If you closely at the Bobby Hunt model it's got about a million rivets and panel lines
I guess as a result of his background in control line stunt since those models received points for quality and detail of finish. If a similar rule had ever been applied to F3A, the Japanese would probably have won a lot of WCs
The panel lines, access hatches, inspection plates, rivet dots and screw heads were added using a #2 Rapidograph pen just before the final clear coat.
