Re: My Bruder excavator w/screwdrives
That looks amazing, a thumb would make moving that stuff alot easier. The boom looks very solid and i love the lights mounted on the sides like that , i may have to get a set from you.

Re: My Bruder excavator w/screwdrives
Well,decided to make another boom for the Bruder,,like the servo further in the boom,seems to work better.Yea,thats a bucket pin from a real excavator for the counterweight on the door on my grill,last pic,LOL
Also uped the battery from 7.2/1800 mah to 3500 mah , running a Hitech 755mg servo in the boom. Last edited by pumptech; 10-21-2011 at 08:11 AM. |

Re: My Bruder excavator w/screwdrives
I'm trying to figure out the time line on your Bruder conversion. Is it about two years old now? Is it working good? Any maintenance issues or things you like or dislike?
Thanks, Jim |

Re: My Bruder excavator w/screwdrives
Hey Jim ,I started this conversion ,January 2011 , during the beginning of the build/conversion was finding the right high torque metal gear servos ,using different torque ratings on parts of the build. Highest torque needed for the boom and stick .One dislike I had was in the beginning ,needed more lifting power at the boom ,decided to redo the main boom ,using a 1/4 scale hitech755 mg there ,has good lifting power now ,changed to a 2.4 ghz transmitter from the 72 mhz no glitches now !! Have had good luck with the servos ,havn't fried one yet ..As of now and last year or so ,not much maintenance issues ,just charge up the battery and go

Re: My Bruder excavator w/screwdrives
Well decided to put the bruder excavator back on the workbench, nothing was wrong with it still running fine, wanted to experiment with a new style boom.In the process of building a new boom based off a pic I found of a demolition excavator .Also building a new arm with a thumb attachment , still have a lot of work to do on it, have a couple of pics so far , will get a test vid up soon

Re: My Bruder excavator w/screwdrives
I am using 1/4" masonary auger bits ,found at any hardware store ,wood auger bits will work also ,incased in 3/8" SST tubing with two set screws to travel in the valleys of the bit.
Here's my build thread over at scale 4x4 ,have tweaked it a little since then ,but basically still the same method. http://www.scale4x4rc.org/forums/showthread.php?t=56870 Been working on the excavator a little here and there ,will get a update soon.
