Cen matrix is a great RTR and comes with a great radio for the price, I have raced this car and I will say that it handles well out of the box. the engine isn't the best on the market but that is how the manufacturers are keeping RTR costs down, by using less expensive engines in the cars.

also the sportwerks turmoil rtr comes with a great radio and the mayhem is a great car that doesn't get the credit it deserves
