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:
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.
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
these mods considerably enhance the playability of the model.
