I just got a losi aftershock and was wondering what do you recommend as upgrades needed for the truck? Busted my engine and am going to put a new LRP 28 spec 3 engine and what will i need to handle the power? With the RPM arms do i need to convert it to lst2 specs? Whats a good pipe/header combo for it too to add extra power to the truck. Any ugrading i need to do right off the bat? Anything you know i would like to know. thanks a lot.
