## **Introduction**
The E-flite RC Airplane UMX Timber X BNF Basic is a versatile and exciting remote control aircraft that offers an exceptional flying experience. With advanced features such as AS3X technology and Safe Select, this model is perfect for both beginners and experienced hobbyists. In this article, we will explore the various aspects of the UMX Timber X, including its design, flight performance, battery options, and more. So buckle up and let’s dive into the world of this incredible RC airplane!

## **Understanding the UMX Timber X BNF Basic**
The UMX Timber X BNF Basic is a Bind-N-Fly (BNF) remote control airplane, meaning it comes pre-assembled and ready to fly with minimal setup required. This particular model does not include the transmitter, battery, and charger, allowing users the flexibility to choose their preferred options. With a wingspan of 570mm, the Timber X is compact but packed with features that make it a standout in its class.

### **The AS3X Technology**
One of the notable features of the UMX Timber X is the inclusion of AS3X technology. AS3X stands for “Artificial Stabilization – 3-aXis,” and it is a gyro-based system that helps stabilize the aircraft during flight. This technology utilizes accelerometers and a computerized control system to automatically make adjustments, compensating for external factors such as wind gusts, turbulence, and other disturbances. The result is a smoother and more stable flight experience, especially for beginners who may be learning the ropes of RC flying.

### **The Safe Select Feature**
Another key feature of the UMX Timber X is the Safe Select feature. Safe Select is a flight envelope protection system that allows pilots to choose different flying modes based on their skill level. The three modes available are Beginner, Intermediate, and Experienced. In Beginner mode, the aircraft has limited bank and pitch angles, making it easier for novice pilots to maintain control and prevent unintentional stalls or crashes. Intermediate mode offers slightly increased maneuverability, while Experienced mode gives the pilot full control over the aircraft’s capabilities. The Safe Select feature provides an added layer of safety and confidence, particularly for beginners or those transitioning from smaller RC planes.

## **UMX Timber X Specifications**
Before getting into the finer details of the UMX Timber X, let’s take a quick look at its specifications:

– Wingspan: 570mm (22.4 inches)
– Length: 477mm (18.8 inches)
– Flying Weight: Approximately 170g (6.0 ounces)
– Motor: Brushless Outrunner
– Battery: 2S 7.4V LiPo (not included)
– Recommended Transmitter: Spektrum DSMX/DSM2 with dual rates and exponential (not included)

### **Design and Construction**
The UMX Timber X features a sturdy and lightweight construction that is optimized for aerobatic performance. Its airframe is made of durable foam, which can withstand minor impacts and provide good overall rigidity. The aircraft incorporates a high-wing configuration with large flaps and ailerons, allowing for improved control and maneuverability during slow-flight and short takeoff and landing (STOL) operations. It also features functional LED lights that enhance visibility during low-light conditions or night flying. Overall, the design and construction of the UMX Timber X combine stability and durability with agility and aerobatic capabilities.

### **Flight Performance**
When it comes to flight performance, the UMX Timber X does not disappoint. Thanks to the AS3X technology and the well-designed airframe, this RC airplane offers a smooth and precise flying experience. It is incredibly responsive to control inputs, allowing for precise maneuvers and graceful aerobatics. Whether you’re performing loops, rolls, or inverted flight, the UMX Timber X remains stable and predictable.

### **Aerobatic Capabilities**
One of the standout features of the UMX Timber X is its aerobatic capabilities. This RC airplane is designed to perform a wide range of aerobatic maneuvers, including rolls, loops, knife-edge flight, and even harrier rolls. Its high-power brushless motor provides ample thrust for vertical climbs and exciting maneuvers, while the large control surfaces enable crisp and precise control. Whether you’re a seasoned pilot looking to push the limits or a beginner eager to explore aerobatics, the UMX Timber X is more than capable of delivering an exhilarating flying experience.

## **Battery and Charging Options**
As mentioned earlier, the UMX Timber X does not come with a battery or charger included. However, it is compatible with a 2S 7.4V LiPo battery, which offers a good balance between flight time and power output. When choosing a battery, it is essential to consider the capacity (mAh) and discharge rate (C-rating). Higher capacity batteries will provide longer flight times, while higher C-ratings will offer increased power output. It is recommended to use a battery with a capacity of at least 450mAh and a C-rating of 30C or higher for optimal performance. As for charging, a compatible LiPo charger is required to charge the battery safely and efficiently.

### **Compatible Transmitters**
The UMX Timber X is compatible with Spektrum DSMX/DSM2 transmitters equipped with dual-rate and exponential settings. This compatibility ensures a seamless connection between the transmitter and receiver, allowing for precise control and reliable signal transmission. If you already own a Spektrum transmitter, you can simply bind it to the aircraft and start flying. If not, you will need to purchase a compatible transmitter separately. It is important to ensure that your transmitter is set up correctly and that you follow the necessary binding procedures to establish a secure connection.

## **Tips for Flying the UMX Timber X**
If you’re new to flying the UMX Timber X or remote control airplanes in general, here are some useful tips to help you get started:

1. Start in Beginner mode: Begin by flying the aircraft in Beginner mode, especially if you’re new to RC flying. This mode limits the aircraft’s maneuvers and provides a safety net to prevent unintentional crashes.
2. Master the basics: Spend some time practicing basic maneuvers such as takeoff, landing, and flying in a straight line. Familiarize yourself with the controls, and gradually increase your comfort level before attempting more advanced maneuvers.
3. Use gradual control inputs: Avoid jerky or abrupt control inputs, as they can destabilize the aircraft. Instead, use smooth and gradual movements to maintain stability and control.
4. Fly in suitable weather conditions: Choose calm and clear weather for your flights. Strong winds or adverse weather conditions can affect the stability and performance of the UMX Timber X.
5. Fly in open spaces: Find a suitable flying location with spacious open areas, preferably away from obstacles such as buildings, trees, or power lines. This will give you more room to maneuver and reduce the risk of collisions.
6. Take note of flight time: Keep track of your flight time to prevent draining the battery completely. It is advisable to land the aircraft before the battery reaches critically low voltage to avoid potential damage.
7. Practice with a simulator: If you’re new to RC flying or want to improve your skills, consider practicing with a flight simulator. Simulators allow you to experience flying in a realistic virtual environment, helping you build muscle memory and develop better piloting techniques.

## **Maintenance and Care**
To ensure the longevity and optimal performance of your UMX Timber X, it is essential to perform regular maintenance and care. Here are some key maintenance tips:

– Keep the aircraft clean: After each flight session, gently clean the aircraft to remove any dirt, dust, or debris that may have accumulated. Use a soft brush or cloth to avoid damaging the foam or other delicate components.
– Check for any damage: Inspect the aircraft for any signs of damage, such as cracks, dents, or loose parts. Repair or replace any damaged components promptly to avoid further issues.
– Store properly: When not in use, store the UMX Timber X in a dry and dust-free environment. Avoid exposing it to extreme temperatures or direct sunlight, as these can degrade the foam and other materials over time.
