Not sure what your getting at. ARB locker could be concidered a part time locker. Twin sticks in my Toyota I can get double low rear wheel drive only. Atlas II can as well. I don't care about the real deal,thats not what we're building here. I want to see a RC crawler with REAR dig. Quote:
I needed a weak link in my super so I used an Emaxx spur. Cheap,easy to get,easy to fix under a time limit and pleantyfull.

Any of the Clods with two ESCs on seperate channels. Or when mine is done, two switches on one servo. Push right it does front, push left it does rear. |

Rear dig might be helpful to kick the rear end around if you had 4WS (but not comp legal, at least in 2.2 anyway). But yeah, I see what you are getting at with this new "rear" dig craze  |

Front dig is disconnecting the power to the rear axle,in the transfercase or through a driveline disconnenct,not unlocking the differential. Then apply a brake on one or both tires on the rear axle. After thats done,turn the tires the direction you wanna go,drop the hammer and let them front tires eat. Although running an ARB diff in the rear unlocked while doing a front burn,it'll work better since the outside tire will be free to roll. Can someone show me a rig with REAR dig please? | |

I'm talking about real RC crawlers here. Not your robot type thingymabobs. When I see a 1:1 crawler at the comps with a V6 and a 10 gallon fuel cell hanging on the front axle,I'll then concider a Clod to be cool. | |

So would you still consider a Clod cool if I showed you a 1:1 with a V6 on the "rear" axle instead of the front? Here's Jennifer Little's half version of a Clod crawler. (in case pirate doesn't allow linking of photos: http://www2.pirate4x4.com/albums/album45/aha.jpg ) Oh, and I should have F&R dig on my "TINY" project. It will be a while though. Sorry about that in case you really need it now. -Sam | |

rear dig is the same as front dig but in order for it to be able to do anything you need rear steer

Rear Dig? If you wanna two wheel you should buy a beetle chassis for your beetle body.  Rear Dig! Rear Dig! What did you do to produce that avitar raptor man? Bind the tires and run the slipper much??  I did that on my 16.8v dual 750 motored Maxx geared high tryin to crawl it.... Realized my mistake of running the slipper too much and never did it again. You must have had to work at it to make a geared down crawler do that. I ran a 3025 @14.4v... even though it made more power then most, the motor did not do it, it was driving style. I could take a stock e-maxx and produce the same gear. Its a waste of power. PUT IT TO THE GROUND! Not the slipper. |

WTF, First "rear dig" will work without rear steer even though it doesn't matter since anyone with a super and "rear dig" will have it. ( a sliight sidehill is all that is needed for rear dig to work) Of course it will work better with rear steer, but point is in the right situation it will work either way. As for a picture, you should be able to see it in your head since a super if done right could be driven either direction anyway. So ideally depending on which direction your going your "front or rear dig" would change anyway. ANother way to see it..........think of a 2wd truck with the front brakes locked up I don't understand why you need a picture?! Example: At and event they had two super gates that needed a 17 or shorter wheelbase and rearsteer to make the turn without a reverse. There was an 18(king bling) inch super that made the turn by engaging "rear dig" which in turn braked the front axle, this allowed him to rear steer and throttle effectivly pivoting him around the turn. Long truck made turn without backing up. Example: fronts against a ledge, rear of vehicle really needs to be over 6 inches. This would not be possible rearsteering since front might climb ledge. Rear dig would allow you to pivot the rear over before attempting the climb(saving a reverse) |

I think what Raptorman is getting at is that people keep referring to "rear dig" when they really mean front dig. I have seen it in a bunch of posts too. Last edited by Grizzly4x4; 07-09-2007 at 11:58 AM. |

I did that with my super running the 3025-8 on 10 cells at 55:1 gearing. Can't really say I'm geared down,it'll spin the XL's pretty good compaired to most crawlers. Didn't really work it much. Just had wore out slipper pads and they just got hot near the end of the run. Then,the spur started smoking......then,it egg shaped itself and I stopped moving I'm currently waiting on parts to build a better slipper set up so it'll be better. Quote:
I'm fully aware of what dig is,front or rear. I'm also fully aware of the fact that you need the tires on the driven axle to turn left to right to be able to take full effect of the dig. Just got tired of reading about rear dig when I knbew it was front dig they were talking about. Just trying to get some minds a thinking | ||
