Hi Zabco
the total length will be about 850 mm and the blade is 460mm wide (think its a coal blade). depending on a test on how it pushes dirt I may have to opt for a smaller blade width. ill see how it goes as with most of this, its trial and lots of errors
I threw all the metal for the blade and ripper on scale with the chassis and its already at 55kg ! its hard enough moving it about already !
can recommend the Arduino enough but If you use the code you will have to tweak the input ranges for your specific RC transmitter/ deadbands. I am sure they all vary a little bit.
