FW 190 - RC Airplane

Just like last devlog, I didn’t do too much exciting stuff.
I changed the attachment of the nose and inner parts-tray, so the nose is screwed to the main body, while the tray is just tucked in place.
I reprinted some parts and cleaned them up.
I cut the carbon tube that goes trough the wings and bent the springsteel wires for the front and back gear.
The picture just shows all the sketches I drew during the entire design process, which I just think looks cool.
See you on the next (and probably last) devlog =D

Since last devlog, I didn’t do much exciting stuff.
I spent hours trying to solder everything, only to find out that the soldering irons tip was the problem all along.
I cleaned up, tested tolerances on the printed parts, made small changes to the model and reprinted some parts so they would fit.
Not very interesting, but it brings the project forward.

Finally, after so much time, all the parts are there. I still need to solder some things and make sure everything fits nicely, but after that, the final assembly may begin : D

Hey guys, I am finally printing all the planes parts now! I‘m printing with ASA Aero which was an absolute nightmare before having the right settings, with strings everywhere and many failed prints. But now the settings work and the prints look great for the filament. Probably only one more devlog before shipping this project XD. See you on the next one.

Welcome to devlog number 8.
Most I did, was to design some gears for the back steering-mechanism.
It now consists of one twirly gear on a small motor I took out of a servo, which slowly turns a chain of gears.
I also made some small additions, mainly to stabilise the structural integrity after putting the different printed parts together.

Welcome to my 7th devlog.
Since the last devlog, I have worked on fixations for the cockpit, the back wheel, some irl hardware stuff and the steering mechanisms in the back of the plane.
As it turns out, there is so little room in the back of the plane, that I could not fit a servo in there to deliver the needed form of motion. Because of that, I had to deconstruct a servo irl, so I can measure and fit the single parts (potentiometer, motor and the pcb) where I want them to be, kinda like a custom servo-version.
The cockpit now has little springs in the back and some kind of nose in the front for a quick montage and removal.
I also replaced the voltage step-down converter of the little electronics complex for reading and sending the controllers data I use to control the plane, because the old one wasn’t working. Sadly, it seems like the esp32 I was using to read the data, now has a short-circuit and completely overheats after a short time.
Next I will integrate the core servo parts of the servo I demolished into Fusion 360 and hopefully make it work. And buy a new esp32 :(

See you on the next devlog :)

I’m finally back to working on my project!
The last days, I mostly worked on the internal arrangement of all the necessary parts like pcb, battery, servos etc.
The mechanism for controlling the aileron/flaps now consists of two gears on top of each other at a 90° angle, so the servos wouldn’t have to be in the middle of the plane, creating a space problem.
I put the battery, pcb and ESC controller onto a removable tray, so taking the battery out is easier.
The tray will be fixed with screws in the back, and be connected to the removable front part of the plane for a semi-easy removal while also holding in place while flying.
I also fixed a real-world issue with the gear, where in CAD it would fit perfectly, while being out of place irl.
Now the only ramaining thing to do is to design the mechanism to steer the rudder, which is quite tricky, because there is pretty much no space at all to attach anything in the very back of the plane.
See you on the next devlog :)

Hello guys, I am finally finished with the pcb design.
Now all that is left to do is to finish the steering mechanism in the plane, adding a mount for the pcb and then assembling everything.
Sadly I wont be able to work on this project for about a month or so, since im on vacation.
See you on the next one!

Hey guys, this devlog I just fixed some problems with the 3D model of the aircraft and added a screw mount for the cockpit, so it holds onto the main body and is detachable.
I also started to do some research on electronics and pcb design for a simple main pcb in the plane.
I even started with the schematic but still have quite a lot to learn and do.

Hi guys, it has been quite some time since my last devlog in which I promised to show the plane model.
Now I am almost finished with it. Because this was my first time modeling something as complex and dynamic, it took me much time to figure things out.
I also did the first test 3D print which pointed out some important issues I will need to fix.
Heres a quick overview of how I intend the aircraft to function:
-The main body will consist of multiple parts which get put together with glue
-The wings will further be stabilised by a carbon pipe
-It will have retractable gear
-The flaps will be controlled by spinning rods connected to gears inside the main body
-Everything will be connected to a main pcb and controlled by an esp32 which receives the data via an antenna

See you on the next devlog!

Hello guys, this is my second devlog on my RC airplane. I’m finally finished with programming both the receiving and transmitting ESP32 boards which I use for this project.
Heres a list of all the things I did/added and fixed since the last devlog:
-I got the antennas working
-The radio connection works and transmits the data I want
-The receiving ESP32 now hands the signals down to servos
-Fixed a problem with the servo library where attaching the servos to any pin would overwrite other attached servos
-Added an easy kind of failsafe
-Built a container for the electronics that goes on the back of my controller on the transmitting end–> still working on it but almost finished
I will update you guys, when I have a decent 3D model of the plane to show.

This is my first ever devlog so don‘t expect too much. Heres what I already did:   -I set up my coding workspace -I connected the ESP32 to my controller and can read the data -I set up the Antennas and tested them Now I just need the Antennas to work together with the rest. After that I will start to design the plane in CAD. Thats it for the devlog, I‘ll post the next one, when i‘m finished with the main coding part.
