The free downloaded has limitations...but its a good start to see if its worth the money to you.

yeah i all ready got the trial one. just wondering how much better it will be with the controller. and how realistic it might be. to get me better in actual r/c racing

The game design is a little amature imo. It is very good as far as R/C games go but its noway worth the money they want for it.

Good bits
-Semi realistic
-rostrum view is nicely done
-low system requirements
-good vaiety of cars and tracks in the full version

Bad bits
-some dodgy programming
-some weirdass physics (car slides the entire length of the track on its roof at 20kph)
-whiney sound effects
-zero damage
-tyres start to wear out after 3-4 laps
-cost
