Wow! Lots of clever techniques here! Love the arm transformation! I, too, really like those 1x1 w/towball pieces! All my new Transformers use them...so versatile! Vehicle mode is super smooth and robot mode is very articulate as always! I'm actually nearing completion of a brick built version of my Bumblebee V3 LDD. You've set the bar high with this brilliant model! Well done!
That windshield transformation to allow his head to rotate up is super clever, and the foot transformation was so simple yet effective. Also really excited to see more G1 bots using this frame as they appear to scale almost perfectly to my transformers :D
