Newb - Trying to build my first excavator

[michael]

I am new to RC in general. I have been doing a lot of reading on here to try to figure out how everything works. I want to have hydros that have good digging power. I have seen in another tread how to make the tracks. I am going to have an instructor at a Tech College help me with the metal work. I need help with the hydros and the electronics. Can someone give me a list of what I need? I also am having troubles trying to figure out how to make tracks turn 360 without twisting the cables. I would just buy a completed model and then take it apart to figure out how everything works, but I don't have that kind of money. Also would it be possible to do this with a $1,200 budget?

Thanks for all your help!
