|  Prevent rollback?
Any way to help with rollback when switching dig position ? Like on an incline if I want to lock or vice versa the rig will roll back a bit incurring a reverse penalty. It is an AX10 and a VP Hurtz dig. I am assuming it is the nature of the beast(a shafty) but wondering if anyone know a better way(other than moa!)

When I judge, I look to see if it's a shafty and don't count those little rollbacks as reverses. But no, I don't have any help for that question. |

Sometimes tough to time right, but I try use a small amout of throttle when using the dig.

A high quality motor like a handwound will help too or at least it did with my shafty when I had a DNA dig on it. The higher quality motors seem have better holding power.

A stronger/faster servo will help. I remember back when I had my shafty--when going from unlock/lock you get some rollback due to the nature of the DNA dig unit. Granted a faster servo helps but if the mechanical parts are not lined up internally your just going to have to adjust your driving style.

Just "the nature of the animal".  Any mechanical/geared dig/trans will go to neutral between shifts.  I guess ya could try and rig up some kind of a driveline brake with the dig servo as it goes through neutral???? Just another reason to go moa! Last edited by oldhippie; 06-03-2010 at 04:08 PM. |

As already mentioned, a faster servo will help a little. This is part of the problem of a normal ring and pinion shafty, such as an Axial. The Losi doesn't exhibit this problem due to the worm gears not allowing unpowered roll. This was the biggest reason why I retired my AX10 comp rig and went to a MOA. Quote:
Now, maybe in a local comp...especially if you have a novice or amateur class, that's not a bad idea, but if somebody is in a points series or running for a certain placement, then you're cheating the rest of the competitors by allowing guys with inferior equipment to have a pass. | |

I think you should go to your LHS and pick up a MOA setup.....   |
