I haven't been on in a while and I got a few PM asking if my 5.2 was all sorted out.
It's dialed! I ran last Wednesday and finished 2nd 13.5 Blinky behind a guy running 13.5 boosted (he didn't have his lap top there to change the mode). I am running Keven Hebert's setup. My only change was going to silver side springs to get a bit more steering and running Mag F and Pink R tires. I am going to try Mag R next.
