RE: Small mods to an Balsa USA Enforcer...
Thanks Soar,
You are correct in that if I add a larger canard, then it is no longer a true delta. I have a online calculator that will allow me to calculate the CG for a canard. It takes various measurements from the canard and wing (which the delta wing would be treated no differently). The main reason I want to add one of the two (or both) is that I do not like how the front of the wing enters into the fuselage along with the stubby nose of the Enforcer. The canards are cool looking (and can be functional if I choose) but I really like the idea of a more gentle blending of the wing into the fuselage (like the FA-18 Hornet). Also, what I want to add is actually called a leading edge root extension (again, like the FA-18 Hornet). Actually, I could just blend the canard and LERX together such as is seen in the SU-27 Flanker or SU-34 Fullback. I guess I could make several gliders with different configuration of the two and see how they affect the CG. Again, thanks for your comments!
Happy flying and soft landings!
