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!

Here image with more resolution

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

i think we have a bit shiftep from topic about I-beams to the Tatra So if have any ideas how to make beams better, will be apriciated) i want to create an " ideal" set up and bring them to the world of MOC's

Thanks for this! I didn't even think about things like this

The rear suspension is looking awesome! Will wait fo the video to get more details about it!

For my TTB suspension in AWD version i used one shaft but with offseted beams - drive shaft goes between them. You can find id on the photos. And for Tatra suspension i have found solition like this, and i want to try it later.

Tatra have own unique suspension design. Adn its more for the hevy duty trucks. Twin beam suspension is more cheaper solution for the Trophy trucks in compare with A-arm builds.

Yep, agree wit that.

Thanks) Yes, looks a bit same with tatra suspension becouse camber angles. But works in a bit different way. Also you can find the footage and see how it perfoms!

Hi! Sorry for the long reply. I thinks the complex one is steering, other things , i think even more simple. Yes, the suspension changes camber and toe angles during the suspension cycle. At the ride hieght camber almost neutral , so there is no crititcal issues with traction. And yes, baloon tyres may will help a bit. Also i have added footage of the models. Hi, i have added footage with models , so you can look at them. Hi, i have added footage with models , so you can look at them.

Thanks) I keep improvig this things, so i will update them. Thank you! Wow, really strange why I didn't see your MOCs as I was trying to find any information about this lego interpretation of this suspension. If you can share any detailed pics, i will appreciate! I will look to your models more carefully.

Yep, @paave build one. This axles are pretty strong, i don't have situations where it disassembles while outdoor testing. About steering. This linkage is not steering rods , it is the radius arms . They prevent beams from moving back and forth. The steering rods postion in the front of the beams( the structture you are asked about). If hit wheel in some hard obstacle they can slide apart .But during suspension cycle and outdoor driving they holds good. I will add outdoor footage later.
