Update 9....Upper arms secured with Lego technics and rare earth magnets. The look is more than i expected when beginning this project. He has that menacing upper body I envisioned. The build is ALMOST DONE!!!! Update 8....Connection between arm cars and lower arms complete. Full range of motion available in both elbows as well as a very secure connection. The hands are not the final ones, they are there for scale and look right now. Next, onto the conenction to the upper arms! Update 7.... 99% completion of lower legs and feet, those won't and can't be completed until the Barricades are repainted. Thighs are 100% completed with extra magnetic attachments and sliding compartments for the Barricades to better lock in. Add more bulk ot the upper body and attached the framework for the arms using an ultimate Starscream's thighs and leg connections. Reinforced them to allow them to take a HUGE amount of weight. Next I tackle the arms..... HA Bumblebee and HA Sideswipe are just placed for scale and weight check. Anyway, comments APPRECIATED! Update 6.... Totally reworked the feet to a larger, more stable setup. Also had to separate and widen Unicron's crotch to make him look more proportional and allow the legs to sit next to each other with clearance for the new feet. Update 5.... more build up on the torso, added electronics, more refined feet for better and more stable balance. Update 3 & 4.... I have the mock up for the chest and torso cradle, as well as the feet completed with magnetic attachment and springs like the Fallens feet for grip. Update #2 - 2/13/10.... got the cradles and some connection points for the torso (Leader Class TFTM Optimus Prime) as well as some of the structural supports for the waist done. Here is a mock up.... head is there for reference only. This is literally 5% completed.... A LOT more will be going on this. Animated Megatron for scale, the HA Barricades will not stay police cars for long.
