Re: Cat 777D Mining Truck
3 3/8's = 85mm, tam trk tires are 83mm.
To propel the haul trk and to save on space you could use gearhead motors directly on the wheels, just like my Stahl Volvo adt. That truck has plenty of power & good speed too... though I don't know exactly the rpm.

Re: Cat 777D Mining Truck
Looks like a good start for the build. Gearhead motors would save lots of space. If you need any ideas for what to use for the electronics, you might want to get with rc farm guy. Not sure if this is his name on this forum but he has r/c'ed lots of diecast vehicles. He has helped lots of people with their vehicles.
