That's great crane Alvin, and looks even better with the jib. Well done!

Dunno about Alvins, but my CC-2800 only needs the extra ballast while raising
the boom. Once it's up, the extra ballast can be disconnected, and just rely on
the counterweight attached to the superstructure. Of course I have to be careful
not to lower the boom too far without the extra ballast.
