  1. Gentlemen, thank you for your answers and explaining this topic to me. Look here at Madoca's Pickup. There is a reduction in rear hubs, meaning that rear wheels get more torque than front wheels and their rotational speed is lower than front ones'. Is it compensated by the central diff? As we can see in the video, the model drives well, no slip occurs.
  2. This is how the front axle looks like. Ldd file: http://bricksafe.com/files/tomek9210/lego-technic-red-sedan-wip/rwd sedan- front axle.lxf
  3. Hello all, I have a question regarding torque distribution in all wheel drive system. Maybe someone with better knowledge could help me. I cannot build right now, so I am not able to see if it works. Let's say I would like to implement torque vectoring to the drivetrain - more torque to the rear wheels and less torque to the front ones. Am I correct that I should gear down the axle coming out from the center differential to the rear axle and gear up the axle to the front axle? Won't the wheels slip because of different rotational speed? Thank you!
  4. The gear rack may be installed either behind or front of the axle. The thing is that for front axle with front mounted rack, its pivot points should be further from the center of the vehicle, so the line leaded through this pivot point and suspended wheel pivot point reaches the centre of the rear axle. The same rule applies to the gear rack mounted behind the front axle. Look here: For steering in the rear axle, the lines leaded through steering pivot points and suspended wheel pivot points should meet in the centre of the vehicle. Ideally of course.
  5. RWD audi with mid engine. Add front drive and you have r8 But I'm waiting for the results!
  6. It may be sufficient for driving at high speeds. In case anyone was wondering how real suspension on Tesla looks like - here it is: https://www.edmunds.com/car-reviews/track-tests/2012-tesla-model-s-signature-performance-suspension-walkaround.html
  7. I think it is the first FWD car lego technic I have seen, very nice build As usual, I should add. I like your style of building. Could you please show the front axle without wheels?
  8. I agree that there might be a collision. Vertical beams with definitely reduce the steering radius.
  9. It would be more difficult to build, because top part of the famous Aston's grill is the part of the hood. If I could suggest next models - maybe a BMW M3? Or Maserati Quattroporte? Have you thought about making front axles more realistic? I mean caster, ackermann and kingpin for example?
  10. Wonderful creation! Those curved panels do the job. My only nitpick is that the hood should open the other way round I think. I am curious what will be your next build. Do you have some list of your planned projects? Do you take any suggestions ?
  11. I am quite happy with the front axle. I added another crossblock connector to support the 5.5L axle and used 6L thin liftarms to connect lower wishbone to the upper structure. It has also sway bar. It has one hard and one soft shock, but the angle of mounting them and upper links instead of one solid wishbone makes the suspension very soft. Wheel touches the soft axle and whole front of the car is less than one stud above the ground. The full shot how it looks now: For now I won't update the LXF. I want to finish this car and move to another one :) UPDATE: I changed soft front shocks for hard ones. Now the suspension is much better. I tried to implement the torsion bar, but I failed, because bottom wishbone is parallel to the vehicle. Now I will continue the body work starting from the rear doors.
  12. Almost a year after last post, I present the update :) The build was taken apart and started from scratch. My goals were to have more reliable rear suspension, stronger front suspension, v6 engine instead of R4 and realistic look (both interior and exterior) with usage of almost only technic pieces. As previous it is propelled by 2 L motors, steering by M motor - all motors have clutches, so it is RC/manual car. This was my main goal of this project. The modes are controlled by z12 bevel gears in the main console. It works very nice. HoG steering is from the dashboard. Front suspension is strengthened, it is still triple arm one - one bottom wishbone and two upper links, two shocks, ackermann steering, kingpin inclination, caster and camber. Rear suspension is Sheepo's double wishbone one - but for me it is a triple arm suspension - with two bottom arms and one upper arm. It also has two shocks. V6 engine is covered, I still have to add something to hold the cover while open. The interior is fairly detailed. Front seats backrests are adjustable, all 3 rear seats are adjustable too, the middle one have hidden armrest. The boot is pretty big. The battery box will be placed in it. The receiver is placed underneath the boot, in the place where spare tire would be placed. I have to check if it works tough :) Things left to do: - I want to have the boot cover to be opened by turning a gear. - I will try to modify the rear part to have hiding tow ball there. - Finishing the bodywork :) I loosely base on Jaguar XF.

  13. Driven front axle with virtual pivot point can be made, but the kingpin axle would be too far from the wheel's axis with 42000 rims. 8484 wheels would be a bit better here. PS. Didumos69 - I am still working on my red sedan :) I will post details later today.
  14. The imaginary intersecting point is at the outside of the wheels, which is way too much.
