revopqrs that welcome to the hobby was directed at wriff wraff not you yes we are coming out with new shorter arms they are running stock though so basiclly they could change at any time they are not a new part number or anything like that im sorry you took that welcome thing the wrong way but it was not directed at you. we are reconsidering redoing the truggy kit to include tires and a body and stuff as well and as far as your air filter the one that comes in the pro kit comes off the carb and goes to the right so it sits right above the chassis brace and is on one side of the motor just like the rest of the truggy filters out there .
