I drive a losi and use Hudy. I have not had problems getting my truggy dialed in on a hudy. Just for FYI a Hudy on any car won't make you faster. What it will do for you however. Is assure your care is set up right and allow you to concentrate on driving and correcting YOUR mistakes. I did become faster after using the Hudy station however it was for the above reasons. Not because a Hudy is some magical cure all tool. If you have the money to invest in one do it if not don't sweat it.
