Budget Compact 6DOF Universal VR Flight / Racing rig - MSFS, SMC3, FlyPT, Transducers, Controls

Now that the metal brackets are ready, I have attached 5 of 6 motors to the base. I need to take the last motor with me to a friend for fabricating the motor arms



Next, the Electronics Control Box. Planning the layout:


Soldering and connecting components:


Yes, I know my soldering is not good, but those thick wires really suck away the heat, so they are difficult to solder. It looks lumpy, but the contact is really solid. I will insulate it later, of course.


Gluing on the radiators for the motor drivers with a thermal transfer tape:


Soldering the rectifier diodes:


First power-on test, checking the motor load displays:


Almost done:

We've got power!

Here's a video of the first powered test! No sparks, no smoke, so I deem it a success. I connected a single motor and used the self-test buttons of one of the drivers, to make sure the motor was moving. So far so good.

Next, I will design and 3D-print hall sensor brackets and magnet holders, flash the Arduinos with SMC3 and connect the motors. Then I will do the initial calibration. Hopefully next week I will be able to water-jet-cut motor arms, so I can assemble everything, and start tuning the platform. Lots of work to be done.

Looking through your thread I think the motor mount will be too weak, 250W motors are really strong , below is a picture of the M8 rod that was bent today in my 2DOF

I would suggest bolting the mount on both sides with the addition of a steel washer on the underside of the frame

I see what you mean. But to bolt through a 2x4 lumber I'd need really long bolts, and the location wouldn't work well on the underside of the frame. 5 long wood screws hold with a lot of force. I'm afraid that if that's not enough, the wood itself will not be strong enough, or the joints between the frame elements will give. I'll see how it holds on. If it needs reinforcing, there may be other options. i.e. adding 2 vertical metal brackets on the outside that run vertically along the outer wall of the 2x4. Or adding a mirror-image corner bracket and an additional piece of 2x4 on the 0utside to fix it on with another 5 screws.
