How big is my KOMATSU PC650?

Some people asked me how big is my Excavator?, not sure actually, 
but I'd checked the website and make some comparison on my own below:
Below is the 1:10 scale dimensions for my beast..

The final piece - main cabin cover

And now, the final piece of this custom build excavator...the main cabin cover..the gadgets inside are sitting at the actual final location, we gotta squeeze the space as much as possible here due to real big stuff at the back there, no more space available...sorry pilot...your place has been taken.!

 CAD image...

 and the real ones... 

Side view, CAD image
 ..and the actual... 
...front view, CAD image...
 and the actual one...cant wait to install them on the demo unit...soon..
pls note, we had to use driver cab for the electronic circuits/ESC/2nd battery, as we are running out of space here, this 2nd battery will supply 12VDC to undercarriage motors, as well as servos,
it's smaller in size due tolow in consumption, i hope. The 1st or main battery at back cabin will 
just supply 12VDC to hyd pump, and it's the bigger in size for longer run time.
more details DECAL for main cabin will come soon..as to copy exact the real ones...

First ever full HYDRAULIC test!!

And now, moment of truth...all system in place, time for full hyd test...see video below. So satisfying as all functions are running per expectation, the hyd movement should be smoother as we exercising this unit more often, as the o-rings and seals are yet to be fully intact/seasoned. Main cabin cover is now under final touch up on powder coating while second excavator unit is going to be ready fast..
Pls note, the digging park is just a small end corner of a flatbed lorry, not much space here...still it runs ok..
our true digging/garden/RC sit/area is yet to be ready..soon..need more sand here.!!
 Looks shakky a bit due to poor terrain condition/stiff slop and cabin counter-balance weight is 
yet to install at the back of the main cabin...should be dead stable...this 50kg monster.!
