Hi,
I just ordered a E4FS and I will like to know what roll-out do you suggest for a Ballistic 17.5T ?
The track is 75’ X 34’
I also see that the E4FS has a FDR 1.888 and the E4RS has 2.059 ! I like to know why there is 2 different FDR because apart from the foam spec and the rubber spec they should be same tranny…
