[@JD96893]

after paying 150USD in importation taxes on a 150USD joystick im looking for a cheap alternative to complete my setup! This really is outstanding content, not only a great video but you even made cad files and code public... I just wish more people looking into buying a collective for a flight sim could reach this video or even buy this as a complete kit. Like you said, buying a collective is really expensive, especially when you live in a country where customs are basically legal robbers.

[@JoshuaPritt]

Now I want to start on my custom controls and cockpit for Mechwarrior Online. Awesome job!

[@michaeltyers7336]

I'm in the process of designing/building a helicopter collective too. I've decided to use Hall Sensors for the collective instead of an encoder, and using Atmel 328P with V-USB's USB implementation.

[@AkaSoggyBunz]

My two favorite things Arma3 and arduino !

[@gerryabbott]

Nice project. Nice for ARMA, but certainly has me thinking, of a solution for my DCS modules. Was wondering why you choose an encoder over a hall sensor for the main collective position?

[@gypsysoul1719]

In Flight Simulator FSX at least, the collective function can be simply the normal throttle input from a joystick vertical axis - any normal joystick can be used, and it seems to me this is the same basic function you created here. You added a number of buttons that can be pushed w/o having to remove your hand from the collective - that's a valuable addition to a simple joystick functionality. I'm impressed by all the design and fabrication you presented, plus the digital circuitry and programming needed. But really, it seems a case of overkill for just the collective lever. Any decent helicopter control set needs foot pedals. That should be your project. It's mainly a mechanical problem to keep it smoothly linear over a wide enough dynamic range for the simulator, and using only short range of leg motion. Additionally it might be programmed to have variable sensitivity so that the signal varies more rapidly the harder the pedal is pressed. I made my own pedals years ago using one analog potentiometer, some springs, a few hunks of wood and a switch, activated by toe press, for the brakes when landing fixed wing. It worked to allow the correct method of sideslip for crosswind landings in fixed wing simulations. At that time most controls were analog, so the pedals and the two analog joysticks were connected to the PC game port. When PC's went to USB, I just inserted an inexpensive parallel to USB convertor box. You can do better since you know all about digital controls and mechanical design.

[@randywashington2348]

Nice job, i am a beginner and would like to built the complete this project, where could I get the parts, software etc. thanks

[@element14presents]

[@sietflo_OG]

Why use an Encoder and not just a Potentiometer for the AXIS though ?

[@hotcols1171]

This is great - it is amazing what we can do today for integration, electronics off the shelf and a very small amount of work and then printing to join it all up! great stuff!

[@coastal9181]

You just gave me an idea. Buy 2nd joystick, mount at 90 degree angle by your left hand, map controls. You then have a collective with neutral position built in, a twist throttle, and hotas built in. Two Logitech 3d pro's would do it for $100.00 or less. Love what you did but I don't have a 3d printer.

[@blacksharkden8568]

Awesome project. Yes, collective for PC sims are ridiculously priced because it is a niche market. Thanks for this video. As much as Arma3 is an amazing infantry simulator and the graphics are awesome, it is at the level of a 1990 arcade game when it comes to fly helicopters. The only decent chopper sim on the market for PC is DCS. Also, IRL chopper pilots are always flying right seat. copilots are flying left seats.That's why, as you could see, the collective usually more simple on the left side as it is just meant for the copilot to take over the controls in case something happens to the pilot.

Blackshark Den, not all helicopter are commanded from the right seat, MD500 series (little bird) are commanded from the left seat. Cheers

[@God2glorify]

The reason the collective is on the left side is that, most of humanity is right handed and the pilots primary work load is the moving the cyclic with their right hand. All Helicopters have the collective on the left. And, if the copilot takes over, the copilot has her / his own cyclic controls as well as the anti-toque pedals, collective and throttle mounted on the twist grip of the collective. There is no way a copilot could control a helicopter from an opposite seat! I have been flying helis under the X-plane software for three years. I have a set of $3500 heli sim controls. My cyclic is partially not working and I was looking to replace its electronics. This is the reason I watched the this excellent video as it gave some hope that I might be able to come up with some electronics to replace my defective electronics in my cyclic control. My heli hardware manufacture has gone out of business. So I tried to buy a cyclic from Komodo Simulations that I found on the internet. It looks like they have an excellent design with many different cyclic models and configurations. I sent them $3500 the first week in February (22 weeks ago) and they never sent me my cyclic. So a word of warning - stay away from Komodo. (My credit card company is helping me get my money returned).

[@thibautmauron4758]

Awesome build! Nice job! Just one thing, helicopter collectives have also a throttle control (wrist rotation). Will try to work on your build and add a throttle control. Thanks !

[@wallstreetmemeers]

Have you thought about adding a twist grip? I know arma 3 would probably allow it too as you can switch flight modes to realistic or advanced controls.

[@coastal9181]

I think I solved the problem... You just gave me an idea. Buy 2nd joystick, mount at 90 degree angle by your left hand, map controls. You then have a collective with neutral position built in, a twist throttle, and hotas built in. Two Logitech 3d pro's would do it for $100.00 or less.

[@jesperkped]

You are missing the twisting handle on the collective for the throttle function (that's why the bought collectives are more expensive too)

[@cy-one]

But tbh, that's not really that much more difficult to include.

[@JamesW81]

@@cy-one I was thinking it should have a twist.... Hall effect sensor is the way to go on that, it could be installed in less than 30 minutes.

[@cy-one]

@@JamesW81 I'm currently planning on building a Teensy 4.0 based joystick, and it will have a "lockable" twist for the rudder (not everyone wants a twist-stick :D). I'll just use potentiometers for the analog inputs, though. I see no real advantage of hall effects in this case.

[@JamesW81]

@@cy-one I was just thinking HE for ease with the twist axis... Although saying that, I guess if you fit a pot in the end of the twist and fixed it to the tube somehow it wouldn't be much more difficult.

[@cy-one]

@@JamesW81 I disassembled an old Cyborg Evo today, and they had done more or less exactly that :D

[@gregpruitt1647]

Nicely done. Been looking at all of the store-bought solutions. What was the cost of this project?

[@AndrewDanne]

If you talk with a rotary-wing pilot, depending on the flight frame you will find that the collective has some load/weight and a level of haptic feedback. It can feel heavy at times and also light. You might think about adding this using servo motors and enabling the use of force feedback, relatively simple. It depends on the speed of directional motion, crosswinds etc.... If you didn't want to use servos then I suspect you could use a spring mechanism that has a lag in the tension release. Liked your work very much. Have fun.

[@kalebclark5826]

Thats a great idea! I am not sure about the feedback protocol coming from the sim. Do you have any experience with that part of it? I know how to do the hardware bit, but not familiar with the data stream coming from the sim software.

[@AndrewDanne]

​@@kalebclark5826 I am not familiar with the SIM and what it can provide. I use to work on real-world simulators. I suspect that there would be some math models around that would take in the rotational velocity & momentum, the rotary-wing angle of attack, frame airspeed velocity & wind skew, potentially torque control, and cyclic pitch would add to this. Airframe torsion would also play a factor. I am sure some of these instrument feeds are available from the SIM, but I don't think it needs to be that complex. Just simulating the heaviness of the airframe when you increase collective pitch and resistance when you decrease it. I suppose it needs to more closely represent the dampening of the collective. Additionally, when you hover there needs to be a feeling of weight in the collective. What I could say is.... get your arse in a real-world flight frame and experience it first hand what is needed, you will love it I am positive. There is a lot of feedback that the control systems provide. Then again its like cars, some have so removed you from the feeling of the road where other super high-performance cars need you to be able to feel the road, the steering the forces at play so as you can better anticipate your reactions.

[@KuraIthys]

That's also true of small GA/LSA aircraft that still use rod or cable coupling. The 'feedback' is the force of air over the control surfaces, so it varies with airspeed and several other factors. As for force feedback in commercial hobby simulators... I'm not sure. Historically we had the Microsoft Sidewinder and Logitech ranges of force feedback sticks, and it's possible some games may still support the underlying API's from those. But that means matching the design of your force feedback system to the expected behaviour of those old devices. It used to be part of DirectInput, but DirectInput is in itself technically semi-obsolete. (it's still in widespread use, but Microsoft keeps insisting people use Xinput instead. And X-input has some nice features, but it's also severely lacking in functionality compared to the older API...) I'd say it's anyone's guess if any flight sims still support the old hardware, and that's about the only standard we have. (that, and the Novint falcon, but I doubt you could reasonably replicate that - this is also defunct at this point. The Novint falcon is essentially a delta robot configuration repurposed to provide 3-axis force feedback... An interesting approach, but not the most straightforward. Plus compatibility might be difficult.)

[@bent6680]

There shouldn't be much feedback in the collective, and virtually none for an aircraft with hydraulic controls!

[@AndrewDanne]

@@bent6680 We tested this using dynamic load feedback systems for high reaction short and long-duration flights, additionally for low and high stress situations. No feedback = very unhappy pilots. Most pilots wanted to be able to feel the airframe through their hands but not the stress of airframe maneuvers & did not want the muscle load when on a long-distance flight. What worked was a system that allowed for adaption by the pilots. WIth the fly-by-wire (computer wire) these kinds of systems are readily implemented. Older guys who had flown the older airframes DC9's, Hueys, CH47's, etc.... had the ability to feel the flight frame through their hands and feet instead of just G's and instruments. Newer pilots because of re-action times were way more visual and instrument dependent and felt the flight frame more though body stresses. But what ever you come up with I am sure will add hugely to your enjoyment of the simulator. Cheers.

[@georgelza]

... be great if you can do something for the cyclic control also... pedals i'd say is easy, as there are many commercial options available at a reasonable price.

[@HarryLBorst]

[@duane8620]

That was awesome!! Been drooling over some teaser pics Virpil released this past fall and been dreaming of it since. As the video mentioned the market for these is just stupid pricing, most geared towards trainers rather than simmers. But between the homebrew market and hopefully some stick makers can get us what we want (without having to make it or sell an organ).

[@ellonysman]

Epic comment I approve! Lol

[@Andreas-gh6is]

I think an easier solution than a mechanically transmitted absolute encoder would be a VL6180X distance sensor measuring the arc distance. Might need something more powerful, like raspberry pico to smooth the results. Also: Raspberry pico allows programming joysticks with micropython...

[@otp_dagger3-366]

Great Video and nice project idea :) ... just one thing: ARMA3 is NOT a flight sim

[@andrewferraro8568]

You can use "1-position spring-back" switches bought as rc transmitter replacement parts. I found some on ali express when searching "transmitter switch". I haven't seen any 2-position ones though.

[@LazyBunnyKiera]

As someone wanting to build one of these, as soon as you mentioned 3D printed parts, my heart sank. I don't have, and can't afford a 3D printer. So i'd have to get the parts printed and mailed to me, which won't be cheap, or buy a 3D printer, which would cost the same as a premade collective. I was totally onboard and looking for all the mechanical parts until you mentioned those bits. :( Back to my own build i guess. I was just going to use a ~22mm dowel rod, as the collective rod. Why the 22mm dowel rod? So i can put an e-bike/electric scooter throttle on the end to control the helicopter's RPM. My biggest problem is the friction bit. I need a way to add the friction to keep it in place.

[@LarkAlrion]

You might check if your local library has a 3d printer. A lot of them are doing that these days. Where I live a local air and space museum also has a maker space.

[@KKuurus]

use a spring washer to press against the handle at the rotation point. I'd think about five pounds would do it. Spring washer are curved washers that are thin the tighter you squeeze it the heavy the pressure.

[@Rozbujnik_Rumcajs]

This friction parts are flat so you can easly cut it with coping saw from plywood or mdf. Same apply to big cog. Small cog will be harder to make but nothing impossible. You can simply open stl file in 3d builder (free microsoft software) and print it on paper. Then You glue this to some playwood and cut. 3d builder also can make cross-section of part so more complex elements are possible to make by layering few cutouts - just like in 3d printing process :)

[@kalebclark5826]

Brandon has a good point, a makerspace would be a great resource for printing the parts. If you are interested in this sort of thing it may be a good connection to make anyway!

[@LarkAlrion]

Another alternative to 3d printed parts may be plastic electrical conduit and junction boxes. You can get them pretty cheap at home depot or Lowe's

I was thinking of doing this myself and Im glad iv found this video!

[@fabiena1787]

Hel(l)o. Thank you for this very interesting content. I can see you use a (relatively expensive) encoder that gives you 128 PPR. What's the point, since you could have used a dirt cheap potentiometer on an analog input? There has to be something I don't know, since I'm not in electronics at all. The fact is, I ordered a teensy LC and a few potentiometers to do roughly the same thing (flight controls). To me, the encoder seems rather pointless if you're not going to use it for more than one revolution, whereas a 10 bit reading on a potentiometer could give you a far better resolution (and some room to filter the reading if needed). I don't mean to criticise anything, because I don't have the knowledge to do so in this field, but perhaps someone could explain me. I must be missing something, here. For the mechanical side, which is more my thing, congrats! This is a nice design. I might add some counterweight myself, if I had to use it. This way, the friction plates would have almost nothing to do, appart from giving you the resisting effort you want (no need to deal with the weight, thus you reduce the friction needed and end up with a better feeling, theoretically, and no difference between the push and the pull efforts). Maybe I'd try to implement some kind of adjustable neutral position, but that would become a bit more complicated ;-) But in the end, I'm just typing, and you DID the thing.

[@awhsheeeeeeeet]

I’m in the middle of building a throttle quadrant with 3 linear slide pots plenty of buttons and toggles and an arduino micro, this is my first time even looking at an arduino and I have no idea what the frig I’m doing regarding the code! I have the pots in the analog inputs and the switches wired as a grid into the arduino but the code is blowing my mind and it’s still blank 😭

[@AlexSwavely]

one big reason to choose an optical encoder over a potentiometer is no touch. After a while the wiper contact gets dirty and will fritz out on you. The sealed case on the encoder means it will continue to work until the LED burns out.

[@owensparks5013]

Old thread but the encoders will be perfectly linear which the potentiometers probably won't be, and they won't wear out.

[@jimsvideos7201]

A linear encoder might work better over such short travels.

[@BestUnderPressure]

Exactly the project I'm looking for

[@darknewt9959]

Did you consider using a hall effect sensor instead of the rotary encoder for the deflection measurement? Should give more resolution?

Very good tutorial. I have just built a button box for the h145 helicopter, but I'm having trouble i do not know how to code for arduino i have tried . Many youtube. videos and websites but the code is full of errors. I just need some code for 3 rotary encoders with switch and my buttons are in a 2 row 6 column configuration. Any chance someone can help me with the code please

How could I build your setup and purchase one of these please.

I'm loathe to spoil the comment count and be 129, but I want to know how you apply throttle?

Might be a throttle axis on the joystick he's using.
