Just enjoy rc flying.yes arfs are assembled and kits are built.and if your one of the very few able to build from a set of plans great.but when its time to fly who really cares just fly and have fun.i am finishing up a sig liberty sport .a friend was going to finish building but lost interest .I have had so much fun with it that I decided I will build another one.i was trying my hand at 3d flying and while I learned alot I was ready for a change.i have flown numerous arfs.i have a wildhare 260 with a dle30 fantastic plan.i have a dynaflite pt 19 .balsa built. And several 3dhobby planes.my last biggie was a a giant stinger with a 3w60.my point is who cares if someone assembled it or built it.i respect builders as I do it on infrequent occasions.but I I used to have a hurried carreer and building wasnt always an option.stop knocking anyone who assembles .be happy to fly and ppreciate the merits of this great hobby.
