It keeps getting better...
Today I put bearings in the main drive assembly. I'm sure that will help runtime and power to the dirt. Added a dual rate and slowed it down to about half speed so I can control it pretty well when pushing. This way I can hold the stick full forward and steer, while running the blade with the other stick.
I think I might have a bit of descent footage finally!
