You got me googling for some more info about that wide cure and among others the link to your topic popped up.
Can you post some info on the Carrera adapters?....you definitely got my attention.People are complaining that there's no 100mm spacing but you have carrera track for that. There's also an adapter for Carrera coming out (or so I've read) so if you want the tighter radius turn you still have that option.
Glad to contribute Merc.Thank you slotcrazy! Very informative and way more effective than my fiddling.
