RE: what's wrong with these people
Isn't this the golden rule of R/C?
If you're not having fun, you're doing something wrong.
If someone else you know is also into R/C, bring them up. Help them have fun. If they're buying something that's low-quality or not really good for their application, be a friend and constructively point them in the right direction.
This is our hobby, right? And the goal of a hobby, at least in my eyes, is to help me enjoy my (very little) free time. So enjoy it!
