Surprising, as it makes the engine run faster.

Fair enough. Then it is just the instruction that is not correct on this tiny detail. Not a big deal, if you ask me.

2 : Who told you LA input were supposed to be orange ? They are dark red. 4 : Use your nail (or the edge of any Lego part) and push the axle out.

This is because of the scale. It is just a bit bigger than 75179, and so it gives a lot of opportunities to tackle the model in a different way. The interesting thing here is that you generally don't need to increase the size like crazy (+100% or +200%...) to go from a minifig scale set to a UCS model. +40% / 60% is generally more than enough. You can check with many UCS sets and their minifig scale version (TIE Fighter, B-Wing, ISD, Slave 1, Y-Wing, X-Wing). There are few exceptions, such as UCS MF and UCS Snowspeeder. edit : my UCS TIE Silencer in "only" 44% longer than 75179.

See my review on Techlug : http://www.techlug.fr/review-lego-technic/42110/land-rover-defender-42110-milan-reindl-2019 You will have all the pictures you need for whatever you are looking for in that set.

A black 12t on the yellow axle is missing. This axle is the exit of the main gearbox. No other gears on the red axle than what is shown on the picture. This axle is the entry of the main gear box. Entry / exit : with a way from the wheels to the engine of course.

That would be an option. But it makes the "slow mode" with lever at the front, while it would make more sense if pushed toward the rear.

And now what do we know from 42056 and 42110 ? TLG really has hard times with gear sequences. :D Full review here : http://www.techlug.fr/review-lego-technic/42110/land-rover-defender-42110-milan-reindl-2019 In French, but you may translate. Loads of photos. Full gear ratios (from differential) : Low : 1:0,93 ; 1;0,56 ; 1:0,31 ; 1:0,19 High : 1:0,34 ; 1:0,2 ; 1:0,11 ; 1:0,07 R : 1:0,11 So you may have note that low 3rd and 4th, and high 1st and 2nd use the same range. This is not realistic but it's not such a big deal.

Indeed ! I actually never apply the stickers. Didn't see that hi-lo sticker was printed that way. To me it is obvious that when lever is push at the rear, it makes a multiplication (from the wheels towards the engine), and so it is Low gear. So, to sum it up, @kbalage you were right : both stickers are wrong. At least from a true mechanical perspective. It kinda reminds me the thing with 8457 power puller and the "arm with muscle" thing. You know, to explain the variation between speed and torque. The way TLG explained it was wrong.

Let's consider that when lower gears are engaged (either in the hi/lo gear box or on the main gear box), engine is supposed to move faster (which is only logical btw). So, hi / low gearbox and sticker : With this : On this picture, it is a reduction (16 => 20). So, it is the Hi mode (to drive). While on this picture : This is a multiplication (20 => 16), so it is the Low mode (to go over obstacles for example). Then on the main gear box at the rear of the car. Which looks like this : Starting from the axle with DBG 24t gear, gears are (and look at the olive green part at the same time) : 1st gear : 24:8+ 16:16 + 20:12 => x5 2nd gear : 24:8 + 16:16 + 16:16 + 16:16 + 16:16 => x3 3rd gear : 16:16 + 16:16 + 20:12 => x1.67 4th gear : 16:16 + 16:16 + 16:16 + 16:16 + 16:16 => x1 So I'd say that only + / - sticker is wrong.

I analyzed the model in depth, and I would say that the high / low sticker is correct in the instruction. But + / - sticker (the thing with black brick 2x2 round) is not correct. Given gear ratios, + should be on the right, not on the left. Can anyone confirm ?

As I said, I didn't do all the maths yet. I will within the next 2 or 3 days. I just built the model as shown in the instruction. And checked, double checked, triple checked and more everything. So I have no building mistake. Just imagine that I was so baffled with the thing not working that I even checked twice if I used a differential in the wrong way. After 25 years of Technic, I am glad to say that I didn't do that rookie mistake. Phew !

I said 1 gear. Not 1st gear. ;) The engine rotates faster in lower gears of course. Yep. And because it is the only way that makes sense.

Reverse works fine. 1 gear is more or less ok with right lever on High. All other gears crack. U-joint are properly aligned to have constant velocity.

As far as I am concerned, they don't.
