RC4WD Dozer, modifications, upgrades, settings.

[Mavv]

I just got my dozer a few weeks ago. First thing I did was swap out the two speed controllers for a Sabertooth one so I could control it with one control.

I now have the movement to my left sticks, and my right sticks control the blade which makes it much better to control.

Decals are ordered and lighting, but other than that I haven't done anything else with it. Do those tracks really need to be lock tighted?
