Nearly 5 years ago, I made this guy and it turned out to be quite a hit. Click below for the mocpages.com gallery for Optimus Prime:
Even though the Apex Armor for him had been dismantled , I still keep the cab. Only recently I finally think it's time to release the instructions for him.
For those who does not have the right colors for the parts to build him.. don't let that deter you. Just build him using a different color scheme. The most important thing is to have fun doing it! And when you're done... maybe you can email me your works/improvement and I'll put in up here in my blog.
