Maybe why there could be a big decline in ARFs as well.
I'm in the process of building an ARF, trust me, my patience and problem solving skills have been tasked well beyond my means with poor instructions and really bad parts and assembly. And of coarse, I can't get replacements because everything is out of stock. I'm back to building kits and scratch building after this project. At least with a kit or a scratch build project, I can create and solve my own problems instead of trying to comprehend problems caused by someone else.
