I forgot what diffs are... I was soo into RC Trucks until I found out about RC JEts that I got carried away...

diffs are differentals... they allow one wheel to turn at a different rate than the other.

ie the powered wheels can turn at different speeds, ie have different amounts of power going to each wheel without having to waste power. different wheel speeds are especially wanted when turning

Ok so now I hear that Ofna's Dominator has weak diffs? Can I replace them?

most probably they have diff upgrade parts. like diff gears made of stronger metal than the stock ones. but i no nothing about onfas optional parts,brobly try their website

The only stupid question is the one that isnt asked.

There are no stupid question.. just stupid answers
