    I suppose that depends on your expectations. There's a reason that real electric vehicles do not have gearboxes. In a LEGO model like this, it is really a demonstration of the mechanical principles involved rather than a way to drive faster or with more torque. In that I think it succeeds admirably. The transfer case is really cool. It has four modes: RWD, 4HI, 4LO, and 4LOCK. You can surely see the difference when you have the vehicle elevated and watch the tires. The locking diffs are a really good trick. The main gearbox with 5 speeds and reverse works fine, but you won't see a huge difference in actual driving speed because you are limited by the power of the battery box. You can see the difference better with the tires off the ground. It is not 100% reliable. Sometimes multiple driving rings engage at the same time. But I found the whole build experience very fun and educational. Many times I thought, "what is this part supposed to do?" only to figure it out 30 steps later when the final detail was installed.

    Very fair. It is always very helpful to read the comments about a model from an experienced builder like you :)

    Just finished building this last weekend. I wanted it to look like a totally scale model, so I bought some aftermarket R/C tires with a scale BF Goodrich pattern. They are pretty large so I needed to build with the portal axle option for extra suspension height. After several hours with a paint pen, I was able to give the tires raised white letters. I love the result.

    How do you like its functions? Based on others reviews I have a feeling that the mechanism may be too complicated to the point that it is not reliable or performant.

    I have mixed feelings about this MOC. I like the functions very much. However, it is a real pity that switching gears doesn't seem to make much noticeable difference when driving. That's even worse than the Land Rover Defender 110 which is much bigger. The BMW i8 is much better in that regard. Regardless, that is really understandable given that this is LEGO with LEGO PFs after all. Still a masterpiece.

    I just finished building the Invisible Lift. It is just awesome and impressed everyone who looked at it!

    At first the machine kept dropping balls at the first a few antennas. But once I follow the assembly video by TheRebricker to adjust the timing carefully (it is great that the machine is designed in a way that you don't have to take anything apart to adjust the timing), the machine works quite reliably. It still drops balls at a pretty low rate though. Another issue I noticed is the ball unloader. Over time, the connection will become loose and the claw is not tight enough to grab the balls. I had to tighten the connection once in a while. Is there anyone who managed to make the machine running for more than 10 minutes at 100% success rate?

    I also added return tracks at the back of the machine. I basically copied the design of the Cycloidal Drive. It was a bit harder than it seemed to get the angle right so that there's enough room for a second track, and the balls would not run too fast to dash out of the track.

    It has been a great fun building this machine. BIG THANKS to Blakbird and TheRebricker for the instructions!

    Which one would you recommend if i could build exactly one, so what is the one and only?

    Which two would you recommend if i could build two. These two should be able to be linked together quite easily, ie. the output of the first should directly go in the Input of the second one.

    That is pretty hard for anyone to answer for you because the depends on what you find interesting. If I was going to have only one it would probably be the Invisible Lift and if I were to add one more it would be the Cycloidal Drive.

    I had the same question. I wanted to build a mini circuit with just one Akiyuki module. I thought I would definitely consider the Ball Factory first, and then probably the Invisible Lift (which should be easy to add a return to to complete a circuit). But after reviewing many posts I am a little hesitant now. You didn't recommend the Ball Factory, is it because it is too hard to get the timing right, too easy to break down, less interesting to you compared to the other two, or simply because the instruction is not ready yet? :)

    $250 seems cheap for this build. I have a hard time with Brickefficiency (4 stores) to get a reasonable price for all the bricks needed to build the ball factory.

    I already have most technic parts. I have very few system bricks. Here's how I divided the orders by Brickefficiency.

    First I removed all the technic parts. I will place a separate order if I still need some technic parts after sorting out my inventory. I also removed the buckets and the base plates. I will buy then separately. Then I changed all the yellow parts into black. That's just personal preference on the color scheme. I also changed some dark bluish gray parts into black since I found black ones are available in more stores. After the chances, I was able to find all parts in 3 stores for around $150.
