Yes, on top of everything else, I think he was skilled in that too. Some people say nah but here's my "proof" which I base of completely on Minato's evaluation:
Minato who obviously knows the history of Konoha and the abilities of the former kages had thoughts rushed into his head when he met 'the masked Man' (Obito).
When analyzing his abilities, his thoughts went from this (ch.502 page 10):
to this (page 11):
so one of the points that lead him to the conclusion that the masked man would be Madara, was that he was capable of using s/t techs. We can't really disregard it.
ps. I'd like to add to this the fact that Tobi was trained by Madara. He learned how to use space time tech from Madara. Even if it was Obito's original ability from his sharingan, Madara was the one that made it possible for him to advance in s/t technique so that he is on the level that makes Minato say this:
Obito obviously can't get onto a level higher than Tobirama by himself. So he was taught by a teacher stronger than Tobirama: Madara. So there's a strong hint that says that Madara knew s/t.
Remember Naruto wouldn't been able to have learned Rasengan if Jiraya didn't knew it.
Opinions?
