I apologize for not being more pointed a couple of pages back.
I think it's common wisdom that the Losi rewards its driver for agressiveness, and the AE truck requires a smoother, more conservative approach. That translates into the AE guys are going to be driving it in a little easier, and the Losi guys will be DRIVIN' IT IN 'DERE. To me, the easiest and best solution is to get the AE truck faster so you can gap the Losi guy in the section right before the corner so the other guy
can't get to you.
Certain users here have reported good luck adding ballast. Certainly nothing wrong with doing that, but IMO not my favorite one. AE went to a bunch of work to make the truck lightweight, so to fix the truck we're going to add 10 ounces of ballast?

Problem with that slippery slope is you wind up needing the 550 motors the Losi guys all seem to run. And then your truck stops being fast in all the spots it was faster than the Losi.
But that's not going to address what other users have reported about being slow in the sweeper and getting nerfed. That user needs to work on setup so the truck can run competitive speed in the fastest part of the track, because outside of that, nothing is going to stop you from being the football in a game of punt nobody wants to play. Without driving your truck or seeing its setup in person, I'd be inclined to say you should stiffen the swaybars or make a ballstud change, but you'll have to do some testing to figure it out. Ultimately, the solution is to get you faster in the sweeper, not to stock up on chrome horns.
I have to wonder how many users who report getting manhandled by the Losi trucks are running the stock slipper.
