with the V120D02SV2, Walkera needs to address this problem.
