As a HUGE newbie to HPR what is the difference between these two organizations? I have an NAR club close to me and a Tripoli club about 3 hours from me. What are the differences. If I want to be apart of both can one do that? Any information will be greatly appreciated! I know Tripoli will allow sugar type engines which is something I am interested in, but as of right now just getting into the hobby what should I do?
