On grass, all 1/10 struggle. Honestly. So don't even use that as a basis of comparison.
Also, I call shenanigans on running a 2WD Slash (or any 2WD 1/10) in 5 inch mud. Seriously? 5 inches? Take a ruler, measure 5 inches tall - that's high. Compare it to how high your RC sits.
Make it sludgy mud (not dry dirt - but MUD). Try to run though it. You won't easily. Your rear diffs will spin out as one wheel gets stuck, and your shoes will get caked fishing it out.
C'mon guys - it's good to be proud of your RCs, but be realistic.
