Last month I published a product review about the Blade mQX RTF quadcopter because I wanted to know if it is as good as people are saying. Many RC enthusiasts said that the one thing that made them love this RC multi-rotor was the fact that it was pretty stable and easy to fly, even when it is a 4 channel RC toy. I decided to investigate more about it and found that the component responsible for the stability of the toy is the AS3X 3-Axis stabilization system that is mounted on the 4-in-1 control unit. This little device seems to do a very good job since even when the Blade mQX is not a toy for beginners, because of the number of channels that it has, the AS3X system takes care of those variables that can give a hard time to the newbies and allows them to use this toy like advanced pilots. If you want to know why this is possible I invite you to stay tuned and learn more about the AS3X stabilization system here.
The stability of an RC flying toy is critical for the optimal operation of the device, without a stabilizer component the aircraft would inevitably crash as it would be literally impossible to control direction, pitch, speed, and landings. An RC flying toy is stable when the pilot is able to command an instruction via the transmitter and the aircraft performs that instruction as accurate as possible minimizing the effects of the environment or of the nature of the toy itself. This means that if the pilot activates the throttle with the intention of taking off the ship, this is what has to happen regardless of the wind or the weight of the toy. Take into consideration that the toy must be designed to operate in those conditions or you will damage it.
There are a few ways that most RC helicopters use to achieve stability and even when I have spoken about those on this blog, I want to give you a little refresh here:
Gyro system: This is a small electronic device that RC helicopters such as the Blade CX2 have these days, the gyro system detects all the forces that make the helicopter unstable and it triggers signals to some servos in order to counter act these forces and stabilize the ship.
- Tail rotor: The gyro system activates the tail rotor to counteract the torque reaction created by the main rotor blades of the helicopter and thus stabilize the aircraft. Depending on the number of channels the pilot can control this tail rotor with or without the gyro to stabilize the helicopter as well.
- Coaxial main rotor: Have you seen those helicopters with two main rotor blades? These are called coaxial helicopters and they say that these are the most stable RC helicopters of all. The double main rotor blade allows helicopter, such as the mCX2, to cancel the torque reaction caused by one main blade since the other is spinning in the opposite direction from the first one, that way the torque reaction created by each one is eliminated.
Recently another stabilization system was developed and the comments about it are awesome, this simple device is over delivering according to many hobbyists and here I want to presents some facts about it.
What is the AS3X 3-Axis Stabilization System?
The AS3X Stabilization system is a piece of technology developed by Horizon Hobby; it is the acronym of Artificial Stabilization 3 Axis and according to the comments of current users this little friend can make wonders in terms of stabilization and agility with a flying device. There is a saying in the industry that goes like this: “Bigger is better”, this is because big toys are more stable, but the AS3X stabilization system allows a small device to behave like a big one, this is especially important when flying outside with a little bit of wind.
Why would I like to have the AS3X stabilization system embedded in my RC helicopter?
There are very specific advantages of using the AS3X system, and here I want to highlight those that I find more relevant, and I will leave the others for you to discover them and come back and leave a comment on this post.
Fly like a big bird: The AS3X system is designed to provide the stability of a big bird to a small one; this is thanks to the fact that the AS3X takes full control of the aircraft and make it more stable and responsive even when it is a lightweight ship. It can achieve this thanks to a sophisticated combination of 3-axis sensing technology tuned by expert RC pilots.
- No bumps: One of the effects that you can observe when flying in a windy day, is that the aircraft experiences a bouncing movement; this is because the air current produces a bumping effect, but the AS3X takes this issue out of the scenario and allows you to manage and control the ship completely.
- Agile and Stable: Those birds designed to perform acrobatics typically will have stability issues and vice versa, the AS3X stabilization system expands the flight envelope so you never have to sacrifice none of these because of the other.
The AS3X 3-Axis stabilization system is an advanced technology that has changed the RC flying toys industry. At the end of the day this is what really matters and it is the end user the one who finally says if a product is good or not. The AS3X seems to be well accepted among RC pilots and based on their comments this technology is here to stay.
To your flight success!
