Congruaualtion on the purchase. I have a Matrix myself. It is defintely the best RTR buggy in the market. I am kicking butt with it every weekend. YOu made the right decision.

If the remote stop working and car run off, you might wanna give airtronics a call about their MX3 radio. Mine works perfectly. Regardless, it is pretty common that servo / motor will be fried after a run off. Try to contact CEN too, they have very good service. I call Andy almost every other day and ask for his race setup.

also, definitely use a receiver pack instad of AA. AA wont last long with the stock servos. I remember i was like that when i first started years ago and we dont have such communicatin channel like now and it was a lot harder but i made it so can you.
