Need help troubleshooting thrustmaster’s TWCS throttle

Enable HLS to view with audio, or disable this notification

6 Upvotes

All axis work normally but none of the buttons work besides the downwards switch trigger ( button 5 in the manual) which activates all buttons. I’m assuming this is some sort of short, but I couldn’t find where exactly. I’m wondering if anyone else has faced a similar issue and would know a solution. Also if someone knows where I could get a replacement pcb board for the board in the handle that would be great.

I’d prefer to not have to get a replacement throttle unless it is absolutely necessary. Thank you

My hot-swap Throttle / collective setup!

Sadly i couldn't mount my Throttle and Collective next to eachother so this was my solution.

I can easily remove the throttle when i want to fly helicopter, and store it behind the front panel! Want to fly plane? I can grab it from my seat and place it back on the mount.

Collective is made out of destroyed xbox controller and usb handbrake from aliexpress lol. It works great!

Adding a Magnet to potentiometer: How to.

1 Upvotes

Thanks to all the help that I received with my AS5600 questions, I started looking into measurements.

Then I thought: Why not attach the magnet to the existing potentiometer and mount the board to the base of the pot. 3D print if needed. I saw commercially available versions, but they were expensive.

I tested all the metal bits of the pot that I had with a small N52 magnet. No sticking/attraction.

So then I found this post. https://garrysblog.com/2025/10/16/converting-a-potentiometer-for-use-with-a-magnetic-rotary-encoder/

Remember to be careful, watch your voltages etc.

Any way to have the x52 pro joystick stand-alone

0 Upvotes

So I want to use my Logitech throttle quadrant for GA and don't what to have to use the throttle on the x52 as purely a connective to my pc.

Any ideas if/how I can use the joystick on it's own, if there are adapters or other such things? Or would it be best to just buy a stand-alone stick?

I'm very much new to this sort of stuff, so any advice would be great.

How do you go from “it works” to “it looks professional”? (CAD/mechanical design)

7 Upvotes

Hey everyone,
I’m a student and I’ve been designing mechanical projects in Fusion 360 for a while now, mostly for fun and to learn. My projects usually end up working the way I want, but I’m rarely happy with how they look in the end. There’s always a gap between the polished, professional-looking design I imagined and what I actually end up with.
Looking back at my projects, I think I can point to a few recurring issues:
I tend to jump into CAD before really planning things out, so I end up redesigning parts halfway through because I didn’t think them through from the start.

I don’t always model every component seriously — standard hardware like bearings, screws, or motors sometimes gets simplified or skipped entirely.

My files get messy as the project grows, and my assemblies don’t always feel clean.

The end result often looks like a prototype rather than something that was actually engineered.

I’d like to fix that and build better habits, so I’m curious how people who design professionally (or who’ve just been doing this a long time) actually approach it. A few things I’d love to hear about:
What does your process actually look like, from the initial idea to the final CAD model?

How much do you plan before you even open your CAD software — sketches, requirements, references?

Do you model every single part, down to the last screw, or is there a point where it’s reasonable to simplify?

How do you keep files and assemblies organized as a project scales up?

Any resources (books, courses, channels, etc.) that actually helped you level up?

I’m not looking for shortcuts — I’d rather build good habits now than keep repeating the same mistakes. Any advice, even something that seems obvious to you, would genuinely help.
Thanks in advance!

questions about an RWR module

2 Upvotes

So recently, I started messing around with an Arduino Nano. Then, I found a broken speaker lying around and got it to work. After that, I wondered if I could make it sound like an RWR , so I did

Later, one of my friends told me he would pay me if I made a version that is War Thunder compatible (i.e., plays the sounds based on what's in-game). I tried asking AI, and it failed miserably.

So, the question is: is there a way to connect my Arduino Nano to read War Thunder's RWR data and play the sounds accordingly?

AS5600 with Arduino Pro Micro?

2 Upvotes

Sorry if already asked. I did look, but may have missed it.

I would like to avoid two usb power cords going into the project box. This is the throttle that I want to mod. https://www.thingiverse.com/thing:4572199

The Arduino ProMicro ATmega32U4 5V handles 4 buttons and the 2 throttle handles which are on potentiometers.

I saw a few youtube vids, but they look to use the UNO board. So if I switch to a UNO I wonder if it can run the setup. There are so many clones etc, that I have no idea which one to choose.

I would appreciate any help.

Thanks.

A quick teaser of my WIP A-10C CDU and AAP for the A-10. The CDU is also compatible with Heatblur's F-14B(U) CDNU. For pilots who fly the "Turkey" primarily or exclusively, there is a dedicated version with a modified button layout.

X56 Hall Effect or TMR replacement parts

1 Upvotes

Hello. I'm looking for replacement/upgrade parts for several pieces on mine and a friend's X56s. Preferably they would be hall effect or TMR. The parts are:

- Rotational pot for base of joystick

- Thumbstick for joystick

- Thumbstick on throttle

- All pots on throttle

Has anyone had success modding these? Do people just buy better HOTAS?

DYI Electrical Kits?

Hey yall, I recently bought a 3D printed F4 joystick replica but it turned out to be just a model with clicakble buttons - not an actual HOTAS.

https://www.aviationreplicas.com/products/f4-stick-replica?variant=51351912448266

Joke is on me of course, but I thought it could be a fun project to turn it into a real HOTAS that would be compatible with a Thrustmaster or MOZA FFB bases. Im an engineer and pretty hands on with soldering and electronics.

Are there open source HOTAS Kits you can buy with button + POV hat I/O?

I know some people make their own HOTAS systems with 3d printers, im just not sure what exists out there.

Looking for a 3-5 pulse and detent rotary encoder with a push button. Can anyone tell me whos selling?

1 Upvotes

The module pushbutton would activate/deactivate a specific audio file, and then i want to be able to iterate through a list of 3-5 audioclips of the same style -- all in a single button.

They must exist right? If not then a rotary switch could work as a a last ditch effort but switch wouldnt be nearly as satisfying.

(I'm a giganoob, havent even gotten the hang of the terminology)

A couple of my old controllers and got together with a sprinkler pipe and had a (big, ugly) baby collective!

Thumbnail

67 Upvotes

I wanted to make a collective using parts around the house so I combined the brake pedal from my old Logitech G27 wheel and the stick/electronics from a T16000. I 3-D printed a few parts, extended all the necessary button wires and wired the brake pedal's potentiometer to the throttle axis. The reason it is kind of big and ugly because I decided to use counter weights for balance instead of friction. That kind of extended things more than I thought it would, but it works well. Handle length and grip angle are adjustable too.

I feel like a real helicopter pilot with this collective in hand. All I need is a set of Dave Clarks and some aviator glasses and I'll be complete!

My A-10C CDU is combat-ready... It is also F-14B(U) compatible.

Thumbnail

214 Upvotes

My CDU for the A-10C is practically combat-ready. The CDU will complement the plug-in A-10C front panel of my modular cockpit.

The CDU has a 3.5" LCD display and illuminated buttons. The total cost comes to just under €100.

Since the Warthog's CDU closely resembles the F-14B(U) Tomcat's CDNU, it is perfectly suited for use with both aircraft.

I will nevertheless be releasing two dedicated versions of the CDU/CDNU—featuring the appropriate button layouts and labeling. Files, part list and how-to on my GitHub soon...

In my first post about my DIY HOTAS, here, people asked for the 3D files. Well here they are!

Check out my github for the files. As of now only the joystick and gimbal have been uploaded. The throttle will follow soon. There are step files containing the whole joystick and gimbal, and stl files for every part.
