In this tutorial I will show you just how I construct an Arduino based RC Airplane, as well as also, I will certainly show you how to manage it making use of the custom build Arduino transmitter that I constructed in among my previous video clips.

Summary

So, the airplane is totally made out of Styrofoam. For making the forms I used my Arduino CNC Foam Cutting Machine which I currently revealed you just how I constructed it in a previous video clip. Although I'm making use of a CNC equipment for developing this Arduino RC airplane, I can still claim it's 100% DIY since the CNC machine is additionally a DIY build.

In https://electricrctoys.co.uk/product-category/rc-vehicles/rc-vehicles-rc-boat/ , the control of the plane is likewise 100% DIY, based upon Arduino and the NRF24L01 module for the radio communication.

Making RC Boat of the ideal joystick of the transmitter, we can control the ailerons as well as the elevator of the aircraft, and utilizing the left joystick we can manage the rudder and also the throttle. In addition to that, using the right potentiometer we can adjust the controls responsiveness, or minimize the amount of servo travel, as well as utilizing the left joystick we can sub-trim the rudder or adjust the neutral placement of the servo arm.

Oh, as well as I virtually forgot the reference, the highlight of this Arduino RC airplane is flying, so yes, it can fly.

Designing the RC Airplane-- 3D Model

I began by designing the aircraft making use of a 3D modeling software, Fusion 360 in this situation. I made the style by considering some industrial RC airplanes as well as adhering to some basic guidelines or general rule for version aircraft parameters.

The starting point is the wingspan, as well as I picked to be 80cm. From there we get the fuselage size, which is usually 75% of the wingspan. When it comes to the airfoil, or the wing sample I picked the CLARK Y Airfoil, which a preferred option for RC airplanes.

I downloaded and install the airfoil form from airfoiltools as.SVG file and after that I imported it right into Fusion 360. I changed the dimension suitably, so that the wing chord, or the size of the fly stream-wise direction is around 1/5th of the wingspan.

The straight as well as the vertical stabilizer are likewise sized according to those fundamental guidelines. Below are some those basic RC model aircraft style specifications:

The body of the aircraft will be constructed of 2 10mm sides and a 50mm core which will certainly be hollow to accommodate the electronics.

You can download the 3D version from the links over. There are 2 version of the Airplane. The variation 1 is the one shown here in the photos, as well as variation two has a bit smaller nose and the motor can be positioned a lot more to the front in order to boost air movement.

Getting G-codes for my DIY CNC Foam Cutter

Now, as my Arduino CNC Foam Cutting Machine work area is limited to 45cm, and the body is 60cm in length, I had to make the fuselage out two parts.

So, I cut the fuselage at 34cm from the front point, and also made a new illustration in which I projected the shape and also included a factor near it. Next off, in the manufacturing tab of Fusion 360, I can generate the G-code for reducing the forms.

Here, initial I made a new configuration where I picked the illustration as a design, chose the point I added earlier as origin for the configuration, and also adjusted the X as well as Y axis suitably.

After that I chose the 2D shape procedure and also selected or created a brand-new device, with diameter of 3mm, because that's the approximate dimension of the cuts that the hot wire makes when passing through the Styrofoam. Below we can also set the reducing feedrate which relies on the hot wire itself and also the firmness of the Styrofoam. I set it to 150 mm/m.

Then in the geometry faucet we can select the shape or the form that requires to be reduced. As for the elevations I established them all to 1mm as there isn't any type of Z axis activity on my foam cutter maker. Finally in the Linking faucet I picked the entry setting to be the side situated near the beginning factor.

With this the toolpath is generated and also we can take a look at it by clicking the Simulation button. The toolpath should be a closed loop solitary pass, as well as if that's the case, we can lastly create the G-code. For that we can go to Post Processes, choose the GRBL firmware, select the output folder, name the documents as well as click the article button.

Then we can conserve the file, and we can see the G-code in the WordPad editor or something similar. So now once we have the G-code file, we can fill it into the Universal G-code sender and send out the G-code to the CNC maker to make the shape. We can keep in mind that the process that I've simply showed you is most likely not the best one or not expert at all, yet still it does the job for obtaining the G-codes to collaborate with my DIY CNC Foam Cutting Machine.
