Well, I have run out of things I need to do to my Slash 4x4 Ultimate, and am now looking into wants. I really only bash, but I appreciate good handling. So far this is what I've done/have:
All stock electronics (working fine)
2.8 Trenchers on desparados
Blue springs front
Green in rear
60 wt oil front, 70 rear
Diff fluid: 50k front and rear
Revo axles all around (modified)
Digital LVC led display(LVD disabled on ESC)
Rapter SCT body (shoo good and taped)
RPM bumpers, nerf bars, a-arms, wheelie wheels
I think the next step maybe a new servo or motor/esc combo.
Only problem is; they are working fine!
