Overview

Entirely built from standard parts (motor, R/C control, load and counterweight excepted), the models weights about 32 Kg. The boom is 2.10 m (6' 10") long, or 161 holes (SML 4 is 123 holes long, and the manual cover "long-boom" version is 135), which allow for a total trolley course of 1.12 m (44").

I didn't try to model a real prototype (see References), but kept the manual covers model main proportions, including the too much high base, mainly to stick with the Meccano traditional icon.
