Impressive! Never seen such a crane before built of LEGOs.

Sounds interesting!

> · Scale (Model/Real): 1:30 (approximate)

> · Controls: 4-channel R/C from Hi Technic

> · Counterweight: water (in plastic bags) and battery
> · Total Height: 6.5 feet; 2.0 meters
> · Boom Length: 5.5 feet; 1.7 meters
> · Total Motors: 14
> · Thrust Roller Bearing: 29 Wheel Hubs (30.4 x 14 VR)

Only 71 hours, that's not much for such a high tech crane. I wish I could
see the crane in real once. It would be great if you can show on the
Modelshow Europe ;-)
The visitors like the LEGO models! Especially when it's a real working model.

9.5 pounds = ... kgs??? Sounds heavy, so the crane has a great lifting
capacity. Is the boom strongs enough??? You have to take care of sufficient
counterweights or else the crane will collapse.
Nice job!
