Help Crane builders
Hi,
I wonder if any one can help me?. I am building a Leibherr LTM 1030 2.1 crane, and cant figure out how to get the boom to extend. I understand the full size principal, but cant see how to get a 1/14 scale boom to extend.
Most articles I have found seem to miss out the extending boom ,other than to show it working
