    Progress update. this is the final version of the steering, big thx to Jurss for the help: steering works great, the angles are very wide and the suspension is a litle wobbelly but it works fine. For the rear suspenison, I used a four arm system for each wheel. This allows the wheel to stay perpendicular with the ground at all times regardless if the suspension load. I know I used a yellow suspension instead of a grey one, and that the left suspension is much stiffer, but I only have seven grey suspensions for now. Overall, I'm happy how it came out:

    Ok, thanks. I think I got it. It's a protection for the motor. I'll study some instructions. I've seen it in the power function set 8293, that's why I asked. I have the 42065 set with two M motors, however I don't have that piece. The motors in the set are connected directly to the tracks. I'm trying to make a whish list of parts most commonly used to order them. I'll study also some steering layouts so I don't have to improvise in the future. One more question: in order to have multiple motorized functions I need more battery boxes or is there a way to connect 3 or more motors to a single battery box? For example, the one that I have its one battery box > IR receiver > and I can connect 2 motors. If, I want to add 2 more motors, I need to add another separate battery box? Because this will increase the weight of the build significantly

    what does a clutch gear do?

    Thanks Jurss! Now I'm like why I didn't think of this earlier... thing is I hardly noticed the axel holes on the sides.
  5. Un_Dac
    @Jurss, You mean to connect that piece to the axe whole on the side of the 13L rack?
  6. Un_Dac
    Yes, it works ok, you can feel very little opposing force. The rack dosen't get stuck or enithing. This is alternative 2. I used a normal beem, not a brick with holes. However, this will not be an option, first of all, the teath from the two racks do not cover evenly the beam. Second, when you turn the steering all the way, the beam will fall into the chassies. Out of all, I liked the results from the first steering system despite the parts which will slide off. I looked for an 11 stud steering rack, however for some reason, this pice dose not exist

    This is the alternative steering with the 11 stud custom rack: another downside is that the steering angle is not so wide anymore.

    I'm aware of problem no 1, however i don't have a simple solution around it for the moment. I need an 11 stud rack to use the one pice arms or I can use an 11 studs beam + 3 of simple pice racks attached to that: the down side to this is that i have to move the engine up a stud or two and will make the hole thing taller. regarding the M engine, its not that fast. I dont know if the engine is struggling or the bateries are running out.

    didn't have time to work on it, small update - finished the steering. It now has steering, independent suspension and 4WD. I don't mind that it's massive and I like how it turned out, especially those steering angles: couldn't help myself adding the motor to the chassies for a test drive. It works ok, it drives over obstacles, however, I think an XL motor will be better.

    Regarding the drive option, I plan to use the 3 selector switch and add a 4th for neutral like this: Instead of coupling the different drives, I want to uncouple the front or rear or all together: - In Neutral position the switch will uncouple the motor from the central differential and the motor will only turn the fake engine; - In center position it will couple the motor to the central differential and all wheels will turn (AWD) along with the fake engine; - in forward position, it will uncouple the front drive (the transmission between the center diff to the front diff) and only the rear wheels will turn (RWD) - in the back position, it will uncouple the rear drive (the transmission between the center diff to the rear diff) and only the front wheels will turn (FWD) the switch will be located between the seats like a gear shifter. On paper, that's the plan, but I have a long way so I'll see when I get there:)

    If I replace the pins with axels with stop at one end, will it be better? Thanks! I was actually thinking of something like that. I want to keep the 13 stud rack and replace the arms with the parts you mentioned in order get the flexibility for the suspension. I'll see. Thanks a lot! Its more fun when you don't have the exact parts and you need to improvise, it forces you to be more creative. When I started building,I was thinking "I'll see when I get there". For example, I did not know the articulations for the steering / suspension have to be just under the universal joints in order to work together. I found out the hard way, but you get this moment of "Aha!" when you figure it out.

    @Technonsense, Thanks! I had a look at that video. Also this one is interesting, however they are working with two motors and no differential. Anyway, after 3 hours of trial and error, I think I naild the front stearing and suspension, This is my porgress so far: My issues so far: - the gear rack i need for the steering has to be 11 studs. I have 13 and 8... so that's face palm no 1. The next thing I'll do I have to solve this. - the suspension I used in the above pics is not working as I expected. If you push down on the car, it will not bounce back to its initial position. If I push the car hard engough it will touch the ground with its belly and will stay that way. I changed the suspension and I got better results with these ones, however I have a hard time fitting them and the wheels will form an angle: Maybe if I add a second flexible arm behind the suspension to suport the wheel it will be better.

    Challenge accepted. Yeah, without this pice + input shaft, I imagine it will be hard to make a FWD with independent suspension and steering. But not impossible. It wont be compact though. I'm also rethinking the drive switch. I think i'll make it with only two options: N and AWD and I'll see from there later on.
  14. Un_Dac
    Ok, so i ran into truble when i started making the front stearing system. The thing is, i dont have the input shaft nor the suspension arms in order to make the articulated arms and drive axels to the wheels. So i had to find a way around it and i came up with this: https://ibb.co/ksKgEb https://ibb.co/gOhtub I had to make sure that the articulation for the drive is just over the universal joint and it works fine. We have FWD. Now I have to find a way to attache the suspenison. Question: Which is better: to have the articulation for the suspension closer to the body or closer to the wheel? And why? My guess is the closer the articulation to the center of the body => more off road capability.
  15. Un_Dac
    Thx, I'm sure I can get the independent suspension, stearing, and 4x4. I'm not sure how to make the the drive selector... Anyway, i'll build and maybe ask you guys as i go along. This is the progress so far after 30 min :) The two motors will be on the left and right side. The one that will power the drive train will be on the right and will be connected to the central differential from the sides. LE: this 100Kb limit for uploaded pictures... :( have to risize them...
