I have an HPI RS4 3 EVO and I just cant get the damn steering to go straight. once i get the steering trim as close to straight as i can get it(still not that straight) the next time i trun it off and back on i have to re-trim it. It is really annoying because at my local track the straght is on the opposite side and even in the tower it is hard to tell how clodse to the wall you are and i keep drifting over to a wall due to the steering!!!!!

I could really use some help

Thanks
