Try playing with the dual rate. My home track has a bunch of high speed sweepers and only one pivot turn. I found that by turning the dual rate down to like 80 the car came alive. I could still get through the 180 by breaking hard at turn in, and everywhere else the car was super easy to drive.

80 might not be the number for you, but my guess is right now you have too much steering.

Can someone be really awesome and post some pictures of their modded side pods for running the battery sideways?

Or, if someone has already posted pics, what page(s) are they on? I don't quite have the time to pour through 700+ pages so I really appreciate it.

Diagrams are cool too, I just need to know where to cut, how far, how deep, etc.

Thanks.

Any rumors on an upgrades version of this car? Like a FT kind of thing. A team driver mentioned it to me before the holidays, but i have heard nothing anywhere else.

Sorry if they are old and dirty, from last season when i did it. But you get the idea lol

These are longer so i can also use saddles sideways or slide the shorty forward or back. If you dont want to use saddles or be able to move the shorty then dont go as long obviously.
