I've also never seen lead outs exiting at the fuselage.
Well it痴 a joke.
But some CL planes do have lines exit the fuselage. Some OTS planes and my BiSlob.
Beech T-34 Mentor. 33 in span control line scale by Paul DelGatto, kitted by Berkeley 1954.
I also think the 1949 Viking has the leadouts coming out of the side of the fuselage.
You just haven稚 seen very many OTS planes.
