1/16 Oliver Dozer Conversion

I think it is going to work. I have one real loose and one tight side and at this point no good way to control tension. This particular die cast uses springs on the front rollers for tension but the travel is short and not designed for this sort of use. I haven't figured out just how yet, but I plan to make the rear motor pod adjustable in some sort of sliding action.

The blade lift servo seems to do okay, more testing required. Really frustrates me that the specs of the sabertooth controller and spec of a hitec 645MG indicate that it should work fine, but obviously that ain't true! FYI, even when I ran a separate bec for the RX from the same power source it acted the same way. So, that makes me think the sabertooth is putting out some funky RF causing the RX to act up. All this behavior is while the servo is sitting idle, so it must really be drawing some power even idle?

I should have also mentioned that if the RX is powered by a different battery completely isolating the RX, AND servo from the motor controller that then it all works. This is exactly how I ended up doing it in my crane. Don't have room for a second battery in the dozer.

Anyhow, enough bitching, here is the bench test video!

Here is a short video of the first test run in the dirt. I am out of practice and i have to solve the loose track issue. Otherwise I think it is going to be usable.

It looks good in the dirt, seems to have plenty of push. I have no experience with those motor controllers but have a couple trucks with 645 servos and they are serious power hogs. I run a receiver battery in the trucks that have them so I don't notice it.

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!
