十年前左右 that one is call Ricky. The first motorcycle have electric gyro is AR racing from Italy. Now Kyosho mini bike, the toy scooter(can remember the make....), MM450 all have electric gyro. AR racing help kyosho to develop the system for their mini bike. And the skyrc is a direct copy of the AR kit. But parts are not interchangable.
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...............................
