Its more the point of how the parabolics will work compared to my coils. Also its an exarmy chassis thats too good to destroy. You dont have to run the front shaft out of phase as the front diff pinion angle is std rangie 6deg. If it was inclined more than that yes you will have to but not as much as 45deg, more like one spline on the slip joint. I dont have the formula handy.
