This aircraft model is recommended for aeromodeling competitions due to its large size and good flying performance. The wings are made of lightweight EPS material, and it comes with a new style propeller and a dual-connect body, which is beneficial for take-off. Before installation, you can use transparent adhesive to strengthen the wings. If the wood strips are too tight to fit in, please sandpaper or lightly scrape them. When testing the flight, face the outside of the propeller, grasp the bottom of the wing with one hand, and rotate the propeller clockwise for 100-150 turns. Then, release the aircraft at a 45-degree angle upwards. If it shoots up, you can adjust the wings slightly backwards, and if it shoots down, you can adjust the wings slightly forwards.

The benefits of playing with radio-controlled models:
Children's hands-on assembly of educational toys can stimulate their innate desire for exploration and growth, creating a learning environment and a space for activity and exploration. This can help children to the fullest extent to develop their potential. The right choice can create learning opportunities for children, and its impact will last throughout their lives. When parents play with their children and provide appropriate guidance, they can help children in the process of play to understand knowledge.

Scientific Enlightenment:

The reason why an airplane wing generates lift is due to the principle of Bernoulli's principle, which was discovered by Daniel Bernoulli in 1738. In a fluid system, such as airflow or waterflow, the faster the flow, the smaller the pressure generated by the fluid. This is known as the "principle of Bernoulli," which states that the faster the flow, the lower the pressure. The airflow over the top of an airplane wing moves faster than the airflow below, resulting in a lower pressure below the wing than above. This creates a significant pressure difference, which "holds" the airplane up, and then the airplane takes off.
Let's get started and make a rubber band airplane together.

Science Project:

1. Prepare the necessary materials for the experiment, including propellers, wings, fuselages, and tail wings, etc.
2. Follow the instructions in the manual.
3, Install and debugging.

Scientific Principles:

The physical principle of elastic band powered aircraft is that when the elastic band is twisted in the opposite direction (doing work on the elastic band), it is gradually stretched, and the elastic band accumulates the rebound force of contraction, which drives the propeller to rotate (doing work on the propeller). This makes the aircraft fly. The working principle of the propeller and the aircraft is the principle of aerodynamics.

Scientific Exploration:

What is the scientific principle of rubber band planes?


Airplane Flight Technical Support
1. Inspect the model
Looking directly at the model's head, a properly installed model should not be twisted and should be symmetrical from left to right.
Section Two: Model Adjustment
In the absence of wind or with a gentle breeze, hold the center of gravity of the drone's body and gently throw the model. Adjust the distance between the wings and the tail as the model's flight posture changes. A wavy flight pattern indicates that the head is too light, and you need to move the wing forward; a downward dive indicates that the head is too heavy, and you need to move the wing rearward.
Section Three: Powered Flight
First, wind the propeller clockwise about 15 times, then hold the model with your right hand and support the propeller with your left hand, gently pushing it into the wind. Observe the flight trajectory, and a spiraling ascent is best. If the model's spiraling radius is too small, cut a small hole at the root of the vertical tail and bend it in the opposite direction. After the flight attitude is normal, wind the rubber band 200-220 times for large power flight. The rubber band should generally be in a slightly relaxed straight state. Whether to oil or not, I think it's okay. If you oil it, it will be slightly smoother, but the rubber band life will be shortened. The key issue is to adjust the center of gravity of the plane. The method is not to tighten the rubber band, and to throw it out directly from your hand in an environment without wind. The plane should not have obvious head or tail up. If it has a head, add weight to the nose. In addition, it is necessary to pay attention to the plane not having a tilt. If it appears, adjust the wings to correct it. Generally, when competing, you should throw the plane into the wind, and you don't need to use too much force. Especially when the wind is strong, if you give too much force, the plane will do a loop backward, which will shorten the flight time.

Love's Reminder:
Before assembling, please check if the circuit is unblocked and all the components are complete. Ensure that all contact points are in good contact. During the assembly process, be careful not to get glue on your clothes or skin. Keep the parts out of reach of younger siblings to prevent them from swallowing them by mistake! Do not play with them on your head, to avoid the model falling and injuring you!
