VKB-SIM

Hi, I’m planning on getting a STECS Max setup mounted on a UCM with the STEM vertically. Since I won’t be needing the MFH and don’t want one just laying around for a while before getting thrown in the trash, I was thinking that it’s better to order just the STECS Standard set and the ATEM module. Plus of course the UCM with miniplus plate.
I figure I’ll also have to buy the type-C bus cable but is that it?

It doesn't make sense to pay for something you won't use, so STECS Standard, UCM and STECS Mini Plus plate are making more sense in your case. You'll have to swap the STEM with the ATEM on the throttle and mount the STEM horizontally on the UCM. You will only need the USB-C to USB-C cable to connect the STEM to the STECS.

Mounting the STEM to the UCM separately also requires the STEM back cover.
