Some comments.

This model was great fun to built. I am sure I will make another attempt to built a bigger one, with more
axles. Because I didn't have more engines, I couldn't make more things motordriven. The model had a few
weak points. The frontaxle was not strong enough to hold te crane while turning, sometimes a wheel came of.
The design of te upperstructure was not very nice, the cab is way to high.
