After recieving the Wreck Raider set last month, I spent a couple days seeing how many different things I could build from it. All the pieces used in the pictures were from the set except for the stand used in some of them to hold up the vehicles.
The underwater "jet pack"
This speederbike-ish vehicle is my personal favorite.
For this one, I was aiming for the asymetrical look with the diver on the side of a large jet. Not a bad idea, but it didn't turn out as good as I'd hoped.
The ever-popular mech alternative. Since such a large number of set alternatives involve a mech, I had to at least try with this set.
I like the shape of this one, but the way the diver fits in just doesn't quite work.
I started out aiming for something like a giant-underwater-snowboard type vehicle with this. It didn't turn out quite as good as I wanted it too, though.
And, finally, an underwater scooter. Not the best, but kinda cute.
