I'm trying to set them up now; quite fiddly at times
, but they look sooo nice.
The forest house set has 2 rope ladders; the leafs and branches of the trees have small pins to hold the birds/squirrels. The house is indeed system-x; The ground plate has the possibility of extension (there are connector holes at the rear edge). The house has a partial living quarters (reminiscent of a summer cottage). In spite of some people finding it a bit disappointing as for possibilities, I think it is quite lovely.
The jeep is really neat with swinging rigid front axle and small trailer with fully articulated connection between the jeep and trailer.
The tractor has a moveable hood; the logging trailer has a steerable front axle with fully articulated triangle connection to the tractor. The logs consist of 15 segments (each has 2 parts) that can be connected together indefinitely. The set standard is 5 logs. The trailer has 2 metal chains and an elastic rope to secure the logs (the chains are on hooks that can slide up and down vertically along four guide rails. The trailer has rubberlike tires.
The oak tree has three shades of foliage and a leafless branch as well.
So much for the preliminary description; I'll try to make some pictures tomorrow.
