There is plenty of info online regarding building & design of RC aircraft;
this link is particularly useful:
http://adamone.rchomepage.com/cg_calc.htm
for calculating the numbers for your plane to make it fly correctly -
Centre of Gravity, Neutral Point, Aerodynamic Centre & such things.
I found it usefull for calculating the C of G of my Glider.
As it has swept wings, the location is not so obvious (with straight wings C of G is roughly 25% of the Chord from the leading edge).
I used this calculator and my Glider subsequently flies well balanced.
