Since yesterday new other pictures from the 2H2012 LEGO Technic sets were brought to surface by Cypr-21 at EB.
These included images for the respective B-models, which in a couple of cases were still unknown, and one or another further detail. Click on each image to see it in full resolution.
Let's look on each reference then.
9393 - Tractor / Buggy
Except for a new image from the rear view, nothing else to add about the main model.
9396 - Helicopter / Intermeshing Rotors Helicopter
Here the introduction of the model rear view (in the middle) where we can see also a PF M-motor attached to the main rotor in order to make it spin, and the hatch in its lowered position.
Recently we got to see from the box details and the arrows in it, that we're going to get pitch control on the main rotor blades.
intermeshing rotors is definitely something new in the LEGO Technic products range.
Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions, with each rotor mast mounted on the helicopter with a slight angle to the other, in a transversely symmetrical manner, so that the blades intermesh without colliding. The arrangement allows the helicopter to function without the need for a tail rotor besides we got one in this particular model, also at an unconventional orientation. This configuration is sometimes also referred to as a synchropter.
It might be definitely interesting to play with.
9398 - 4x4 Crawler / Truck
No big news here anymore, but quite interesting the way the main model body opens up. It seems quite easy to customize and replace by your own version.
From the full side view, we are still not able to figure out further details on the Servo Motor and how the shafts connect to/through it.
The chassis looked the same, as someone pointed here in the comments.
And now... did you choose already which model are you going to buy for your Christmas?
