Well no Surprise here. I think a lot of people have though of doing this already. I’ve seen a WIP and I saw spoonman’s recent post. In fact I believe we used the same head. I was going to work on Rumamuck once I get an extra Wheeljack. I felt this mold so far has many of the aspect that translated well to the battlecharger brother, next to the Bumble bee mold. Hope you guys like it FYI for anyone else who want to do this 1) If you want to use the Cybertron Runamuck head you will have to shave a good 1/3 off the back of the head to have it fit. Especially if you plan to keep the chin. I have a pic of it though it’s a little blurry. I posted it at the end. I sanded it up to the line as pointed out by the screw driver 2) If you plan to paint the windshield you may want to sand where the rear view mirror a little to keep it from rubbing the paint. The mold otherwise has not caused me much trouble in paint rub during transformation.
