Greetings Starbuck, I build planes in scale 1/200 with paper of 75-80grs, I learned to handle this very fine paper, at the beginning you will want to make a bun and throw it away, then you take care. It is more delicate, tends to To be dented before a slight pressure and it does not give you time to correct unions, when gluing you must be very careful. The advantages, cutting is very easy and when sticking you do not have to wait long to continue, it adheres quickly.
