I guess my explanations make no sense to those who have not built/ experimented with models at the extremly low weight / slow speed end of the spectrum .
I do understand that .
My reason for the seemingly absurd comments about weight and balance -are simply to give some other lines of thought -
I am oft times put off by answers given to novice modelers -when they ask about why their model snaps out on application of elev - etc.
I see formulas and answers which may be of importance on some full scale stuff - but on these small models - the real reason is simple and direct - the durn thing is too heavy -.
One can speculate on airfoils/ cg's etc.. which are less critical etc--but on the models - the real culprit is --99.99% of the time - simply weight .
if the weight is low enough - the cg importance is greatly diminished.
Your disdain for formulas and the "old theories" has been well documented in several other threads. It is not the topic here. In what sense is the importance of CG diminished when the weight is low enough? Are you claiming that the well established requirements for stability do not apply below a certain wing loading? Can you explain this in any way?
Your absurd comments are a poor way to "give some other lines of thought". As an alternative, you might consider simply articulating some "other lines of thought" directly, as the absurd comments are simply inaccurate, not thought provoking. No one was throwing unnecessary formulas around, or citing any obscure theories in this thread. You volunteered your homespun anti-old-theory right out of the blue, and it is unmitigated nonsense. If you can justify it as anything else, I'd love to hear it.
