I would like to thank you both for the clear explanations!

Hi! I ended up installing the center differential. As I said before, the front wheels rotate, the rear wheels are dead. But if I "lock" (I mean, grab and hold with my hand) the center dif, then the rear wheels start to rotate and it becomes a real 4x4. Is this the correct way to make it a 4x4? Locking the center dif, it's 4x4 and unlocking it it's a 4x2?

Hi folks! I'm adapting two L Motors in the defender. They are near the end of the chassis and are connected together by a gear between them. Here are some pics Top view Left view Bottom views This is the main axle. It is connected to the front and rear differentials. With this setup, the front and rear wheels rotate in different directions when the motors are turned on. The rear and front differentials are on the same orientation as they are in the Lego build instructions. I also tried to put a center differential in this position of the main axle, but only the front wheels rotate when the motors are turned on. The rear wheels did not rotate. What am I doing wrong?

Hi there! I got mine from a store called element in brickowl.com. They are in Florida. Brickowl is like a market place with stores that sells Lego parts. Do a search at it and maybe you will find a better deal. I’ve just checked and element still have it available. https://element.brickowl.com/store/lego-servo-motor-set-88004

Hey! Thanks for the explanations! Another one: I got the MPD file for the defender in this link: https://forums.ldraw.org/thread-23139-post-34344.html#pid34344 Imported it into Studio 2 but it looks like there are some missing parts. Any one know how to solve it? Or have another file to share? Here is how I see it: https://imgur.com/0enL6tA

Hi there! I'm not new to LEGO, but I'm new to Technic sets. This was my first LEGO set back in the 80's: Police Station I've just finished building my Landy and faced the same difficulties already posted here regarding the gear box. I got a couple of L-motors, a servo-motor, lights (all power functions) and a Buwizz to go for an attempt to make it a RC model. I really enjoyed a lot of modifications I've seen here and I would like to implement a lot of them. But here in Brazil there are almost no way to buy spare parts and the LEGO sets are expensive (a friend of mine came from USA and brought my Landy and motors). For now my objective is to make it RC. For this, I would like to ask for help of the Technic experts here. I want to build a simple drive train, with just HI (for a some speed gain), LO (for torque and power) and N positions (that would allow the wheels to rotate freely). Of course I want to couple the 2 L-motors to this drive train. For the steering I'm planning to go with the Anckerman setup I've seen here in this post. But there are some restrictions to the project: - I want to keep the exterior and interior as much as possible. - Remove all the gearboxes, engine, etc to have space for the drive train and motors. - Make a symmetrical chassis. - It can use only parts from the 42110 set. - I also have set 42102 so I can use it's parts (if needed, prefer not). My main difficult it to put together the drive train. Can some one help me, may be with a studio.io file? The other things I believe I'm able to do. I also have two quick questions (3 actually): - Whats the purpose of the center differential? What problems can I have if I remove it? - Is it possible to use M or L motors for steering? Any help will be greatly appreciated.
