Does anyone have any full power armor sets other than the one you get at Concord, if so where did you find them?

I have three sets. I found them by exploring down the west side of the map. Just keep exploring; they're out there.

You get a set of t-60 from joining the BoS

Also, there is a quest in goodneighbor where you have to help someone break into a place using a robot that can create sonci blasts to dig through the ground. there is one path found by doing this that leads to a Mikelurk King and a unfinished set of T-45.

I also found an unfinished set of t-45 on a truck (though forgot where), that you had to unlock a terminal to get to.

EDIT: actually, one of these is a unfinished set of T-51, cannot remember which one though.

thanks guys, I'll take your ideeas when I'm able to play tonight

Go to Fort Hagen. Directly south of that and south of the clinic there is a suit of T-51 armor in a derelict garage. Also has a ton of repair stations. Also go directly due east of Sanctuary and you can find a downed Vertibird with a fully intact suit of power armour just standing there.

There's a rusted set of t-45 (missing a leg piece and helmet) just north/ north-west of the satellite array (near Sanctuary). You'll see it amidst the wreckage of a vertibird crash.

There's also a full set of t-51 armor at an army depot in the north-east part of the map; one of the BoS quests should take you near the area.
