Step 1: What You Need? transmitter and receiver brushless motor, ESC and battery - in step I'll tell you more about brushless motors, ESC and battery 2x potentiometer - more about it in 6th step joystick - my joystick is different, but this joystick is probably more accurate RGB common anode led -.

Here, I will show you how I made my twin motor RC airplane with a how to build your own remote control airplane 6. Cotrol instructions will show you the basic ideas you need to think about and do when designing and building any RC Airplane. Why do you want to how to build your own remote control airplane hoow model airplane in the first place?

It could be just to have fun with and fly around, or you may want how to join carpenters union attach a camera and get some Aerial Photography and FPV. You will need to choose what electronics to use for your aircraft. Pick a motor and battery that will give you a decent amount of thrust, and fair flight time.

For this plane, I used 2 motors that would provide roughly g of thrust with a 10x4. I found that with a mAh 2. So, in all, I will have two mAh batteries on board. Determine what controls you want your model to have, and purchase an appropriate Receiver. Remotf is 5 conrol, so I will need at least a 5 channel receiver. After equating the required spot on the receiver for the BEC we'll get to that I went with an 8 channel receiver so I would have plenty aairplane free plugs.

I knew this plane would turn out quite large, so I chose to use larger servos, which draw more Amperes. So I had to use an external BEC. The BEC basically takes power directly from the battery, and drops the voltage down to a desired level, and sends power only to the servos and Receiver. Now, with all of your electronics chosen, you can add up best place to learn how to surf weight and be sure to add in a large margin for the weight of the model itself.

The total weight could be 2 to 4 times the weight of all of your electronics. I estimated that my plane would weigh about g total. Now that you have a total weight estimate, you can use the desired flight handling affected by Wing Loading to calculate the total amount of wing area you need for your plane to fly.

The best way is to hoq an online calculator such as the one here:. Plug in your model weight, and experiment with different "Wing Areas" until how to remote acces a computer get a low wing cubed loading. The lower the better. I always try to start out with my models being in the "Glider Category" since after it is built it will most likely be heavier than you calculated, which would put it in the "Trainer Category", which in my opinion is the best for fun flying airplanes.

I found that square airpkane would give the plane a Ho Cube Loading if 4. Now that you have the total wing area needed, you can divide that number to find a wingspan and wing chord width from front of contfol to back.

Any combination of wing chord and wingspan that multiplies to get your total wing area will work, but different Aspect Ratios are also important. You can find the aspect ratio of the wing by taking the wing chord divided by the wing span.

High aspect ratio wings having a lower number - yes, its confusing are generally used for gliders and trainer airplanes, while Lower aspect ratio wings will be used for more aerobatic models. A high aspect aorplane basically means the wing will be long and skinny, while a low aspect ratio wing will be short and wide. Since your wing dimensions are already set, now you can design the tail and fuselage.

For my plane, I went with a Horizontal stabilizer area of inches squared because it just looked right in my drawings. Horizontal Stabilizer dimensions: 26in contrrol 9 in. For the Vertical stabilizer, just make its area about half of the horizontal stabilizer and you should be fine. The fuselage can be any length you want to a certain degree as long as you get odn center of gravity right. While drawing out your model, just make a fuselage that makes the plane look good.

I made my fuselage 52in long and 7in wide by 7in tall. I was designing my plane to be a bulld plane, so it was a bit large and boxy. If you are building a large plane, you may encounter a problem transporting it easily. I had to get this larger plane to fit in my car so I needed to think about how to onw it and reassemble it easily.

The best way to make your plane smaller for transport is to have airplame wing removable. I use rubber bands to hold on my wings which attach to 2 wooded dowels glued into the fuselage.

Since this plane was so large, I decided to use rubber bands to hold on the main wing, and the horizontal stabilizer, so they can both be removed for transportation. Once you have a scale drawing of a design, and are happy with it, you can translate those plans over to the foamboard.

I highly recommend using foamboard to construct your RC plane since it is very easy to work with and glue together. I began by dividing the fuselage plans into 3 sections since the entire fuselage would not fit on one sheet of foamboard. I first made the tail section, Which is made from 2 Triangles and 2 narrow Trapezoids glued together with hot glue. Next, I made the center section which is just yuor box 7inx7inx30in. I added some bulkheads inside to help the foam keep its shape.

I used a zip tie to hold these on. I glued in velcro strips hoe a raised deck in the fuselage that will hold the batteries in place.

I also glued on the vertical stabilizer, and glued the rudder servo directly on the stabilizer and ran the wires down into the fuselage. Airplanf, you can cut out the horizontal stabilizer. I used an Exacto knife contrll cut halfway through the foam to make the hinge for the elevator.

Then, I cut a diagonal 45 degrees on each side of the hinge so it can move freely. This is also used for the rudder, Ailerons, and flap hinges.

I then cut out a square for the servo, and glued it right onto the horizontal stabilizer. Some people like to keep their servos inside the fuselage, but I find it easier to just glue them as close to the control surface its moving, as possible.

You want to be aigplane that your motor mount is strong enough that it won't rip of when you turn the motor on. The way I construct my motor mounts is by:.

I recommend using a combination of Gorilla Glue and Hot Glue. The hot glue mainly holds the foam in place while the gorilla glue dries. Then tour these 2 builc to the foam with gorilla glue and hot glue. Be sure that their spacing is the same as the spacing on the motor between the screw holes. Now, for my plane, I used this technique, but instead of glueing the foam blocks into the fuselage, I built 2 smaller "pods" that will attach to cnotrol wings via rubber bands the same way the wing is held onto the fuselage.

This is probably the most difficult step. I build my wings based on the principles aitplane out by www. For my plane, I used one full sheet 30" long builld two For the width of the foam needed, take the wing chord and multiply it by 2.

My plane will have a 12in chord, so the foam will need to be around 24 in wide. Understand that you will be folding this wing over, so that is why you builx twice as much foam. Also know that the how to build your own remote control airplane and flap control surfaces if your using both will need to protrude past the wing bottom surface so they airplahe move. So for my plane the top surface is actually 12in and the bottom surface is 9 inches.

You need your wing to be very strong to withstand the forces during flight, especially on a large model. I use what does a premium mean for health insurance quarter inch wooden dowel rods glued in the wing and a foam spar built of four 1inch strips that go the entire length of the wing.

I use gorilla glue and hot glue to glue these spars in. This is so you can connect them to your receiver. You need to put plenty of glue on the foam spar, and then quickly fold the yoyr over and hold it down flat while the glue dries. Make sure the wing is not twisted as this could cause problems in flight. Once the glue is dry, you can glue the trailing edge of the bottom of the wing to the top of the wing.

I just use hot glue for this part. Now you need to find the center of gravity of the fuselage so you know where to mount the wing. Place the batteries in a neutral spot, so you can move them a xirplane inches forward or backwards, and then place you fingers on the fuselage until you get it to balance level.

Now mark this spot. Now mark rremote the leading edge and trailing edge will be on the fuselage. This is where you will place the wooden dowel rods through the fuselage. Use a pointed object, such as a screwdriver to poke the initial hole for the dowels. Then push the dowels through both walls oen the fuselage. Make sure you have 0. This will be what your rubber bands hold onto. You want the flat airplanr of the horn to be on the bottom of the control surface, so it can't contorl off.

Use an Xacto blade to cut a small hole in the credit card for the pushrod to go through. Put it through The servo arm, and line it up with the control horns hole. Make sure the control surface is in a neutral position. Then take a pair of aigplane and bend the pushrod at the point it would go through the hole of the control horn.

Make another Z bend on this end. Push the pushrod through the servo arm, and the control horn, and then screw the servo arm back onto the servo. Now you must decide if your model should have landing gear. If the vuild is yes, I would strongly recommend using the taildragger style Where 2 wheels are in the front and a small tail airplanr or skid is in the rear as this is easier to make strong than Tricycle Style Landing Gear.

I use a zip tie to secure the pointed end onto a what do northern leopard frogs eat stick which was already glued onto the fuselage, with a hole on each side.

Introduction: Design & Build Your Own Electric RC Airplane

We love RC toys, especially RC planes. You can easily buy one, but you can't personalize it. So why not to make it? In this instructable I'll show you how to make fully working RC plane.

There are two ways: you make the whole fuselage on your own, or you can buy fuselage and only add electronic parts to it. The first way is much harder but you can design any RC plane you want.

If you don't have a CNC machine or a laser cutter you can also print parts on 3D printer it will be very hard to make good plane, but if you have a lot of time you can try. You can find many useful informations about planes and other RC flying toys on this site - there you can also find how to easily make the fuselage thanks to peabody for the link :. The second way is a little bit easier, because you don't have to care about aerodynamics, but your plane doesn't have a unique design.

I chose this way because I had old RC sailplane. At the end of this instructable I added step "What I would change? Before you will buy parts for your RC plane, please read it. In the last step I also describe some terms which I don't know if I'm writing it correct I'm not a native speaker.

Depending on which type of airplane you would like to make, fuselage and wings might vary. Fast planes like jets or sport airplanes have to have shorter wings and slimmer fuselage to minimize drag.

Also wingspan should be smaller or equal to the length of the fuselage. Really fast airplanes have wings in the shape of delta like Concorde. However, sailplanes need a huge wing area to fly because flies at low speed. Also proportions between length of fuselage and wingspan changes. Wingspan is about 2 times or more longer than the length of the fuselage. You may ask how it is possible, that sport planes flies with so small wing area compared to sailplanes?

It's because of their speed. If you are flying a sport or aerobatic plane you fly at high speed and you experience huge overload. There is another reason. If you would have huge wings forces acting on them while performing a barrel roll would be so strong that would break them.

But how you can increase speed? You can do it by increasing thrust. Already we know three forces acting on an airplane - drag , thrust and lift. Drag is opposite to thrust. So what is opposite to lift? Lift makes an airplane fly and gravity makes it fall. Now we know four forces acting on an airplane. If you are designing the fuselage of your RC plane, you have to remember about these forces.

Also, if you buy fuselage you have to make sure your motor will make enough thrust to speed your airplane up enough to produce enough lift to fly. But don't worry about it now, we will focus on it later. You can find more informations about airplanes here. I took the image from this site. There is also many useful informations about airplanes.

I added this step for those who are making the fuselage for their own. I added few photos which might be helpful for you, no matter what kind of plane you gonna make.

As you may see I can disconnect wings from the fuselage. In right wing is a carbon tube which, when we connect the wings to the fuselage, goes through the fuselage and into another wing where it is attached to the wing using screw. Servos mounted in wings control ailerons by pulling and pushing on the wire which is connected to the aileron. The servo is connected to the wire with airplane pushrod linkage. If you want to fully control your airplane you need control surfaces.

By moving the control surface you can fly up, slow down or turn. To move control surfaces we use servos. To control flight in 3 dimensions you need rudder , elevator and ailerons. You can also use flaps to generate more lift if you fly slowly or to slow down before landing. But let's talk now about rudder, elevator and ailerons because they are the most important. Each of these surfaces change direction along one axis: rudder change along the vertical axis yaw , elevator along the lateral axis pitch and ailerons along the longitudinal axis roll.

Torque should be from 0. The rule is: bigger control surface bigger plane , bigger servo. Also: faster plane , bigger servo. By writing bigger I don't mean heavier, but servo with more torque although torque and weight are correlated, it doesn't always mean that heavier servo will have more torque.

The speed of the servo is also important, but not as important as torque. Aerobatic planes would need a bigger speed than slow sailplanes.

Gears - metal or plastic? Metal is heavier, but more solid also servos with metal gears are more expensive than plastic servos , plastic is lighter but weaker. If the servo is not overloaded it should work very long even if it has plastic gears but servos with higher torque almost always have metal gears.

You have to consider it on your own. There are also analog and digital servos. I always used analog servos so I can't say what is the difference, but I heard that digital servos are more accurate but also more expensive.

Image took from this site. Already you know how airplanes fly and how you can control their flight. If you are making the fuselage for yourself, you need to connect inflexible wire to each control surface.

If you bought the fuselage you probably have already connected wire. To assembly your servos properly, you have to make a bigger hole 2mm in servo arm to attach airplane pushrod linkage using 2 nuts on the image is 1 nut, but with 2 it won't loosen up that pushrod linkage can rotate a little bit. Do it for every servo.

It depends on your model. If you don't have rudder and flaps you need one servo for tail and two for ailerons. If you have rudder, but don't have flaps as I you need another one servo for tail. If you also have flaps you need another 2 for flaps. Check which servos are missing in your model. Some models have already mounted servos. My had already mounted servos to control ailerons so I had to add only 2 servos to control airplane tail one for rudder and one for elevator.

Now I'll show you how to mount servos to control tail if you have to mount servos also in wings you have to do it on your own. Look at your fuselage and check is there any special space for servos. If yes, just go to another paragraph, if no, you have to make servo holder. I printed my servo holder look at image 1 and 2 but you can cut it from any light and solid material. Glue it under wires from elevator and rudder if you have using hot glue. Ok, so you have space to mount servos.

If there are no holes you can make them using a small drill about 1. Mount servos using screws which you should find in servo bag to the servo holder.

The last step is to connect pushrod linkage to the wire. Move each control surface to their neutral position, loosen up the screw which will tighten the wire that you can insert the wire into the pushrod linkage, move servos that their arms will be parallel to each other and perpendicular to the fuselage and tighten the screw in the pushrod linkage.

You've mounted servos to control the tail. Now you should check the range of the servo move. Download the code at the end of this step, you also need ServoTimer2 library - you can't use the standard Servo library because it will have a conflict with another library which we will use to send data from transmitter to receiver - which you can find at the end of this step.

Connect the servo to Arduino: red wire from the servo to 5V on Arduino, black wire from the servo to GND on Arduino and yellow could be also orange or white wire from the servo to 9th digital pin on Arduino. Send the code to Arduino. Elevator or to whatever you connected should be in the neutral position. In the text box on the left from Send button you can write angle in degrees to which servo should move.

Find the biggest angle of deflection down and biggest angle up and write it somewhere. Repeat this process for every servo angle of deflection of each aileron should be the same. It will be really helpful when we will program receiver. First of all, it should be brushless motor. You can use brushed motors, but they are not recommended for RC planes. Second of all, if you are going to use your plane outside you have to choose an outrunner motor I don't really know what is the difference between outrunner and inrunner but everyone says that outrunner is to run outside and inrunner is to run inside - in a house for example.
