Also, if this helps anyone- for some games, i use a logitech g29 FFB wheel. Obviously, it means even more cables- power and USB. I bought some extensions for it which is work fine.
For power, i bought a cable that extends the power cable for the G29 wheel: https://www.amazon.com/gp/product/B00FT9VW0O/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1
And i used the usb extension cables i mentioned above- the pimax itself has a USB-c port on the underside- i used the usb3 extensions i mentioned above, along with a 45 degree angle adapter so the USB3 on the bottom of the pimax isn't sticking straight down:

I also used it with this 1 meter USBC extension:

So, from the USB C port on the pimax, to the 45 degree angle adapter, to the 1 meter usbC extension, to a usbC to usb3 adapter, to a 10 foot USB3 extension cable, to the USB3 on the laptop.
Yeah! i figured that somewhere along the line with all of those things plugged in, there must be a problem, but it works flawlessly. The only problem is using a usb extension cable on the pimax main cable (audio is distorted) like mentioned before..
I think some people might be wondering, why do i need so much extension?
Well, have you seen some of the new motion simulators! Check out this YawVR one- it's amazing- the base model is $1500US, the deluxe is $2k- the difference is the deluxe includes more powerful motors so the motors can deliver more oomph, and a few other things.. Here is a video that shows it off..
