This guy's logic is illogical

[yoothgeye]

Please watch this video and tell me if you agree. People seem to be taking him at his word. He has equipped his RC crawler with a dig box, the dig gear box uses an extra servo to lock the rear shaft so that the wheels don't turn and allow the front to pull the vehicle around using the back wheels as the pivot point. This guy has concocted some rear suspension that he says helps it to get a "deep dig" by allowing the rear axle to twist downward during a dig... wait a minute, aren't tires round? What does it matter what angle the axle is at?

Watch and tell me if you agree with me or him:

OK. I understand what you are saying. but Honestly, I think RC cars are cool, but is there a point where too much is too much?

the only advantage I can see is the rig squats for a lower center of gravity, and it does and the straightened drive line will be stronger as it tries to keep the wheels from turning.  But he did not address either of these.  My vote: idiot!

I think he broke a link with that dig set up.....had a few spare shocks......put em in......made up the story to sound smart.......

Looks like a great way to break the tiny driveshaft,if you look closely it clamps onto the driveshaft to keep the rear axle from turning.

:\ not a good setup in my opinion.

just my 2cents.

[madbob]

since RC cars don't have brakes at the wheels you have to use the drive lines to keep the wheels from turning.  This setup is so he can negotiate sharp corners to set up for the right line in competitions, and avoid the penalty for backing up.

Yeah, I'm not disputing the "Dig" t-case, it doesn't just lock the rear driveshaft, it first disables the rear drive. I am disputing his "deep dig" theory that the rear suspension tucking down under the load causes it to dig in more.

[madbob]

las comment was more directed at dylan.  the rolling of the rear axle may allow the tire to grip rocks better for the first 1/4" or so, butI don't think it creates the "deep dig" like he tries to describe it.

I've had a few comp rig's i luv the dig units but dont agree with that deep dig crap. because i've been on some sand and the rear just follows you around. the proper way to use the dig is to lock it and just pop the throttle a few time's  to make it bounce when it  turns because it's easier on the tire's and the the drive train.

[yoothgeye]

Thank you! Exactly.

wouldn't making it squat harder change the lenghth of the drivetrain?  If you could controll the squat I guess you could change the distance you dig, but it should be very minimal.
