    I've found more flex usually hurts performance more than it helps. 80-90mm shocks are great for most trucks available these days.

      Yep 80-90mm is the sweet spot. All these noobs with 100-1200mm desert licker shocks crack me up!

      @josthompson7642 1-120mm anything all jacked up makes me laugh. Lizards aren't bad shocks though. They just take some time and effort to set up right. I loved them on my v3 but they were in "droop"

      90mm no less around here big rocks big dirt gotta have travel for speed smoothness and to keep momentum

      @braydenfrench8569 I've got a few comp trucks with 80-85mm shocks. They don't need massive flex to perform awesome

    I have many motors from you I bought years ago for my 2.2 Moa and shaft comp rigs ,still going strong too,many thanks 🙏🏼 good to see you still on it brother

    A basic understanding of suspension geometry is important to get the most from your RC. For crawling especially, understanding how setup affects your rig is vital. Crawling is one of those disciplines where knowledge of full size geometry directly relates to our RC cars. So, watch as many videos as you can, understand how link geometry affects handling, understand things like roll center and instant center and centre of gravity and most importantly, how settings affect each other. Learning and understanding these principles can be confusing and intimidating but the good news is, one of the most powerful tuning tools available is something we can all utilize - TESTING! The best drivers, regardless of the discipline, spend HOURS testing setups. Don't really understand how raising or lowering links affects handling? Make the change and go out and test. And keep making changes until you understand how your changes impact performance. There is NO substitution for putting in the time and hard work.

    The link riser on the Moa accomplishes planting the rig on the rock by having more leverage on the axle. To achieve planting the rig easier

    A good video to introduce the terminology and the issues with suspensions. Like you said, a lot of rambling about link geometry. You told us many times how much of an expert you're not. But you really didn't "teach" much about the topic. I'll have to dig into other sources to get guidance on what to do. But now that I'm more aware of some aspects, I'll pick and choose information sources accordingly.

    Thanks for the excellent information. I was looking into tweaking the suspension on my scx6 honcho. I added shock bands to it, and it helped a ton. Now I just gotta work on figuring out a way to adjust the link geometry,lol

    Shock weight and springs can play a huge roll in performance. I have some rigs that I run low viscosity and no springs(droop). You can achieve a very low center of gravity and use the front wheels to drag your rig over the rocks.

  • @chrisgraff2103
    @chrisgraff2103 ปีที่แล้ว +1

    Short answer i have almost no flex at all. I used a very small shock and it lowered my cg and reduced a lot of flex. This works best for me currently on my scx10 2/3 standard axle.

    My school didn't have a rocket science class, now you know why I didn't get into crawling rofl. I did though have a custom Clodbuster that had a cantilever suspension and it was awesome to see how it would work. Now can a cantilever suspension work on today's crawler? Hopefully someone can answer tat question lol. Again nice video John.

    Wrote a note to self at my work desk that says "Sloppy balls 10ii" to add to my Amain order once at home. Going to leave that post it note there to confuse the non-RC co-workers.

    I’m fairly new to the hobby, but I’m a automotive mechanic by trade. I have not done any custom off road suspension builds myself,more of an under the hood horsepower knowledge mechanic. That being said, I have a scx10 that’s all I know about it,bought it used from someone who I don’t think knew anything about it either. Anyway I’ve thrown a lot of parts at it, and the rear end is as loose as a 2 dollar whore ,from side to side movement. Just looking for some ideas or advice on what I can do to improve it?? Thanks ahead of time any is appreciated!!

    Good video, however you unfortunately have your roll centre explanation around the wrong way. The roll centre/axis is the point that the COG rotates around. A high roll centre is actually beneficial for rock crawling. If your roll centre is low (and therefore your COG is well above it) the body rolls around excessively like you shower with your yellow truck. Have a look at Busted Knuckle Off Roads video called Roll Centre Explained. Very good video explaining it all!

    • @HolmesHobbies

      I might have said it reverse by accident but that's what I tried to demonstrate with the body roll on the yellow truck. The sprung cg above roll center causes massive body roll.
