Yeah, around january our culture program holds a big kite festival, I made some invisible fighters and caused some mass damage to other fighters, they provided us with glass thread which was great but I need to order better quality from India. What winds do you fly 7 inch kites in.
It is pretty dangerous to fly a fighter with other expensive kites in the area but, I went to walmart and bought some drop line which isn't the best but it gets the job done for kite line, I flew my fighters at the big kite festival that is hosted by ABC every year in Austin.
Fighters can also achieve breathtaking heights, During the kite festival (which is a plane free zone) atleast the one hosted by my cultural program, we tied like 9 spools of thread together and sent a kite ultra high and managed to bring it down without it breaking, fun times.
