Ok, so on closer inspection the diagonal stripe pattern is much more complicated than i first thought.
Forward of the exhaust the stripes meet every third one.
After the exhaust they meet every forth stripe, this is complicated again as the fuselage narrows and widens for the tail !
Stripes going backwards from the bottom will be slightly more straight forward than those going in the other direction.
Stripes are roughly 1mm wide and roughly 4 mm apart.
Hoping once i start the first few going in the opposite direction, it will be sort of intuitive where the next goes.
4mm strips of tape 1mm apart, how hard can it be
