It has been a while since my last review, when I decide to write a review about this set, many others hv made great reviews/video Therefore I would better skip the review section and share some additional play mode of this set instead The first thing is the light saber mode of Bulldozer, I tried to plug Light saber parts (from HG gundam model) into the "handle" part of bulldozer, and it is pretty fit, and it works exactly like gundam's light saber. I wonder if there will be any extra laser parts in later release? The next mode is the giant arms mode! It works in both Bulldozer and Excavator! The drill part I used comes from Bandai LBX model series Finally I want to share a transformation tips of bulldozer, there are interference problems of flipping the lower body over if you follow the instruction To make it easier to tranform 1) flip the whole "Giant's upper arm part" down 2) rotate the lower half 90 degree 3) flip the lower body over for 90 degree, there shouldn't be any interference The key point is to rotate the entire lower body 90 degree Too bad I not good at making video, I hope the pictures help!
