Been using this KO PROPO EX-1 MARS for sometime but bought the KO PROPO EX-1 UR 2.4GHz few months ago. I tried other controllers but didn’t like it that much. Maybe I’m so used with the MARS design such as the bulky squarish shape, weight, responsiveness, trigger position, trigger travel, steering position, steering resistance, grip size, options/features, menus, etc. So then I decided to upgrade the MARS to UR. Used it during Yokomo GP 2008 Round 1and simply enjoy it. It has the UR features (Ultra Response) whereby I managed to set the steering response to ultra-ultra fast. And much lighter compared to MARS. Menus are easier to maneuver then the MARS. Life a lot easier with the 2.4GHz module, no more frequency clash. And not to forget that the receiver is so undescribally small, you got to see it yourself.

Most may not like it but don’t ask me why but its too personal I love the KO PROPO EX-1 series.
