Very early into my time in this hobby (about 2 years ago I think) my first build was a chuck glider to RC plane hack.
My biggest problem was figuring what everybody kept calling "cg". It didn't make much sense to me, I didn't have the knowledge or terminology then (probably still dont).
Some thing I have learned,
"A nose heavy plane flys poorly, a tail heavy plane flies poorly once"
-J. Bixler
I knew I wanted the plane to nose down. With enough nose weight the fulcrum could be under the tail. What I have since learned is, what I meant to be asking was, "where is the balance point?" from there you can
*effect the center of gravity of a plane by loading and weight distribution.
*effect the center of gravity. that's to say the "cg" is moveable the balance point is fixed.
So the whole point of this post is to hopefully change the lexicon or mindset of the hobby a little bit..
don't be so quick to say the words center of gravity.
So you put a new bird together, the first thing you do is 'check cg' by balancing your plane on your finger tips. On The dots/bumps/divots on the wings or balance point.
Cool if its a arf, bnf or speed build kit, those planes have the balance point marked, but if its a scratch build like my glider was, you have to know where the "balance point" is not the "cg" is because the "cg" is relative to the balance
point. <---- THATS IT !¡!
THATS IT ¡!¡
Thats what I am talking about. When a model is checked for cg, the The dots/bumps/divots on the wings are not actually the "cg" but the balance point.
I wish especially in FT videos the "balance point" was mentioned just before the "cg" and it was stressed "these are the balance points."
Some helpful videos / formulas could be, How to find the balance point of an airframe.
Very tired there's probably. Tons of grammar errors. Sorry, good night.
