Thanks.... I would hit up Paul Sims a BEZERK RC on facebook and he can get you all set up with the chassis.... I am going to have a few extra sets of diff cases modified up so that they will work in the 502x gearboxes ... So you can PM me if you would like a set in a week or two

And you are welcome as well.... I liked my TRF502x.... But it needed somebody to give it another chance...

and that's where the TRF502xs design came in
