Cen Matrix TR Arena FRE - Brushless

5s on MM controller
realy good conversion, as other guys said, very clean. I like the platforme of this CEN truggy. And for the cross pin mod in the diff, it's very good, because with stock diff, they don't hold very long with nitro engine.
But i think the new version of the Matrix (buggy and truggy) have the new crosspin diff as stock unit.

But you are sure for 5s on MM controller
