Friends..is there anyone to share some ideas and pics about excavators...?

all my models are paper and working...

backhoe...

here is the video...

Wow excellent work! I am quite speechless!

Wow that's awesome!
I've only built excavators out of Lego Technic and Power Functions

This is very interesting...    I've always thought of building something like the Rover (used in Mission Mars).
Linear Actuators work great and are a substitute to hydraulic/pneumatic actuators.
I'll think about building something like this (after my X std boards)  - 


In the picture above, standard servos and acrylic glass is used.
Imagine using High Voltage Servos and Carbon Fiber !!! 
and maybe using an Android Phone + Java app to control it.
That will take a lot of time, effort (and money  )

sir..its far beyond imagination...and inspiring..its a nice machine...i hope we will get ample of ideas from here from now...thanks for the confiuration..but i have some limitations here, as i do not have a professional radio with me..all my efforts are based on self made radio,mostly on FM and SW..i hope i will buy a good radio set, by saving some money from my modeling works..from your picture i can see its too easy to make a craft by using professional servos..now i am working for the Naval academy, to make a big UAV, with all features..so all possible ideas are welcome, for a great realization of my craft...thank you all...for the great inspiration...have a nice time...

here is some interesting Rc Hydraulic Excavators videos..
