|  What servo for an R2D II?
Just ordered up the new R2D II from RC4WD. Just wondering what servo I should get to operate the dig? Will a 645mg be sufficient?

That will work fine but in would put in the highest torque servo you can afford. Mechanical digs need high torque to work effectively in a bind situation. | |

A 645mg should be more than enough. I was running a 33 oz. servo for my R2D. And the only time I had an issue was, if I was in front wheel/rear locked and dragging the rear down a slope. I could not get it to unlock till I got to the bottom.  |

When I had a R2D I used a 645mg and it worked perfectly.

ACE makes great servos as well with loads of torq.

645 should work fine. With the new dig sleeves the R2D II shift so much smoother.

Ace does make a great servo but way pricey for what you need. I'm not a fan of hitecs at all. But a Hitec 645 will be all you need. You don't even need to go to the 5645. You could probably even get away with a 625. |
