try to check if the gyro is touching the wheel shell..... if that is the case use some spacer to center the gyro. I am not sure if you can install the mm450 electric gyro in the vmx. Which works a lot better than the stock mechnical one.
bike with gyro you need to be really hard with the brake. As the gyro with try to make the bike keep going forward. with my arx540 I need to lock the rear wheel and slide the rear end to make it turn. which is kind of cool. I sold mine already. I got a arx540 nitro but don't have time to build it yet...............................
