It was a local guy in the cab,hired him on from labor finders

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.

Thanks bigpipespete
Yea,a thumb would sure work nice with the loose material.
will see how it fairs ditch digging next time.
I found those lights at walmart in the automotive accessory section.12 volt led,2 per pack.

Made a stiff arm thumb for the excavator,only running 6 channels had to go this route,it works good.

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.

Hey pumptech any chance you can show some close up pics of how you attached the servo to the track gears?

cheers

Hey Igotit ,slip ring has been in it for awhile now ,guess I should have taken a couple of pics showing installing it ,its the same as yours ,fun part was heat shrinking all the wires lol !! really don't see the use in filming it doing 360's for 5 min.lol!!

im assuming it works well then...I was afraid 2 amp draw per wire would be enough on long travel trips.
glad to see its working out.

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

What screw drives are you using?

[Lil Giants]

Smooth movement, much better than previous screwdrives.

[Exclusive RC]

Very clean, swift movement, which screwdrives did you go with?

Thanks. , using all masonry bit except for the thumb using a 1/4 bolt ,slower movement , but plenty of power on the thumb

[pumptech]
