TT - Unfortunately you don't do panel lines on balsa/tissue planes. You can
do the lines on control surfaces one of two ways. Either with very thin color
tape, which hobby shops sell, or with a pen and ruler. I am going to opt for
the thin black tape.... it's easier for me to make a straight line that way.
This has been my complaint.... details on a balsa model are lacking. I don't
dare try to do weathering ! Looks like my FW-190 just rolled out of the FW
plant.... a pristine airplane, ready to be ferried to the front.
