I m a beginner playing with model airplanes, please point out the high fingers

Ha ha. I know that's what I'm playing

I've been playing for 5 years. First of all, you need to determine your future development path. Is it mainly aerobatic aircraft or gliders? Let me start with that. (Remote control available).

Stunt machine: It is mainly based on flying stunt action, and the main power is electric or model oil, which is more difficult to watch, but it is practiced! The aircraft model used at the beginning is P3A, which means that the aircraft has a small Venus, etc., generally an or engine, and you can upgrade to P3A-2 after about 1 to 2 years of practice, and there are Abro UIGI and so on, at this time, your investment is about 6000 to 10000 yuan.

Gliders: In terms of time in the air, it is divided into three categories, of course, there are many types of it, there are about dozens. It's relatively cheap for beginners, about 1,500 to 2,500 yuan.

Gliders are relatively easy to learn, but it is very difficult to really improve! However, the feeling of flying a glider is a real treat!!

ps.Airplanes can be bought online or in stores, and the ones in stores are ridiculously expensive, and if you practice your skills, you can make your own planes. It's even better than what's on the market! The world's top planes are all handmade.

pps.If you want to know more, you can go to the FAI (International Aviation Network) or subscribe to the "Aeronautical Model Magazine" (from Beihang University) The general newsstand is not There is a final word: At present, there are few good domestic aeromodel instructors Coach Lu Zheng of Henan, Coach Jin, Coach Li and others are the top people in the field of aerospace models in the world They have taught me Really powerful!

If you have questions, you can ask them

Is it to assemble or buy the finished product???

v Remote-controlled aircraft are generally controlled by remote-controlled equipment including: radio transmitter (transmitting radio signals), radio receiver (receiving signals).

Fixed-wing aircraft control the horizontal tail, vertical tail, and ailerons and flaps (which are not available in ordinary aircraft) through the transmitter to control the flight attitude of the aircraft.

It is generally believed that it cannot fly, and the model made in a certain proportion with the actual size of a certain aircraft is called an airplane model.

Generally speaking, the model that can fly in the air is called a model airplane, which is called an aeronautical model.

Second, the composition of the model aircraft.

Model airplanes are generally the same as manned aircraft, mainly composed of five parts: wings, tail, fuselage, landing gear and engine.

1. The wing ——— is a device that generates lift when the model aircraft is flying, and can keep the lateral stability of the model aircraft when flying.

2. The tail ——— includes two parts: horizontal tail and vertical tail. The horizontal tail keeps the pitch stable when the model aircraft is flying, and the vertical tail keeps the direction of the model aircraft stable when flying. The elevator on the horizontal tail controls the lifting and lowering of the model aircraft, and the rudder on the vertical tail controls the flight direction of the model aircraft.

3. The fuselage ——— the main part that connects the various parts of the model into a whole is called the fuselage. At the same time, the fuselage can be loaded with the necessary control parts, equipment and fuel.

4. The landing gear ——— a device for model aircraft to take off, land and park. There is a landing gear in the front, and three landing gears on both sides of the rear are called the front three-point type; There are three landing gears on both sides of the front, and one landing gear at the back is called the rear three-point type.

5. Engine ——— It is a device for model aircraft to generate flight power. The commonly used actuators of model airplanes are: elastic bundles, piston engines, jet engines, and electric motors.

3. Common terms of aeronautical model technology.

1. Wingspan - the straight-line distance between the left and right wingtips of the wing (tail). (The part that passes through the fuselage is also counted).

2. The full length of the fuselage - the straight-line distance from the front end to the end of the model aircraft.

3. Center of gravity - the point of action of the resultant force of gravity of each part of the model aircraft is called the center of gravity.

4. Tail arm - the distance from the center of gravity to the quarter-chord length of the leading edge of the horizontal tail.

5. Airfoil - the cross-sectional shape of the wing or tail.

6. Leading edge - the front end of the airfoil.

7. Trailing edge - the rearmost end of the airfoil.

8. Wing chord - the line between the front and rear edges.

9. Aspect ratio - the ratio of wingspan to average chord length. A large aspect ratio indicates that the wing is narrow and long.

Analysis of the elements and principles of practicing flying.

At the beginning, I would like to emphasize the elements and principles of basic flight practice, which are directly related to whether you can successfully master flying skills.

This is my copy of someone else's, take a look.

Make a model airplane.

1. Preparation of materials:

1. A paulownia strip with a length of 250 mm, a width of 15 mm, a thickness of 3 mm and a length of 90 mm and a cross-section of 3 square millimeters (in a handmade bag).

2. Two rubber bands (in handmade bags).

3. A piece of 370 mm long and 80 mm wide calendar paper (or other similar paper) (bring your own).

4. A piece of single-layer blown paper or thin cardboard with a length of 120 mm and a width of 40 mm (bring your own).

Second, the production process:

1. Talk about the introduction:

The aircraft model of the annular wing has a novel style, high mechanical strength, good flight effect and easy to make. Now, using the matching materials, we make a model airplane with ring-shaped wings by ourselves.

2. Demonstration production: (multi-** physical display table to show the teacher's demonstration production process).

Figure 1 of the textbook makes the parts diagram of the annular wing model airplane, and Figure 2 is its assembly diagram and molding diagram, and students can listen to the teacher's explanation while reading the illustrations in the textbook.

1) Cut out the calendar paper (or other similar paper) in Figure 1 of the textbook, and glue the two ends A to each other to form a annular wing.

2) Cut and process the single-layer blown paper (or thin cardboard) according to Figure 1 to make horizontal wings and vertical wings.

3) Fuselage production: Take a 250 mm long paulownia strip, according to the shape and size shown in Figure 1, first draw the outline of the fuselage on the paulownia strip, and then use a sharp knife to cut off the excess part.

4) Whole aircraft assembly: first glue the horizontal tail to the plane at the end of the fuselage. When bonding, pay attention to the symmetry of the horizontal tail left and right, and keep it vertical with the side of the fuselage. Once the vertical tail is firmly attached, the wing can be attached.

5) Clamp the wing to the fuselage with a paulownia strip about 90 mm long, tie the paulownia strip firmly with the fuselage with a rubber band, (you can refer to the textbook assembly drawing) point A at the wing bonding point coincides with the wing centerline, so that the rings on the left and right sides of the wing are equal in size and shape. In order to make the wing have a stable upper and reverse angle, after the rubber band is fixed on the wing, apply a little glue on both sides of the paulownia strip, and glue the root of the upper wing surface and the side of the paulownia strip to each other.

6) Test flight adjustment: After the model aircraft is thrown, the attitude of the aircraft shows the nose planting, which is the reason why the nose is too heavy, and the wings can be moved appropriately in the direction of the nose. If the trajectory of the aircraft is wave-like, the nose is too light to move the wings back.

If the trajectory of the aircraft is not straight and it always circles and flies, then you can check whether the left and right shapes of the wings are consistent and adjust them; Or adjust the flight course by adjusting the rudder (vertical tail).

You have to have the drawings, and then you have to start working on them to scale, and then you can adjust them when you're done.

Do you want a scaled-down model of plastic? Or a paper model?

The first step is the overall design.

1. Determine the airfoil.

We need to choose different airfoils according to the different uses of model aircraft. There are many airfoil types, thousands of them. But to sum up.

In the future, the airfoil type of the aircraft is roughly divided into three types. One is the plano-convex airfoil, which is characterized by high lift, especially at low speed.

Row. However, the drag is modest, and it is not very suitable for inverted flights. This airfoil is mainly used in practice aircraft and real aircraft. The second is.

Double-convex airfoil. Among them, the biconvex symmetrical airfoil is characterized by the fact that it generates lift at a certain angle of attack, and does not produce lift at a zero angle of attack.

The nose pitch of the aircraft does not change much during forward and arrival flight. This airfoil is mainly used in aerobatic aircraft. The third is the concave and convex wing.

Type. This airfoil has more lift, especially at slow speeds, and has better lift than other airfoils, but it also has more drag. This.

Airfoils are mainly used in gliders and special aircraft. In addition, the thickness of the wings is also particular. With the same airfoil, the thickness of the low-speed lift is large, but the drag is also large. Low-speed with small thickness has less lift, but less drag. In fact, as far as the selection of airfoil is concerned, it is a relatively complex and highly technical problem. The basic idea of determination is:

According to the flight altitude, wing chord, flight speed and other parameters to determine the required Reynolds number of the aircraft, and then according to the corresponding Reynolds number.

and your aircraft type to find the right airfoil. Also, many airfoils of real airplanes cannot be used directly in model airplanes, etc.

I won't go into detail here. The common shapes of wings are further divided into: rectangular wings, swept wings, delta wings, and spindle wings (elliptical wings). The rectangular wing has a simple structure and is easy to make, but it is heavy and suitable for low-speed flight. The swept wing has a gradient of 27 from the wing root to the wing tip

Remind you not to be greedy for cheap tools, after all, you get what you pay for, like a small setback; needle-nose clips; small hammers; You can go to a hardware store to buy screwdrivers and sell them everywhere.

Basically, the color needs to be an airbrush, in fact, the difference between domestic airbrushes is not big, you can buy a caliber, you can buy it for less than 200 yuan, and then it is an airbrush with an air pump, choose a special model, about 400 yuan. This is the most expensive tool in the model, take good care, you can use it for a lifetime, so the airbrush and air pump are not expensive, hehe.

After buying an airbrush, of course, there must be corresponding model paint and model solvent to dilute the paint and clean the airbrush, and the method will be slowly explored, and finally your model level will go up a notch.

Then there is a small part of the face brush, I recommend you to the art supply store to buy a set of nylon hook pen and a tube of face brush, after all, the details can not be sprayed with an airbrush, the face pen is not cheap, I recommend you to buy Tian Gong (10-20 yuan have, for the model is special, much stronger than the general face brush).

Finally, the fighter model must be bleeding into the line, otherwise it will look like a toy.

Bleeding line: The common method is to dilute the oil paint with oil paint and ZIPPO lighter oil, or add Tiangong oily solvent with Tamiya enamel paint, and apply it to the tank weld, aircraft groove, screw, etc. with a brush to make the color seep into it, and after the seepage line is completely full, wipe off the excess paint with a clean cotton swab to achieve the effect of strengthening the shadow of these parts. (A bottle of lighter oil 133ml, 25 yuan, you must buy the real one, otherwise the fake contains alcohol, which will hurt the paint).

Oil paint is very cheap, about five yuan

Hello, the production process of model airplanes2021-02-10 02:12:141, main tools:

Model airplane KT board, destroyed aircraft wings, tail, fuselage, engines, landing gear, control system. Auxiliary tools: utility knife, heat capacitance glue gun, scissors, pliers, screwdriver, scotch tape, electric drill, fiber tape, velcro.

2. Take out the aircraft model module 3, connect the two pieces of the vertical nose center plate 4 on the foam template, cut the slope degree of the auxiliary Ji and the tail Ji, and connect it with the main Ji with fiber tape. Install fixed servo reinforcing plates. 5. Install the servo and tie rod, and the rudder angle on the servo must be vertical.

The screw adjuster can be installed on the rudder angle first, fixed with 502 glue, and the rudder angle on the servo is installed first and then installed on the main ji) 6. The carbon rod of the fuselage is connected with fiber tape, and the center plate of the vertical head and the motor are installed, and the angle of the motor is adjusted. 7. Install the receiver and electronic regulator for short, and connect the rudder electrical cable plug with the receiver.

Airplane models can do this:1. First of all, we cut the long paper strip into three sections, one of which is a little longer, and the rest are cut a little shorter, and then cut out a hard paper strip on the waste paper box, and finally prepare some thin paper strips one by one.

2. Next, put the strip of paper on the table, put the bamboo skewer in the middle of the strip of paper, and fix the bamboo skewer and the strip of paper with a thin strip of paper and a solid glue ballast.

3. Then take out a small piece of hard paper, fold it into the shape of an aircraft tail, and fix it with solid glue.

4. Finally, the tail wing is mounted on a bamboo skewer, and then fixed with thin paper strips and solid glue, otherwise the tail wing is easy to fall off. In order to make the aircraft model stronger, we can also use thin strips of paper to coat solid glue, and then wrap it around a bamboo skewer to stabilize the wings and tail, so that a simple model for you is completed.
