I tried it. The Arcadia stand is a brick. I would be happy if they packed it in with the YF-19, or at least sold it separately. It holds up my VF-19 in all modes. The arm locks in place at all joints, and you have a pivot on the top where you plug in the valk connector, and even that one needs to be removed and reattached as it does not rotate freely. It is more solid than my Yamato launch arm stand.
I do hope they revise the storage covers, though. I have to use a tweezers to lift them up.
