Posted January 15, 20187 yr I’ve been troubled by the vulnerability of LEGO parts on heavy models for a long time. Especially some crucial parts related to drivetrains, like universal joint, bevel gear, etc. One solution I can think of is to distribute torque by using multiple drivetrains. Instead of using 2 groups of motors driving the wheels on each side respectively, I built a live axle chassis with a dual-drivetrain system. In this way we don’t lose the benefit of differential while cornering. I actually designed 2 experimental MOCs utilizing this system. Today I’m gonna show you one of them - Mitsubishi Pajero. Bodywork is based on the very first generation of Pajero series, which was introduced in 1982. Some details have been exaggerated for a better looking, like the bull bar, rooftop, and engine hood. This MOC is built more for aesthetic purposes. Due to wheelbase concern, it’s only rear-wheel drive. Luckily both front and rear suspensions are quite responsive, which will help just a little bit on tractions when driving off-road. Each drivetrain is driven by an L Motor, rotates in opposite directions, and together they drive a single differential. I also managed to put a 2-speed linear gearbox in it. some renders to show them all: Outdoor test: I never expected it to have a great performance given the fact that it is 2-wheel drive and those 62.4mm tyres have a really bad traction. I think it is acceptable for its configuration. More photos: Upcoming New MOC This new MOC is a 4x4 model with a similar but different drivetrain. It is still an unfinished prototype, but I can’t help giving you guys a sneak peek of it. Stay tuned and enjoy Edited January 15, 20187 yr by KevinMoo
January 15, 20187 yr It's very visually accurate! I particularly like the use of two drivetrains from the motors to the differential, is it like that on the real model?
January 15, 20187 yr I've always loved your work and this is another gem from you More importantly, though - how are you? I seem to recall you weren't doing too well some weeks ago.

To be honest I really don’t know. This MOC is not aimed to recreate the real drivetrain.
January 15, 20187 yr Looks great, and performs surprisingly well. The next model appears interesting as well, I'm guessing some sort of performance offroader...
January 15, 20187 yr Really like all your MOC's. Have build them all and looking forward for any new MOC's in the future!! This new has a very unique drive train and it will be fun to try this out...thanks!!
January 15, 20187 yr Nice MOC. I wanted to buy a Pajero IRL, but I bought a Ford Transit Custom instead. How about a MOC of that next? http://photobucket.com/gallery/http://s372.photobucket.com/user/fordfiestast_co_uk/media/Album Nineteen/20151018_085843-1_zpsorow7ffd.jpg.html (not mine)

January 15, 20187 yr Wow... I love how compact your designs always are. The looks are splendid and great functions to boot. Keep on building!! Can’t wait for the new one
January 15, 20187 yr This is awesome I love the compact mechanics of it all! And the body looks great, the added bits like the bull bar really suit it
January 15, 20187 yr Great model, and beautifully photographed. The windows do look a bit high, but when searching for pictures I saw the Pajero junior also has a pretty high body profile. Very smart drivetrain
January 16, 20187 yr Looks great! There's lots of interesting assemblies - including the door handles, which I like. I also like the use of a small wheel as the steering wheel - it's a much more realistic size than the pre-made ones.
January 16, 20187 yr Wow, this is great. The drive train is very interesting - nice to see an old school linear gearbox updated with powered shifting and for the dual drive trains. The use of connectors on the bodywork and seats is inspired - the row at the side of the bonnet and along the top of the sills really helps give it shape - nice work! Also great to see the steering wheel on the right side (both senses of the word!) :)
January 16, 20187 yr Excellent work! The drivetrain and the chassis are very well done. The symmetry in the dual drivetrain is a very 'good smell' imo. And I love the bodywork style ! Edited January 16, 20187 yr by Didumos69
January 16, 20187 yr As I said before, level of detail, presentation and overall look of your models is the same as top-builders do
January 16, 20187 yr Its the little details that appear when you look for the third or fourth time, like the passenger grab rail on the dash, or how the rear tow bar is integrated into the rear bull bars There is a lot of clever design, and integration of beams and joints, certainly another master class in building.
