  1. camber would let the car corner better as the bodywork would lean into the turn.
  2. Yes it's definitely a major improvement on the original setup and yes these can be built really solid and tough. 2 studs of caster is quite alot. I think 1 stud would have been enough as is. 2 yellow shocks are pretty stiff. I'm sure with 2 gray shocks you'll get more stiffness compared to just one yellow shock and not have issues of the parts not being able to handle the extra hard stiffness. Kingpin, caster and ackerman will definitely improve steering and reduce stress to the steering servo by a lot. Make sure the CV joints can handle the extreme steering angles. I think that U joints still would be fine with this. I would experiment with 0,5 stud camber. to increase cornering efficiency.
  3. You should visit @nicjasno's discord server and discover the wonders of lego technic geometry. Here's an example of radical geometry for a drift car: It has: -Kingpin inclination (helps with return to center steering. Great for heavier mocs to reduce stress on servo) -1 stud of caster angle (Increasing the amount of positive caster will increase steering effort and straight line tracking, as well as improve high speed stability and cornering effectiveness. Positive caster also increases tire lean when cornering (almost like having more negative camber) as the steering angle is increased.) -Negative camber (Camber angle alters the handling qualities of a particular suspension design; in particular, negative camber improves grip when cornering especially with a short long arm suspension.) -Ackerman steering (Better performance when turning. Your steering angle will improve.) You can get ackerman steeringsimply by moving the connection point of the steering link by 1 stud more closer to the chassis from the pivot point of the wheel hub's connection point. Camber can be achieved by moving the upper control arm by 0,5 studs closer to the chassis than the lower control arm. Caster can be achieved by moving the upper control arm back by 0,5-1 studs or moving the lower control arm forward by 0,5-1 studs. Kingpin inlcination is a bit trickier. You'll need to build a wheel hub in a way that the upper control arm's mounting point is one stud closer to the chassis than the lower control arm but still having the hub straight.
  4. Please give this front axle some proper geometry. At least caster angle and ackermann steering.
  5. Front axle for a model T style'd car. The springs can be changed into a leafspring. The sliding mechanism is there to give you more ground clearance. As the axle moves up, the triangulated control arms will slide back. The triangulation will keep the axle from moving sideways. Playing around with the springs will give you huge flex on the chassis. Sadly no drive in this axle. Only steered. EDIT: Use 7 long axle for the sliding part instead of 6 long axle.
  6. I'd love to see this with power functions instead. Is it possible?
  7. Flex axles have been used for a "leaf spring" in many mocs. I'd love to see lego design a real leaf spring for lego. Perhaps even different sized leaf springs. They certainly would be used for many trucks and classic muscle cars.
  8. Magnificent moc at this scale. Although i'd love to see a larger tatra build with the suspension being pivoted by a different point than the drive axle. That way the drive axle is not stressed with friction and weight of the moc.

    Even with reduced steering angle, you'll still be able to drift due to the high power spike.
  10. change the diffs to the older style and you gain more speed.
  11. Too bad that the original doms charger front axle is garbage. It has zero geometry.

    Change to normal hubs instead of planetary hubs and it'll be like 10 times faster.
  13. WIP Features: Front axle: Kingpin inclination, caster, ackerman. Engine: Fake engine that has moving pistons. Bodywork: modified with pickup style exterior, better suspension for offroading. Note: The whole chassis is currently just supported by random beams giving it's shape. It can't really stand on it's own yet due to the whole chassis bending so it's currently sitting on top of 5x7 frames so the bodywork and chassis doesn't get bent. To do list: Motors and gearbox. Rear axle Complete the chassis Touch ups on the enginebay. Mount spare tires behind the cockpit. Add guns. Test drive.
  14. you could build a ford transit body on top of it.
  15. i agree with this. We need to figure this thing out. And probably have an experienced builder do some quality control. Perhaps if this is too late already, make a completely new axle collection thread which just has pictures or links to axles we can build with information like width or size or what features they have. That way it would be very easy to search for something useful.
  16. Somebody should take the time and effort to categorize each axle on this build thread into groups. I suggest groups by size so it's easy to check for a certain width axle for a certain build size quickly. Each group should have links to the axles in this thread. This should be edited into the first post. This would make it easier to look for certain axles instead of reading +29 pages of this thread.
  17. Tbh people underestimate how tough a technic chassis can actually be with correct geometry. All you need to do is make sure this thing is as hollow as possible. Do not use unnecessary parts. Try to make an extremely stiff chassis with as little parts as possible.
  18. There's my front end of the bodywork.. Now i need to figure out a 15 studs between tires front axle (i will be using arocs tires.) That has proper geometry. Caster and ackermann definitely.. Perhaps kingpin inclination and camber
  19. it's a moc that screams mad max mods. I want to build it with the mercedes arocs tires. Having single tires at front and duals at the back.. Body might need widening. But i really want to see a pick up style rocket spears setup at the back like in madmax fury road.
  20. I'd love to see more mods on this set. Perhaps a madmax style build. Gotta rebuild the charger at some point and try and fiddle with it. One thing i would change is the garbage suspension system and actually give it caster and camber.
  21. Man! Why haven't i seen this moc before. This is awesome! Can't believe i missed this for so long.
  22. That's awesome! Thanks for sharing the instructions!
