Hello all! I know, there already exists a topic about 42110 MODs. But, considering I plan to rebuild the whole car (except exterior) - it really would be better to separate my posts in a new topic (I agree with @Nazgarot). So, for now, I just copy what I posted in 42110 - Land Rover Defender - MODs and Improvements. The actual progress is: - completed front part of the frame (it's stiff enough even without any other part of the body attached): - McPherson suspension and front differential module mounts on that frame and is easily detachable (also McPherson struts include new cv-joints from 42099): - front suspension is built with caster and KPI angles: - engine is built from 4 PF XL-motors coupled together (output gear ratio is 20:36), also it's equipped with one-way clutch (it's built years ago by @nicjasno): - given that drive shaft of the engine has half-stud offset in vertical direction, here is an "offset remover": All modules assembled look like this: And, of course, a video of the short test: This module has some little issues (at first, I need to improve stiffness of the suspension's struts - under load they bend a little bit inward, but it doesn't affect all the process of a drive), but it has a really stiff frame and it's a good start point. You can find more photos on Flickr. About the question why I decided to use XL-motors: XL-s have the biggest torque among all Lego motors (according to the @Philo's page). Buggy-motor has higher rpms, but lower torque (and it's much more expensive and bigger than XL). It's not good choice for heavy vehicles. L-motors are more compact, but, again, if you compare torque/rpm ratio among all of the motors - XLs are the best imho. I tested this setup (4 XLs) two years ago at local fest: This model hadn't any gearbox and was pretty heavy. But, as you can see, the car accelerated easily, than acceleration stopped and speed was constant - only because of low max RPMs of the XLs. Theese motors have very good potential even without gearbox. L-motors are too weak for such acceleration of heavy models. Considering I plan to add a gearbox to this rebuilt Defender - it has to be fast and powerfull))
I was preparing this for over a week and more is coming soon (outdoor reviews will be available on saturday 5.10.2019 and next wednesday 9.10.2019 ). The more i'm playing with LEGO, the more i'm getting addicted. I would appreciate if you could give me a subscribe!

Zerobricks posted a topic in LEGO Technic and Model TeamHere is my take on the motorization of the 42110. Basically the whole model was lifted to accomodate the bigger wheel, motors and BuWizzes. Model is powered by a total of 8 motors, 4L motors for RWD, 2L motors for FWD, one servo and one M motor. Total gear ratio is 1:3. It uses custom portal hubs in the front which have a pivot even closer than normal ones thanks to the new rims. Rear uses normal hubs and wheels, since they are sturdier. Axles use the original suspension's upper arms as mounting points along with a pair of 9L links for each axle. The original gearbox is connected to the rear drive, so it works normally. Steering is also connected to the original links, so steerign wheel and HOG also turn when steering Winch is motorized using an M motor. Video coming soon.
Yes, a long video, but 12 minutes of it is speed build and I'm including chapters below: 00:49 - box and unboxing 03:18 - new pieces 04:32 - pieces in new colors 06:11 - parts list 06:30 - speed build 18:32 - functions 21:51 - impressions 28:38 - final note
