Motors and speed control arrived and are installed.
Seems to function well and have good power. I think I should have opted for a the higher amp sabertooth as the 2x12 goes into protection mode long before the 17rpm motors slow down let alone stall out but I think it will work for now. I have to make all of the small idlers for the tracks yet so when I get those done and the tracks stay on
I'll post some video of it in action.
Thanks for the complements!
