Would a 1999 RV6A kit have the 'newer/approved' nose gear? What exactly is the difference in the 'new' vs. 'old'. Looking at purchasing partially completed kit and deciding on whether to finish it as an 'A' (as originally purchased) or to convert to tailwheel. I do a fair amount of grass strip flying. If the kit has the 'older' 'unapproved' nose gear, what would the cost/problem be to upgrade it. Thanks in advance from a future RV'er.
