DIY FFB flight stick discussion on DCS World forum

This might be of interest to some people.

There is a thread discussing a couple of different options for a DIY FFB flight stick on the DCS World forums.

First one is a from scratch solution. Using an Odrive and some brushless motors.

Plans for this design can be found here

Another stick here. Developed independently from the first. Also using brushless motors

There is also some talk of modifying Microsoft Force Feedback 2 sticks. But you can find much better info on doing that on the following pages.

Hi @Tehrawk !
Thank you sooooo much for sharing the links here! Last year I started FFB rudder pedals. As a motor controller I used the "moteus" bldc servo controller. Everything was working well, but the forces have been little too low for Rudder pedals and I didnt like the noise comming from the motor and controller. So currently I use the pedals without FFB. The Odrive solution shown in the link is a new chance - so thanks again!

These are the motors that the OP from that thread is using. The torque is 8.5Nm, which seems crazy to me.

They have been on back order for months though.

Speaking of rudders. I really like this design. It looks like a cheap Thrustmaster TPR. Could easily mod in a motor also.

Ah..yes..this was also a source of inspiration for my rudder pedals. Here in the assembly stage some months ago. It works so good in my sim.

That looks really nice. How did you machine the metal?

I have acces to the Makerspace in Garching nearby Munich, Germany. They have a waterjet-cutter.
But for a maybe future version I would order the parts in one of the online CNC shops. At the end this will be the cheaper solution...

Thanks for posting. Save's me some questions and research! Just need more power and accuracy than the good old msffb2 can give even with triple power.

in that forum, everyone building with bldc and odrive, that is very expensive.

i just wanna build with brushed motor and cheap motor driver just like my steering wheel...do someone have some clue what firmware and software i can use or maybe there is some good starting point for me..??

There could be a solution, using hoverboard motors. Then hacking the firmware on the PCB that comes with the hoverboard.

but they are directly using odrive as HID + motor driver...

usually i build regular steering wheel using separated microcontroller and motor driver (mmos2014)

maybe if they implamented like that, other user can easily copy and using that...

Here is a wheel setup using an Arduino Leonardo and hoverboard components.

yeah that will be great project, but if we have more option for output signal, that will be great, at least for me. because i like build using simpler dc motor and cheap hbridge...

They are talking about re-terminating motors to the Wye(star) pattern, to give 1.7x more torque.

What is this witchcraft!

Delta is more prominent, because it is easier to manufacture? Plus hobbyist's are usually looking for more RPM, rather than torque.

Edit:- Looks pretty straight forward. You could do this to a hoverboard motor, and get 17 Nm out of it.
