This is a mod I did to my first Classics voyager Optimus Prime close to four and a half years ago. I saw him sitting on a shelf the other day and realized I never shared this mod. I figured it was about time. One constant criticism of this mold is the arm panels. For some reason those never bothered me. What really got on my nerves was the big ass grill and front axle hanging off his back. It disrupted the rather nice silhouette of this figure. Here's what I did about it. First you want to remove the four screws from the back of his lower torso. Separate the lower torso taking care not loose any pieces of the ratcheting joint inside. There will be a screw in the middle of the back half of the torso. Remove that screw. Just as a little optional step I forgot to show take the upper torso of Prime and flip it over. You'll see 3 screws. Take them out lift up on the panel. This is the seats and steering wheel in side the cab. If you want you can paint them to add a little detail. You might be able to see I painted the seats black. Give a tug on the whole grill/front bumper and it will pop right out. Reassemble Prime once again taking care not loose any parts to the ratcheting joint and you'll have slimmed down Optimus Prime. You'll probably notice here on mine I removed the blue paint from the shoulders and added a craptastic home made Autobot badge. This mod kind of does to Classics Optimus what the wing mod did for Classics Megatron. It improves, in my opinion, the aesthetic of the figure however you sacrifice the clean transformation. When transforming Optimus just spread sides of the cab open a little and peg the grill assembly into the hole where the screw was. Just like the Classics Megatron mod you won't be able to tell anything has been done in alt. mode. The connection is so secure when you tab in the grill you can do this... It was long overdue, but I hope you enjoy my simple mod.
