Just a note to everyone that the 2018 Rule Book clearly specifies you must use the older (red) TranX260 Car/Bike transponder. This should also include the X2 Car/Bike transponder. Don't know if the Rule Book will be updated or if we'll just use a Supplementary Regulation to include the X2 transponder until the Rule Book is updated for 2019. With the old timing system there was no real issue with using, maybe, a kart transponder (i.e. a yellow TranX160) or (*gasp*) an RC transponder. That has all changed with our new X2 timing system. It has introduced what they call Sport Segmentation. This means if a transponder is detected that is NOT specifically for our sport (Car/Bike), that transponder will be identified as Incompatible and WILL NOT BE SCORED. There is no way for me to override this. On a positive note there's some features in the new system that are going to be reviewed and could have an impact on how our timing and scoring is presented.
