good day!
i am new to r.c and aero dynamics and was wanting to build some simple flat plane flying wings out of fanfold or depron.
is there a basic equation to determine c.g. of a flying wing?i heard that 15%of m.a.c. is a good start but i dont know what that is and if it would be the same for planes of different shapes, sizes, etc.
i built one based on tom hunts elipstik and it flew great on prescribed cg but other models did not fly when i applied the same c.g locations.( did not seem to be any where near 15% mac on the elipstik model...but i dont know how to calculate..)
help stop my confusion... i am running out of foam!!!
my power system is a gws 350 d geared and a 7cell 600 mah pack with a 10x4.7 electric prop.
