Do these things stay together well and not flop about? I haven't bought any constructbots though been tempted to try a few of the AoE Dinobot ones. It's a neat idea to build your own Transformer.

They do flop around but once stable, the figure will balance itself out. Good point though. actually I am glad they have the oprimus prime 2 pack that I plan on getting today.

I am still working on my Constructbots/KO Constructicons Devastator custom. The only thing I have to do is wait 72 hours before putting him together. As far as them transforming into the 6 individual vehicles/robot modes, I may decide to pass and just leave him together....actually I am going to have to leave him together and wait until Big Lots have some more so I can buy them and repaint them the traditional g1 colors and use them in their robot/vehicle modes....and then use Devastator as the final combiner mode.

AWESOME!

I am working on a Constructbot style G1-ish Constructicons from the KO series
