That is correct - preload is not going to help with torque twist. Stiffer springs with low preload would be the correct approach. If you have no springs, you still have the weight of the axle and chassis pushing down on the tires for traction. Adding springs won't increase your down force - you can't create any more down force than the weight of your car (unless you are moving fast and add wings lol). Springs will help to smooth things out and maintain more consistent contact, but not add more force. 80-90% droop, very light springs with high preload is a nice place to be for most people. If you are climbing super steep stuff all the time, full droop with negative springs might be your preference.

I love that!

You are welcome!

Thanks again!

Thank you!

Thanks for saying that. I debated whether or not it was of interest.

@@BoomslangSuss I, for one, appreciate the journey. Just the ultimate result does little justice to the trials along the way

Thanks! Even better version coming 😎

Soft tires and soft inserts. Lower the ride height. Add weight to the front to get a 60-65% forward weight bias - add it as low as possible like at the steering knuckle. Remove weight from other places. Not sure if this is possible on your setup but switch to a front Servo-on-Axle design. If you really want to go crazy, try Loaded Dice wheels and weight hangers from Dlux. So many things are possible!

@@BoomslangSuss Thank you! I just recently bought a brass steering knuckle and jconcept tusks. Also, do you think having the most weight possible below is better?

@@lucaqdjncs You actually want to keep your total weight on the lighter side where you can. Don't just add weight to add weight. It's best to move parts forward and down, or buy lighter parts first. THEN add weight if needed to get the front weight bias. Any added weight should be as low and forward as possible.

@@BoomslangSuss Alright, thank you!

I sure do! Had a few Profile Racing cranks myself.

If you have over/under drive one set of wheels has to be slipping. If the rear has grip, you are right, AS will be actuated. However, most crawlers have a forward weight bias and the rear wheels are slipping. This is what is demonstrated in the video. As you start to go up hill, your weight bias naturally shifts to the rear and you start to get more traction in the rear as you point out. Also remember, AS is a dynamic response to a dynamic weight shift. If you are crawling at a slow speed AS doesn't do anything. I published a couple videos on that topic.

No, but you need acceleration to activate anti-squat. It's a dynamic response to a dynamic weight shift. AS has nothing to do with wheel torque.

It's all explained here. ruclips.net/video/-ad04wUd8PQ/видео.html

@BoomslangSuss you are very wrong, anti squat has everything to do with torque as its a direct relation be the tire rotation and since antisquat works on axle rotation putting pressure on the suspension through the links.. also anti dive is another thing, don't be upset with comments just go read a bit more and test properly, if you were to have the truck held back with straps and throttled in place with a high anti squat ratio you'd still pick that rear end up as soon as it starts putting torque to the ground..

@@theoalbert897 I've read every document ever published on the topic and written a few of my own and was professionally paid for my knowledge on AS for 30 years. If you watch ALL the videos it's clearly explained and demonstrated.

I would like to but probably not this year.

I’m working on spring rate, oil weight and a full droop tuning guide which no one has done to my knowledge. Stay tuned.

@BoomslangSuss nope that's why I'm asking tx

I have 2 SCX24 as well. Great for family and friends.

Thanks! Always evolving.

Thanks!

Think of it this way - your rig will travel forward slightly slower than the front wheel speed. This is because the rear wheels are putting on the brakes, just a little, so it prevents the car from driving at the full speed of the faster turning front wheels. So do you want your rig to have faster or slower forward speed? If you want slower, underdrive the rear. If you want faster, overdrive the front. Personally, I gear down everywhere possible - I run 4S and want it to creep as slowly as possible. Better slow speed control, longer battery life, higher torque. Mechanically, it doesn't really matter if you change the front or rear. Pick the one that moves your overall speed in the direction you want.

Smart people there.

More to come!

No, not that into them, but would love to hear why you like them.

@@BoomslangSuss Ran across them recently when their drummer was on Drumeo. Pretty good. Not exactly metal but it sounds good cranked up in my truck.🤙

@@redrustbucket I'll check that out. Thanks! I love discovering new bands.

That was my thinking as well, but proved very tough to hit the timing just right. More practice I guess because that could look super smooth.

Thanks!

My final samples of the knuckle weights are arriving soon. Lower CG than Loaded Dice and fit many standard beadlock wheels.

2.2 tires. I run wide rims, in this case 1.5 Crawler Innovations plastic wheels - wide, light, cheap and I've never had one fail yet. Have to glue them though. Wider rims support the sidewalls better and reduce the tire folding over sideways.

@@BoomslangSuss I’ve seen those rims on CI website. I run CI foams on all my rigs. That is a wide rim. What is your ride width? Outside tire edge to outside? At least 11”? What tires are those? IBEX?

Yes, Proline Ibex. It’s pretty close to 11” outside to outside.

@@BoomslangSuss Thank you! Great videos and information. Keep up the great work! Appreciate the feedback

@@BoomslangSuss wanted to ask you another question. What are you using to cut your carbon fiber pieces/chassis?

Thanks!

Thank you. Not as easy as it looks.

@@BoomslangSuss oh believe me I know.

@@DubVredneck😂

@@BoomslangSuss 😁

Thank you.

You're very welcome!

Nice.

I’m working on a few videos about negative springs and oil weight. You consider 60 weight a lighter wt?

What do I have to gain from throwing the test? Besides, the test was done “blind” so I didn’t know which was which. Try it yourself.

Sounds like the Kyosho has a RE-gressive setup - rarely ever a benefit on any vehicle.

Yes. It starts out as progressive but passes 90 degrees and becomes regressive. I’m looking into ways to fix that as I don’t mind not being ”period correct” and you could have done the same thing in the ’80s if you understood geometry.

Yes, I recently took off my springs entirely front and rear. The axles have high weight relative to the chassis so there’s no problem getting full articulation without the help of any springs so I’m really liking this set up.

@BoomslangSuss hay your in the bay area ? Do you get out to the bean ? I would love to crawl with you I would like to see how your rigs do there's a group going the assilamar in Monterey Saturday the 13th

I've been to Bean Hollow but it's a little far from my house. I might be down for Assilimar.

Well, my pants thank you, sir

Thanks for the heads up! Looks like Amazon doesn't have it any longer so I added an A*Main Hobbies link. It's a great little charger. Thanks again.

The Rhino used to be a really cool car, but it’s fallen behind a little and is not that popular currently. Carbon rail chassis like Poizd, G-Speed, Corrupt Carbon are all designed by people who are much closer to the current crawling sport. It’s easier to build those chassis into a legal competition class if you care about that. And there are a lot more aftermarket parts available. But they are all custom ground up builds and the rhino at least gives you a high clearance rig right out of the box as a starting point.

@@BoomslangSuss tha nk you very much for they great information on the truth behind the anti squat and the way u explain the overdrive and when it actually works u couldn't of explained it better more people should listen to what u have to say again great information THANKS.. after watching your vid i got online and searched for poizd chassis kits capra poizd and i cant find where to buy one from there,s a few vid,s on people with poizd capra,s but again no mention,s where u can purchase them. again if u have the time could u spear me in the right direction please thanks again Aussie jas

Try asking Travis Rake in this forum how to purchase in Australia.

Agreed - the rear wheel weighted was not going to show a difference, which is my point exactly. You can't push the front wheel down under any circumstance, which is what many people believe. If I were to decrease the incline by 1/2 degree, the car without a link riser would climb it, which is why I selected that angle. If the link riser made a difference, it would have shown up at this angle.

haha

It depends first and foremost on having sufficient acceleration to create a dynamic weight shift. AS is a dynamic response to a dynamic situation. If you are slow creeping at a constant speed, your AS number means nothing.

@@BoomslangSuss I’m talking about slow crawling the same line with the same vehicle and the riser being the only change. All other variables exactly the same. The only other change that happened was the axle position due to adding a riser and not adjusting link length. I’m not saying anti squat magically worked without acceleration I’m saying the addition of a riser and nothing else made a difference sometimes.

Well, there are not physics to support that. People don't like to hear this, but usually their vehicles are not as "identical" as they think, and it's really tough to get repeatable results on real terrain that meet scientific rigor. Try double blind testing and see if you get the same results - have someone else set your link riser without telling you. Run it multiple times. At least 3 times, but 10 would be better. Then let someone else drive your vehicle and don't tell them which setting they are in. When you start to add this statistical relevance I think you will find that you cannot tell a difference with and without a riser. There is simply no physical mechanism at slow speeds that could make a difference. Or, ignore this altogether and just go drive and have fun! Thanks for watching the video and sharing your thoughts.

@@BoomslangSuss you can’t get more identical than failing to climb and going in your bag on the trail grabbing a riser and installing it then repeatedly making the same climb.

@@covecityboys So you practiced and got better. That's not statistically valid. Double blind and multiple runs with different drivers is the only way to eliminate the driver as a variable. I'm telling you friend, no suspension engineer would agree that link risers work as you describe. There are simply no physics that support that, which means it's something else, like driver influence. No offense intended toward your diving skill - you are simply not driving the same in your trials. I suspect you won't waste your time on a blind testing method, which I why I did it for you. Link risers don't work on paper or in controlled testing.

You bet!

I’m at 35% and thinking about reducing it. Unfortunately 25% is the next possible step down. I’d like to be at 30%.

​@@BoomslangSussI have no idea why it posted under this video....I guess it moved to the next video and I didn't notice...🤣😂

@@mgoo1713 I was wondering, hahahahh

You bet. Many concepts need examples because they are so often misunderstood. I’m trying to make it clear and simple. Oil weight selection is up next - that will be tricky.

But how much is too much ? 🤣

You’ll know when you start breaking axles

@@joseywilds3133 lol

Agree! One of my favorites. They just finished their new album. Hopefully we’ll hear it soon.

@@BoomslangSuss I am lucky to be friends with Max (their producer/sound engineer). Such a good guy. I am sure he'll produce another piece of metal art with Jinjer. Waiting impatiently!

@@DupdopyThat’s random! Do you have connections to Ukraine?

​@@BoomslangSuss Not really. I worked/work with different musicians/producers around the world throughout the years (music software project). Met Max at some point. The rest is history =) He is an amazing person.

@@Dupdopy Nice.

Never hurts!

Thank you! I felt there was an opportunity for better science with RC crawlers so I’m trying to offer it. I’ve got a lot more to come.

Thanks!
