No real complaints from me on this guy. Robot mode looks real cool and is fun to pose with very nice articulation. Helicopter mode is a bit larger than the other limb bots, which is good because it's a frickin helicopter. Combiner arm mode is nice too.
Getting his sword unsheathed is a bit tough but doable enough and I'm not really worried about it breaking because Vulcan comes with a replacement set of blades for him that are supposedly more sturdy.

Note: This product came damaged and it appears that it was again a manufacturing problem. The sword was not properly formed and just slide apart when removed from the package. TFSource replaced it fast, thanks guys! There was also a problem with front of his helicopter cockpit popping off. Inside, I can see it is another manufacturing error, not a bad on as it makes it easier to transform though. But it should not pop off.

Vehicle Mode: Nice feeling helicopter and the guns fit nicely on to him. Like some of the little features here and there on him.

Robot Mode: The tail rotator is kind of odd on the legs but the blades make an awesome sheathe and sword.

Combiner Mode: Strong looking arm. Feels powerful and weighting in look. Just what you want.

My favorite of the Guardia units. Sadly his sword broke the first time I tried to remove it. Waiting on a replacement from the fantastic guys at TFSource. I know that MT is issuing a replacement if/when you buy Vulcan, to form Guardia. If it wasn't for that, I would give this guy 5 stars. I LOVE HIM! The unhappy look on his face, is fantastic. The good guys should get a little mad from time to time.
Also, this mold reminds me of Blackout from TFmovie.

This little fella is a pain but looks so good.. his transformation isnt as free flowing as others. he is like his brother fellow protectobot Rover.. very sturdy solid and articulate just hard to get piece's to line up during transformation .
