| my sticky dig.... help
I'm not exactly sure what's going on, so I thought I'd throw this thread up to get some ideas before I tear into this thing tonight. oh the mechanical dig woes My dig will shift out of 4wd into 2wd or lock perfectly. The problem is getting it back to 4wd or 2wd out of lock when the back wheels are bound up. I'm pretty sure this has all to do with my servo being chassis mounted. Then again sometimes I think this is electronics related. I can be sitting there with the rear end flexed in lock. I will shift into 4wd and I will have to rock the throttle back and forth to get it to engage. DNA dig w/JR 126mg 126oz servo JR 8711 for steering all hooked into a y harness to run off of my CC BEC. (6.0) other electronics are DX3 w/sr3000 1250 3s 10c lipo Last edited by helhedded; 06-04-2009 at 02:50 PM. |

How freely does it operate by hand? Do you have any noticeable slop/flex in your servo mount? Can you post a few other angles of your linkage? Have you checked operation without the linkage hooked to the dig to make sure the servo consistently operates as it should? Is it possible your rear male drive shaft is a bit long and is getting stuck inside the female shaft when in dig? That could make it hang up and require tweaking to get it back out of dig. We'll get to the bottom of it with ya...one way or the other.I still run mine on the original 225MG from my first VF test dig unit with no issues so I am sure we can get it figured out. Don |

Have you replaced the driveshaft? If they are old & rocked up you may need to replace them so they slide easy.
