Hello everyone! As you know from the topic title I'm building a 1/200th scale jet,an F-4 phantom II in Israeli markings. Now I'm building it so its on a tarmac so I will need to know what is the best way to make these remove before flight tags in 1/200th scale? Is it possible? Please help if you can!

If they are half a foot wide and four feet long, that would be .030" x .240". that's manageable.

You can get some 1/32" decal stripes from Microscale

spray them with krylon clear stuff, let that dry, cut them out and put them in water, float them off the backing, then hang them up to dry. Then hit them with krylon again on both sides. that will make a very thin, fairly sturdy and stiff red film. cut them into 1/4" lengths and then figure out how to attach. maybe Ailene's tacky glue, applied with a needle.
good luck. post pictures.

As a rule, RBF tags are 36" in length, and about 5 inches wide. Don't worry about the writing on the tags, you wouldn't be able to read it anyway...
