i havent seen them. yet.... but if they are true 1/64 or HO scale then they would be very simmilar to hot wheels. hot wheels are pretty close to scale. however the wheels on hot wheels are a bit funky... best way for us to find the exact scale is for someone to auctually measure the body of the car. and then find the measurments of the real car that it is a mini version of. unfortnately they wont be exact to scale. they suffer the same problem that bits and all other rc cars have.. a fixed wheelbase.. because the wheel base is not the same for every car. you have to scale the bodys to fit the chassis.. which causes some bodys to be 1/64 and others may be 1/60 or 1/70.... depending on the car..
