Thanks) for all the disadvantages there are also advantages) It is simpler (fewer moving parts) and the suspension travel is longer) and this allows you to build something new, rather than stick to the classic IFS

Thanks for your thoughts ! Perhaps but its no to so critical under speed load and I think that the test shows that I-Beam is at least no worse than IFS and has the right to exist in Lego

Thank you) in my opinion, the departure angle of the IFS is slightly smaller. But if I had a Buwizz power module than a higher speed it would negate this thing.

Hi all! I built the Trophy Truck with two different front suspension setup and tested it under the same conditions. So here's a video of the test. Both trucks have the same rear and middle sections: Live axle, triangulated 4 Link , sway bar , two buggy motors, Mould King 4.0 power module, same wieght around 720gr. Now lets talk about IFS setup. Arms has narrow mounting points and “portal” wheel hubs for increased ground clearance and greater travel and reinforced by additional 6L link rods. About I-Beams I wrote all the technical characteristics in previous topics) So just few pic for references) Free instructions for both trucks: https://reb.li/m/170784 https://reb.li/m/171282 I tried to provide as fair test as possible, but my heart belongs to the I-beams, so they are better for me) Share your thoughts about winner)

will be intersting to see your design ideas on I-beams) im working on them almost one year and after your MOC i will try to figure out using the pneumatic cylinder too) So you and i will have some kind of competiton

added instructions of updated chassis

oh, thanks) my English is not so good yet Yes! i have driven version! A little later I will rebuild all the chassis with this setup and create another topic)

idk. for me the design of this suspension in real life cars is amazing. in lego its works good and its durable)if you have any advice on how to do this better I would really appreciate it!!

pretty cool design)

No. Tatra has diffent idea and pricciples of work. Performing a good jumps was main idea of this build) Thanks) There will be post about updated driven version of this suspension) Thank you)

Added video review of this truck

Yes, I agree with your first statement. In lego world its not so critical i guess. I dont notice any trouble with this while testing, but i will try to fix this in the future) And yes, I agree with your second point about the real car. I-beams for on rouad use are not the best choice. But when the beams used on dirt (as real trophy trucks do), these disadvantages are not so significant. I love the simplicity of this type of suspension and the amount of travel it can provide. I just want to show that this type of suspesion can be used in LEGO and i thik it works quite well) Thanks a lot for your answer!))

Hi all! I want to share with you my new project. This trophy truck is an evolution of my previous truck, which was discussed in the previous topic. I take some inspiration for the look from the Ford Bronco and Chevy K5, but this is not a detailed MOC. The main feature is the front I-beam suspension. The rear suspension is a 4-link live axle + anti-roll bar. For propulsion I use 2 buggy motors, PF servo for steering and MK6 module as power source.

I look forward to your feedback and thoughts about this type of suspension!

That exactly that i have done) the trcuk on 62 wheels use this kind of suspension) Maybe not so clean and "good" looking, but share same principle. Yes) thats one) fortunately they are not brea k yet) i tried make a good aligment to decrease stress on u-joints. At all it have 4 u-joints and three cv-joints
