i think we can live with both types of building .i love to scratch build but find my self getting a bit to emotinally involved to have fun flying it. thats were the arf comes in for me.dont get me wrong i love to build and fly my scratch stuff.but i feel a littel easier taking chances with a arf.i think unfortunally the kits days are numbered.they were a great steeping stone for me.but you cant git rid of scratch building its been around longer than hobby stores.
