Building Optimus Prime Ep. 20: Lower Body Assembly + My BIGGEST BUILD MISTAKE! | Agora Models v LEGO

Click Image to Launch YouTube.

Happy Transformer Tuesday! Episode 20 brings major progress on the lower body/abdominal section of Optimus Prime, but also features my most embarrassing build mistake yet - installing the spinal column UPSIDE DOWN! 🤦‍♂️

🔧 What We Build This Episode:

- Scale Model: Complete lower body/abdominal assembly with metal components

- Scale Model: Ventilation fans and grill installation

- LEGO: Optimus Prime's iconic head assembly (Steps 324-340+)

- 20 scale model steps (30 parts) - but really 40 steps because I had to rebuild!

- 23 LEGO steps (45 parts)

😅 The Big Mistake:

Watch me discover I installed the spinal column backwards and have to completely disassemble everything from this episode to fix it! As fellow creator World of Wayne says: "I make mistakes so you don't have to!"

⚠️ Lesson Learned: Always double-check part orientation before securing - it can save you 30 minutes of rebuild time!

📊 Total Progress:

Scale Model: 656 steps, 770 parts used

LEGO: 485 steps, 1,177 parts used

🎯 Only 4 Episodes Left! We're in the final stretch - upcoming: arms, chest, head attachment, and weapons (axe, Matrix of Leadership, ion blaster)!
