RE: How to handle the guys with flawed plans?
The biggest plus (IMHO) with club flying / training is that you can learn from others (good, bad or ugly) experiences. If that saves a plane or two - good. If that saves your finger - great. If that saves someone else's finger (especially a small fry) - fantastic.
A couple of observations (not mine - just sharing):
On RC flying - in your 2nd year you are likely to crash everything you bring to the field.
On driving a class A vehicle - the most dangerous drivers are those in their 2nd year 'cause they think they have learned everything there is to know about driving.
On driving a race car - you exceed your limitations and it's gonna leave a mark - maybe just $$ but could be a lot more personal.
Good flying ...
BTWchuck - I used to teach the DBA, admin, technical classes that you figured that you didn't need. My customers wanted to insure success and avoid failure because the success of their companies depended on it. Risk, reward.
