[TC25] 42009 1:2 scale

[Pas_de_nice]

Hi all, I will try to find the time to finish my entry. I have made several attempts in the past, but never made it to the finish line in time.

This time I post something in order to feel bad if I am not able to show progress

I try to implement all the functions:

-steering with different angle for 4 of 5 axles

-outriggers

-superstructure rotation

-boom rise

-3 stages boom extension

-winch

-fake engine connected with differential

 

I have made some progress in LDD in order to be confident that all function can be implemented at this scale.
Here is wip picture next to the full scale 42009 :

I like that you're going outside->in and not inside->out as everyone else. That may be interesting to see the problems with steering vs drive shaft and how will your initial external design survive the clash :)

[Pas_de_nice]

Actually, it is partially inside->outside too since the steering is implemented already, so as the dirveshaft for the fake engine. Now the challenge will be to route the outriggers in such a confined space but I am fairly confident
Here is a view from the other side :

Nice work! That multi-stage boom looks quite ambitious at this scale! The model overall reminds me quite a bit of the entry I'm working on, since both sets are a similar size, with somewhat similar functions, being scaled down to the same scale.

I would be worried if those two small linear actuator can pull this multi-stage boom up, it's too much load on them/for their safety mechanism, I think. I tried using one of those in a simplistic boom that is pretty lightweight and one of them wasn't enough.

Ambitious project, and good work so far. The two stage boom will be cool to see when done.
