I'll have a sheet up soon! 
Just noticed your link says 'VF-1 Phoenix' whereas it should be VF-0, if I'm not mistaken. I assume that the SV-51 and 52 are close enough in appearance/design that there's no need for a hard distinction; that and there's very limited info on the SV-52 anyhow. I did, however, manage to find these. Not sure if the slight differences in design would be found in all SV-52s or are exclusive to this SV-52y variant. The wings are unique, especially the sets of 'tips' on the end. In Battroid mode, the head's also a bit different.
