Review: Thoroughly pleased with this kit. - This is my first Ugears kit and chose this one because it appeared to be one of the more complex models and expected it to take several hours to complete. I watched a few YouTube videos and knew what to expect and when it arrived, it did not disappoint. Everything was nicely packaged and I also appreciated the spare parts on pieces more susceptible to breakage. The kit took me about 13 hours to build and this is because I took my time. I properly sanded and waxed all moving parts and also checked operation every time something new was added on. I did manage to break the cam shaft while pressing in the valves and had to disassemble the engine to replace it but the spare parts saved me from needing to order another. The model works exactly as it should. It winds up, the engine runs and forward and reverse are both operational. Now that I know it works, it’s just going on display on my desk. Anyone who thinks this is a toy is mistaken. It’s very delicate and many pieces will need replacing if you continue to goof around with it. I’m okay with that though. Anyone building a car out of thin wooden pieces shouldn’t expect it to stand up to repeated use and abuse. It’s a great kit. The laser cut pieces are absolutely perfect and everything went together just as it should. There’s a few challenging components during the build but that just added to the appeal for me. Can’t wait to build another one now!
Review: One of my favorites! - This was a very complex and time consuming to build. I loved it! the working motor is amazing. Sanding and waxing is the smaller parts in the motor will make this run like a charm. It is fast and looks amazing! I just loved this one. The instructions are great. the spar parts are great. im not to happy with the "hand crank' used to wind this. the gear and crank broke apart quickly. You do get spare parts for these however. caution is needed when winding. I coated the extra parts with white glue, let dry and lightly sanded. this will harden these vulnerable parts. I have had no issues since. I would buy this again. Just a joy to build!

### ⭐⭐⭐⭐⭐ VERY complex drive mechanism.
*by A***K on March 10, 2020*

This was my second attempt at this model. It is important to SAND & WAX the indicated parts. I used a Dremel tool with a buffing pad to apply the wax and get a mirror finish on the parts. No joke, it's the only way to get this thing to move on its own when you crank it up. Anything less and it will seize up on you. The problem is not the individual components, i.e. engine, drive shaft, final drive. It's when you put them all together is when the issues start. The engine is a marvel with working pistons and valves! I spent some time on this chamfering the crankshaft edges and polishing all contact points. The final drive especially is intricately engineered and very delicate. The parts #103 are impossible to install without breaking and will require some super-glue to attach, it's a cosmetic part so NBD. Overall I really love these UGears puzzles. They are seductively challenging and, with a bit of skill and luck, you end up with a very nice mechanical display piece.
