9396 - Helicopter
Guess we have already dug enough on this one before...
However realize it becomes clear from the arrows in the box, that we're going to get pitch control on the main rotor blades.
Just noticed also the photos show the old style for the 'Technic Liftarm Triangle Thin', instead of the new one.
Were these finished images that old, considering the new type was already available with the 1H sets.
9398 - 4x4 Crawler
We come to see finally which are the official names for the new PF motors and where each one comes, without margin for doubt.
So we have:
- PF-Servo Motor: There is one of it in the Crawler and it might be the one in the center of the model. So we get one for steering both front and rear axis.
According to previous descriptions from those who have seen it, it should allow an axle to pass through, or at least allow to connect two axles - one in the front and another from the back!?
Honestly I prefer to wait and see it, before entering into more considerations, because the image still suggests several possibilities.
Looking at the connection head, it looks to have a 3x5 oblong shape with multiple connections, also in orthogonal axis. It makes me also think it might be a strong servo.
It remains to know whether it is a Full CW / Full CCW, or it supports PWM control for intermediate positions. And whether it implements return to center, or not?
Nevertheless with the IR remote used in this model, here it might behave like full CW / CCW mode.
- PF-L Motor: Well, finally the missing 'L' in the PF motors range.
These might go to the front and rear axis, to drive the Crawler and do all the heavy work!
Guess they will run at moderate speed, but with high torque. Although I don't see a significant internal planetary reduction gearing fitting inside this...
The several pin connections available, from orthogonal axis (very welcomed) also suggest a strong motor that needs steady fixation anchors.
Just looking to put my hands on, to dissipate all doubts I still have about these...
It is also good to see the 36T Double Bevel, returning into a couple of new Technic sets.
