A French AFOL have just shown at SeTechnic forum, a new image from the new 8043 (Excavator) with much better definition.
It was taken from the 2010 Trade Catalog inner pages, in opposition to the former image taken from the end summary.
This is indeed a much clearer image, which allows to eliminate some doubts. But not that much...
- The IR remotes are indeed the same as those already used before.
- In my analysis the existence of three LBG Axle 3 sticks and one extra stick in red, is a good hint to support the 1+2x3 operation theory.
To me the red stick looks perfect to command one motor that simultaneously switches a set of Driving Rings and thus changing between two sets of 3 functions at once (boom, dipper and bucket, or drivetrain and superstructure rotation).
Also it seems to be written somewhere "remote controlled driving sharing and turning". Don't know exactly what does it means but it seems to support the same theory.
- From the gears seen in the drivetrain, it is clear the tracks are motorized but still not clear if the remote makes the drive train to skid, for those still septic about this function.
- Drivetrain uses some studed Technic parts which are always welcome these days. Also the sprocket large wheels seem now to be released in a new color (DBG or Black, despite I'm most in favor of the first option).
- The superstructure and arm fairing uses a lot from the new panels in yellow, which is also a good source for the panels never released before in this color. These produce also some nice looking curves to this model main body.
- At the rear-up, left side of the superstructure, we can easily distinguish the top from two PF IR-Receives as suggested before.
It is for the arm details, that things are not yet so clear...
- We can't easily distinguish any axle routing to the Linear Actuator responsible for the bucket movement, which makes some still suggesting a combined dipper/bucket control.
Personally I don't believe it to be the case, as it would be too much disappointing for such a flagship model.
- The guy who provided the pictures, also tried to reproduce the Excavator arm from the new image, and came with one interesting question. See his reproduction from the pictures below.
Either this is an incomplete and not a functional model, still to be changed, and the double Linear Actuators in the boom with a parallel synchronous setup simply can't work, or his interpretation from the image is not enough accurate which is to me the likely case.
You may recall some possibilities for such parallel synchronous setup, from section 5.3 at the former Linear Actuators review (Part II) here at TBs , made from the Technic parts available at the time.
One possible solution to the mystery, could be the usage of new 20t bevel gears with clutch (87407)!?
Thanks Anio, for letting me know about the news!
