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.
