Hey Joey4875 I had the same setup I think the ideal FDR for the 100 foot is about 4.8 - 5.0.... I would recommend 4.9 to start with the SPX... I did not experiment with lower physical motor timing like Adam suggested I had it on max while using SPX.... which may be the reason why I had to use negative exponential (dx7) on throttle to get the spx turbo/timing advance to kick in early...
i'll be testing tomorrow late afternoon with a few other folks if you are planning on coming would be great
