How come I never see anyone making crawlers that use independent front and rear suspension? What is the logical reason behind it? Is it mainly weight transfer?

Why don't I see any independent suspension crawlers?

weight transfer. More moving parts= more problems and more tuning. The traxxas summit is an IFS crawler.... well sort of.... nah.... nevermind.
IFS crawlers in the 1:1 world work pretty well. They are very stable.
anyone have a link to Chainsaw 4X4??? :lmao:

I been thinking about building an inderpendent suspension crawler as well,maybe with a 2 speed box. Like a summit but works tho.
whole lee CHIT! I'm gunna go post a link to that in chitchat!! I'm sure no one has ever seen it

That is insane. I would love to see how he built that. Their's got to be some brilliant persont that can make an rc version of that.

IFS in 1.1 is good stock but you say everyone with a yota and a know how SAS it

Independent suspension isnt good for crawlers..
number 1: one wheel goes up on the right side, the left wheel stays the same.
on a solid axle crawler the left would go down.
Number 2: its alot harder to make them durable, axles can pop out alot easier

There's no reason it can't be done.
But seeing that there are still durability issues with relatively simple solid axles (CVD's etc.) I can't see a more complex IFS being an improvement. IFS is better for faster rigs, less unsprung weight banging around under there, but at comp speeds we won't benefit from that either. And how would you mount your battery and servo on that? Not! So with those mounted higher up in the chassis you'll probably end up with a higher C of G also. And you'll need a longer, heavier chassis to mount it. Also, due to the short half shafts, you won't get any where near as much articulation as a solid axle, and at max flex you'll have limited steering because of the combination of flex and steer angles at the CVD's.
Might be cool for scale/trail but for a comp rig there's plenty reasons not to do it, I think.
Cheers.

That thing was in Petersons 4Wheel and offroad some years back.
The guy runs and repairs heavy equipment and has a vast knowlage on hydrolics.
If I remember correctly it runs a Ford 5.0:lmao: and a single 9". that turn chain drives for the hubs. The front also extends about 12".
And for the record it realy isnt a true independet suspention."thumbsup"

I'm a stupid C U N T!
there are several good threads on IFS over Solid axle, I don't feel like searching for it but there is a nice graphic that illustrates how each axle type works and why SA is superior in crawling situations.

One of the objects to crawln is to keep as many tires on the ground as you can...IFS isn't designed for that (unless you're at high speeds, ie deseret racing)

Yeah but Ryan's on a whole different level,he can make ANYTHING work. It's not even fair......

In the 1:1 world, IFS has been tried on a comp level but it got ripped out halfway through the season and axles swapped back in. Higher center of gravity and the weight transfer is not ideal.
Going fast now, is a totally different story....
