Review: A Blast With Caveats - There are a lot of parts and I made some mistakes along the way, but I am thoroughly enjoying this project. There haven't been any missing parts so far, so I feel pretty confident that I'll finish without incident. I just started step 4. There are very few written instructions and some of the drawings of the connecting pins in the instructions aren't quite as clear as I would have preferred. I'm having a blast though :)
Review: Awesome Build - just started building it, after i did the v-8 which was also a very good build. 1/2 way done so far and no problems, and no pieces missing, wish they would have came out with these type of builds awhile back, building cars, ships, etc, is fun but these kits sort of changes things up, or just something different to build. i hope they keep coming out with these kits. the bricks/stones are very nice the clutch/or snap are very nice. A+ to MouldKing will buy again

### ⭐⭐⭐ Fun but missing small piece and mistake in directions
*by J***. on January 16, 2025*

This has been fun to build with my son. Not Lego but was pleasantly surprised at the quality. As others have said, we are missing a small piece. Main purpose of review is to show what seems like a mistake we found in the instructions for the belt/chain tensioner, step 313. The way the instructions state, the tensioner cannot move. We left one black piece off and it works great. See pics.
