42110 Pimp up my Land Rover




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

- Includes free 213 pages PDF with step-by-step building instructions.
- You will need 166 additional parts to the original set 42110-1.  Use rebrickable's compare feature to see which parts you need.

NEW: Now with Ackermann steering and easy to removable body!!!

v1.3 (2020-02-17)

- Changed gear ratio to slow down gearbox and reduce friction by keeping the same engine speeds like suggested by @Leewan
- Added Ackermann steering
- Added the Easy Body-Removal as suggested by @Pattspatt.
- I modified Pattspatt's solution in chassis and body for more rigidity and easier handling while mounting / removing of the body

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 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
