    Just to add my $0.02
    • Reliability vs. Cost - Hands down solid axles can be made reliable for less cost than an IFS system
    • Power handling - Both types of axles need a lot of upgrades to handle big power, Trust me I have both
    • Articulation - I actually give the nod to IFS (remember we're talking about RC here). My IFS wraith has more than my wraith axled 2.2 rig. It also has a wider track width. I know I could also build a solid axle rig that could have 1 axle 90* to the other. In the world of "scale" rc trail trucks and crawlers this isn't realistic though.
    • Ground Clearance - Here is the catch 22. If the IFS rig is running with both front wheels all the way down, it has a much more effective ground clearance than solid axle. But when one wheel goes up, the belly of the skid for an IFS can cause a lot more clearance issues than that on most solid axle rigs as the only thing they have are links and a driveshaft. So the most "axle" clearance goes to IFS, but the most "belly" clearance goes to solid axle.
    • Traction - Slight nod to a solid axle as articulation tends to keep the tire patch on the rocks. On dirt and mud, I'd take IFS though.
    • Handling at speed - No Brainer, it's solid axle...just kidding. IFS is better for running at speed. However you can tune a solid axle truck to handle very well.
    • Jumping - Again I prefer my IFS wraith, however I've seen plenty of guys really tune their solid axle wraith to do well here.
    Hope this helps.

    just make two trucks with identical eletronics and tires ...one full independent and one axles and 4 links ...and let the competition begin . I can see benefits in both setups .

    it was mentioned before , the reliability issue, flat out an ifs has a lot more parts that can and eventually will fail . and on a 1/1 rig these are very expensive. you have upper arms and lower a arms and their mounting points both on the knuckle and frame 3 or 4 for each of these arms, then theres the cvs which are not known for being able to take a hard beating b4 they break and you have 2 of these for each side per axle. although there are exceptions. imho theres just too much that can go wrong with ifs in a hard core situation. solid axles are used for nearly all heavy duty applications ,so a strong beefy axle is easy to get . they have only a few moving parts at the knuckles and most use a universal joint at the steering parts are cheap and even stock parts are strong and can handle a lot of abuse b4 breaking and if you can weld you can build a beast of an axle using parts from other axles. now everything ive said is more true for 1/1 axles than in the rc world

    I thought you were kidding around, lol.

    I've never seen an FJ that could hold a candle to any solid axle Jeep in any situation...ever, less on road ride comfort.

    I agree the fj is a great trail truck and its a shame its been discontinued. ive seen them do things stock that was amazed me, but to blame it all on Toyotas lack of advertising, sorry I don't buy it. I was reading some reviews earlier and the main reason I saw in those reviews for a lower rating was its lack of on road ability, that it had no power at highway speeds and felt sluggish when passing or going uphill. basically they said Toyota put to much emphasis on the yjs off road ability. still id like to have one of my own.

    You guys crack me up. My guess on the straight axle in real life vehicles is because they are all basically willy's jeeps and Dana still rules the 4x4 world. Just a guess.

    Ready for this? Im gonna tear your fj down, first this video any stock ass 4wd vehicle can do this the rocks are super grippy and its not that technical hell full size dodge rams have made it though here.

    Now this one, yea the fj made it further well duh he has more power and speed over that short little distance then that MANUAL little samurai did. My big ass fullsize dodge has made it up stuff bigger and steeper then this.

    A jeep will out wheel damn near anything simply due to its short wheel base and very easily modified and wide abundance of parts available for it.

    My dad is an engineer and he said straight out , and I completely believe him , that straight axles are for durability and IFS's are for comfort and turning

    No it's fine, I'm just glad it's bringing a reasonable discussion. I like hearing people's thoughts on things. lol So no worries, highjack away. And solid axles also keep the wheels in line with each other, as compared to ifs which usually, I assume, have CV joints that take more wear and what not when being the flexed and what not. Or something like that. lol
