    (Sorry for mistakes (I'm not from Britain / America)) I was thinking about LSD (Limited Slip Differential) in lego. Because all I saw yet were just differentials with locking mechanism that engages after few turns of axle. And only thing it was limitting was main function of differential. So I came out with this solution - I know it isn't great, but it is very simple and compact (actually you add one rubber band inside differential (under spider gear)). What that does ? - When axles want to spin at different speeds (while cornering) more power is required (so you lose some speed if you don't have powferful motor) but, if one wheel lose traction the other one gets more power (compared to open differential) and you can also set how much additional friction you wat (by adding different number of rubber bands inside). Here is one picture of it : https://imgur.com/a/JTjgdBn I just want to know what do you think about it, and if there is possibility to create a real LSD in lego.

    Now I randomly found few pictures of that car in my phone , so I'm going to upload it here (but I took that photo for presentation of RPM meter that I made) so it's not ideal (those motors in the front are just for stopping car from moving forward) Here is that photo : https://imgur.com/a/AbR9D Yes, and also it is pretty old photo because it was prototype 1 (just for testing spring hardness and RPMs of wheels motors etc.

    I'm afraid we don't have these parts. Because we only have NXT and EV3 (we don't have PF) and also we only have older differential , but I guess I can do that work even without those parts. And that baja truck and 42075 rear axles are pretty similar (but i probably take more inspiration from 42075 set, because it looks lighter and more simple). Thank you very much guys :)

    I was also thinking about that, but on the track there are lot of turns so the car is going to have little side to side movement (i want to use sabilizer (or sway bar) in it so it is not going to roll over)

    If you aren't going to drive just on dirt you shold try to put differential there. It will make driving on for example tarmac lot more siple and easier.

    (sorry for my bad english) I'm thinking which suspension type should I use for my race car. I'm doing it outta LEGO Mindstorms (NXT/EV3). It's suposed to be RWD (with differencial) car for racing on flat surface. But on the the track the is one jump - it has 15 cm (or 5.9 inch). And I need suspension that is going to be light, kinda robust (it has to survive fall from 15 cm (5.9 inch) and also simple. I was using multilink suspension in the back and something like McPherson in the front, but it didn't worked as i wanted. So I'm thinking about using still multilink in the back, but double wishbone suspension in the front. (I'm using soft springs because car weights 850 g (or 1.87 lbs)). What do you thing is it allright or should I change it, or are there some bad sites of this two types of suspension ?
