Thank you both for the good input, I will use the calculator
and see what I need to set it at. I was wondering if using a
canard configuration would affect the calculation as would a
tailed configuration? Any ideas? Thanks again and have a great weekend.
With a Canard the optimum CG will move forward, with a rear mounted stabiliser it moves backward. There is a CG calculator for conventional 'tailed' aircraft here: http://adamone.rchomepage.com/cg_calc.htm
. these also work for tailless, simply put tiny values in for the tail area and moment arm
