Hey guys, I got a chance to try the new LRP SPX this past weekend. I was on a fairly big track at 60x100 with a sweep on and off. I ran the Tri Duo at 10* time with the Sphere Comp rolled at 75mm which was plenty fast. I dropped the SPX in, geared down to a 67mm r/o, timed the motor at 0* & punch mode #7 as per some prior recommendations. It sounded like it was going to blow the foam off the wheels! But on the track, it did not impress me at all. I geared down two more teeth and it was about the same speed. I changed it over to mode #5 & #6 which seemed to take that radical active timing away from the profile. With the motor timed back up to 10*, r/o at 75mm in mode #5, it was basically the same as Comp. I totally struck out with the active timing profile. Anyone have a better recipe for 4 cell 13.5?

The guys said they sold like a million and half of these things at Birds, so someone had them figured out!
