Hi hobbybobby,
Most of what you say in your rant is correct or at least in part correct. I have been involved in building and flying model aircraft for over fifty years and derive great enjoyment from problem solving whilst buildingwhich usually culminates in a model that gives great enjoyment when it takes to the air for the first time. If you are unable to problem solve, improvise and adapt and enjoy these processes I don't think this is the hobby for you as your frustration will overpower any enjoyment you may derive from this pursuit. It's supposed to be fun

.
Cheers,
Colin
