So I finally got around to building the robot mode of my Kre-O Prime, and boy was I dissapointed. As with most of the Kre-O sets, the proportions were all wrong, and he just didn't look right. After rebuilding Megatron using Split Lip's instructions, I knew I had to do something with Prime so they looked decent on the shelf. So I stripped things down to the basic frame, and spent a couple nights doing one limb at a time. The chest was a little tricky, but after fiddling with it I finally got it to look like movie Prime's truck chest. I turned the red pieces around as I think it has more of the firewall look. It was tough getting all the hinged pieces in there to stay, but after fixing it 10 or 20 times I got pretty good at it. I did use some Lego pieces, but mainly for adding details and the backpack. The majority of the figure is done using pieces from the Prime kit.
