While I agree it is an easy way to get into the hobby, I feel it does more harm than good in the long run.
I won't address the fact that it doesn't teach any building skills for future kits.
I feel it doesn't teach engine tuning and a lot of the setup tips that may haunt the individual in the future. Lack of knowledge of engine tuning/simple mechanical/aerodyamic and electrical principles, in my opinion, appears to be a growing problem in this hobby.
I have always felt if you build something to make it idiot proof, they will build a better idiot.
