These are my improvements to pimp up 42110 Land Rover Defender.

- Includes free 207pages PDF with step-by-step building instructions.
- You will need 94 additional parts to the original set 42110-1.  Use rebrickable's compare feature to see which parts you need.

v1.2 (2019-11-13)

small bug fixes in part list, MPD and PDF.

v1.1 (2019-11-12)

The original design had these mistakes:
  - shifting up lead to higher revolution of engine
  - reverse gear ratio was comparable to 4th gear
  - Hi / Lo switch did not effect reverse gear
And these weaknesses:
  - low engine speed in total
  - high torque in gear train and stick-slip caused by universal joints

So I redesigned a complete new gear train sequence including DNR, Hi/Lo and 4-speed-gearbox, that in the end came out with direct connections without any universal joints:

- 4WD transmission geared up using 16/16 gears instead of 8/24 
- center diff geared up by using 24/8 gears instead of 16/16
- then and goes to Hi/Lo selector first. Hi is normal drive, Lo is for off road use
- then goes to DNR selector (Drive/Neutral/Reverse) with 1:1 gear ratio between 1st gear and reverse gear
- in D selection the 4 speed gearbox will be connected by direct axle connection without universal joints
- gearbox output goes directly to engine without using universal joints
- avoiding friction by not using stop axles in gear train
- axles always guided on both sides of gears (best practice learned from didumos69)
- geared up drive train to have faster engine speeds
- gearing up by moving gear selector wheel to the right and gearing down by moving left
- Hi/Lo selector works as indicated by the Hi/Lo stickers

Reducing friction and adding stiffness to steering mechanism

Small modification of rubber band fixture at the rear door closing mechanism as suggested by Coolusername

    Hello, This is my very first modification, your modification can be motorized ?

      This MOD is not designed to be motorized. My main focus was to improve the technical features for manual operation. If you are looking for RC there are some other MODs available.

    Great modifications. I built your 42056 and 42083 and now will do this. Before I order, I was just wondering where the extra 2 green L-shaped liftarms are used? They are a bit uncommon at the moment, so do they have to be green?

      Which extra parts do you mean? I only see 8x Beam 2x4L and 2x Beam 3x5L in olive green. These are the same parts as in the original 42110 set, no additional parts, if you own the set.

    Suggestion for v1.3: Add V6 lego engine (or possibly a V8) in stead of the fake engine of the original. And redesigned rear door hatch, I have spotted that somewhere. And working door hatches. Keep the good stuff coming!
