Ultimate 8043 Motorized Excavator
Ok, this isn't a MOC, but I did some heavy upgrading to the 8043 motorized excavator which is definately worth mentioning
It is a very nice model, but there were some things I wasn't happy with:
* Lifting
the boom was underpowered
* It used normal batteries
* Bucket was too big, doesn't
have a correct rotation point and it's working range is too small
* Working range
of the dipper was too small
* Side-effects of "2 drivetrains throug a turntable" were
too noticable
* Not all the functions were available simultaniously, switching is
neccecary. Moving the boom/dipper/bucket was not possible during rotating.
All this
together made it quite a poor digging machine. This could be done better...
So I started
rebuilding the model. Now it includes:
* Full independent simultanious controll of
all the functions
* Joystick-controller that works just like a real excavator. Based
on a desigh by Jason Railton
* 8878 Rechargeable battery
* XL-motor for lifting boom
*
PF-lights
* Improved bucket looks and operation
* Improved dipper range
* All the gear-reduction
moved to the undercarriage to reduce mentioned side-effects
* Cabin roof
Altogether
these mods considerably enhance the playability of the model.
The remote controller
deserves some extra attention. It's an adapted version of Jason Railton's Thumbstick,
which I found on TechnicBricks Blogspot.
Because it works so well now, I decided to make photo-instructions for this mod so
everyone can turn their 8043 into a real mean digging machine. The instructions can
be found in the download-area.
