This is going to be a touchy subject,and I am not out to insult or discourage anyone...
I have spent many hours reading endless posts on this website and I really like RCU.
I am a little concerned about Arf's and how easy it is for anybody to have a RC aircraft ready for maiden.Not too long ago we all built our own aircraft and it would take some intelligence and drive to archieve and actually get an airworthy airplane.Instructions were fairly thorough and many details were adressed.(depending on kit)We learned through this long process to respect the planes, and as we built more we could determine faults in kit design and intructions.Through experience many of us have become responsible builders and excellent pilots.
It seems these days many companies are offering good looking ARf's that are affordable and many newcomers can easily be ready for flight in several days.In most cases the instructions are broad and poor and some manufactures are selling a some what unsafe product.This is just my opinion of course,but I really do believe that everybody should built a kit in their early stages and get to know what thrustlines,incidence/firewall/engine offset/fin offset/ are,how to cover an aircraft..etc..
