|  HG645MG Servo
I've seen this servo mentioned a few times around the board for a decent budget MG servo. Well, I just happened to have one in my toolbox and would like to get it mounted on my MRC. Questions: 1) Mounting. I mounted it decent enough with one screw and some zipties but I was looking at this mounting plate by RCBros. Anyone have any experience with it? 2) The splines are different between the HG645MG and the servo saver. I've seen people run a straight linkage without the servo saver. Are there any drawbacks to that since the servo has metal gears? Is there a servo saver that is recommended for use in this situation? 3) Yes, I've seen the BEC thread where YOU NEED A BEC is spammed all over. What I didn't see was any reason (i.e. current draw, etc.) besides some people saying yes and others no. Do I need one for recreational crawling with the HG645MG? Thanks for any suggestions! note: I posted the same thread a bit ago and it got held for moderation. I still haven't seen it but if it shows up at some point, I guess it can be deleted. |

You really want to 4 link your MRC and that plate doesn't allow it. No need to run a servo saver on a crawler with a decent servo. The 645 has plenty of power. You may or may not need a BEC. What are your plans for your Pro? Couch crawling, backyard bashing, comps? Quote:

Are there any easy 'kits' for four-linking the MRC or are they all hack jobs? | |

Basically any chassis kit will provide you with what you need. The GC3 is cheap and will provide you everything you need. There are other kits, so check those out as well. Quote:

Rcbros makes a 4 link servo mount and I just made my own links. I run a bec but if you wire the servo right to the battery I have heard you don't need one. Hope this helps

Does the MRC Pro need modifications to have a full sized servo installed?

The Pro servo plate has two holes for one of the towers so you can just move it over to fit the std servo. | |

Good call if you got one of the last cheap ones. They're all but gone now.
