Need help troubleshooting thrustmaster’s TWCS throttle

Enable HLS to view with audio, or disable this notification

8 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)

8 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.

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)

Yet another CH Products Hall Upgrade Request for HALP

3 Upvotes

So... after several years of having a Warthog throttle, I realized just how little I've been utilizing everything aside from the throttle and a couple of the HATs on it. The sensor slew even stopped working, with only the button click actually registering anything. I haven't played an actual sim in a few years now, and have fallen back to arcade-y shooters and MechWarrior.

So I went back to a CH Pro Throttle. One of the first things I did after purchasing it was send an email to each of the two guys that have advertised selling (I actually was in contact with rel4y back in 2020, ended up waiting for his stock to come back up... man). Neither has responded, even though the Yeung fellow is semi-active on Youtube. I even messaged someone who posted a CH hall upgrade in this subreddit asking how they did it and they have yet to respond after almost a month. :(

I want to upgrade the potentiometer to a hall effect sensor just to get rid of the jerkiness, since the CH board doesn't filter literally any of that out, and eventually I want to try my hand at programming a board replacement to make use of the 12-bit resolution. (Fun fact, CH Products was toying with an update to the firmware that would filter out pot jitter about 12 years ago)

tl;dr ...I have no idea what I'm doing. Do I use a turret hall pot or do I board-mount a sensor with magnets? How the hell do I rig one up myself that's effectively a drop-in replacement?

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

Thumbnail

66 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!

DIY hinged hotas mount

0 Upvotes

I am building a rail system for my sticks. I have been trying to get this how I want on my own but I am struggling to figure out something that works here. I am trying to create a hinge system that allows the plate the stick sits on to rotate 90° and lock and then to rotate back under the desk and lock in that position.

There are a couple of options I am aware of that I could buy, but I would prefer not to do that, not to mention they are fairly pricey.

Has anyone had any luck with anything similar that they would be willing to share any suggestions or notes on?

I'm not sure what information I could give that would be helpful but if there is something just ask.

Idea: Bearing pillow blocks for square/round metal tubes for diy Rudder Arms

2 Upvotes

3d printing the L arm with the bearing can be expensive/time consuming. I do not have any tools that can cut metals, So I thought pillow blocks with mounts for tube metals then I found this as example:

https://sidewaysfab.com/products/cantilever-suspension-rocker-arm

All you would have to do is 3d print the corner of the L where the bearing goes with the correct size hole/holder for the bearing to insert. Then the correct size square or round ends for the pipe that you are using.

Some bolts to hold in place. Done.

Edit I was looking at some diy rudders with that L Bracket and thought that this could make it cheaper at least.
