    I was wondering why a solid axle is better for crawling, then independent. It can't be for the diffs, cause you can lock independent too. The only thing I could think of was for the scale feature, or the articulation? If someone could explain this, it would be very helpful. Thanks.

    Strength. As of to date, there are no 1:1 or 1:10 independent setups that can keep up with a good ole solid axle design when you start pushing extreme power to them. To break it down further, there are more parts to break on an independent system...and break they will.

    Independent setups are superior, in every way...except for strength...dealing with power.

    Look at that itty bitty axle shaft in the front, lol. I think it comes down to power changing directions too many times in an independent setup. All I'm saying, is if IFS was a strong as a solid axle, every rock crawler and FOFFer would be running it. :)

    I should add, there are different forces at play on any given situation. A dune buggy or similar vehicle darting across the desert has independent suspension...at least in the front. These vehicles have lots of power (horsepower), but it's applied against sand and loose terrain. That terrain gives a bit. Wheel speed is key here, and independent suspension works wonderfully.

    Now take a rock crawler, it also has lot's of power (torque)..but it's applied differently. It's power is against large rocks and other "immovable" terrain. This terrain doesn't give...any. Here, in this situation the gearing and metal shafts must be more powerful than the force applied by the tire friction against to rocks.

    It's the difference of punching a light object, verses shoving a heavy object. Hope that makes some sense.

    Color me impressed!

    I love "arguing" with you, lol.


    Anyways, I'm about to buy some stock in RC IFS suspension parts...'cause y'all be buying a lot of them! :)

    i would think that axles would help with keeping weight low ... in crawling every ounce counts

    i heard torque and horse[power refered to it this way once

    horsepower=how fast you hit the wall
    torque=how far you move it

    You all know I love debates... There have been 500+HP tuners Drag Racing with front wheel drive only, for years and years now...

    Perfect!

    I've has blown 'Stangs, boosted Mazdas, and stroked Jeeps...I love them all.

    (You know damn well a solid axle is stronger)

    you guys are forgetting the biggest thing.... articulation. solid axle allows the wheel to travel further in relation to the wheel on the opposite side of the axle, and also keeps the contact patch of the tire parallel with the axle, which is usually in line with the surface you are on. its all about traction and torque in the game of wheeling. also, when IFS compresses, the pumpkin gets closer to the ground. solid axle the pumpkin is always the same distance from the ground. ifs is good for speed based racing due to wheels moving indepentantly of each other allowing the body of the vehicle (ergo the main mass) to travel in as straight/flat a line as possible.

    My stock jeep got as much flex as that h2's modified ifs if not more.

    Also, the axles are more likely to bind in an ifs system. Cv's only bend so much. In a solid axle design all your driveline is kept mostly straight (steering aside) and your pinion angle doesn't change all too much

    And what's more, the rear axle is doing the greater part of the flexing in that h2 pic. Can't compare to an h1 either which was independent on all four corners
