The following is a guest piece written by Chris Szekeres, owner of Tiny Drones.
Your RC Transmitter — it may feel familiar, like a gaming controller, or even a steering wheel. But the amount of information you need to successful know your RC transmitter is also quite different from what you’re used to.
Here’s your guide to how your drone controller works and how it can give you a better understanding of flying overall. We are going to use the Hubsan X4 controller for reference throughout this article. You can check out Tiny Drone’s Hubsan X4 Review to learn about the drone itself.
Yaw & Throttle
The left stick on your controller is what handles the “yaw” and “throttle” of your drone. When you toggle this control stick left and right this will cause the drone’s front to turn along the x-axis in that direction. This is generally used to adjust where you want your unit to turn to.
The left control stick, when moved up and down, will control the “throttle” of your drone. The throttle allows your drone to be completely at rest, move at full speed, or even remain completely stationary in the air. If your drone has a camera built in, you can use this to position your drone, to get a birds eye view.
Roll & Pitch
The right stick on your controller is what handles the “roll” and “pitch” of your drone. When this control stick is toggled left and right your drone will “roll” on its side in the same direction. This can be used to navigate your drone on the X-axis. Be aware of all local hazards such as trees and light posts!
When you move this control stick up and down it will control the “pitch”. The pitch allows the nose of the drone to be pointed up and down. You are able to use this to both ascend and descend while in the air. This allows for more control than using just the throttle.
Trim & LCD Screen
After opening up your first drone, the unit may tend to “lean” to a specific direction. This can be caused by many factors, but can usually be attributed to poor weight distribution. This can also be caused because of an uneven power coming from individual motors. The “trim” buttons are used to compensate for this by allowing you to make adjustments to the power of each motor.
On the “LCD Screen” of the controller that there are two horizontal and two vertical bars. All of these bars will have a black notch in them. These bars will show how much thrust is being put out by each motor on the drone. By adjusting these “trim” buttons, the notches in the bars will move. The farther they move right the more power they will put out on the corresponding motor. This will allow you to have a more balanced flight.
If after your first flight you notice the drone is crashing on its front or side often, chances are you will need to adjust the trim buttons. This will help to correct the drones flight.
