Sometimes, glow fuel is called '''[[nitromethane|nitro]]''' or just '''model fuel'''. Some model fuel has only a little bit of nitro, but some fuel has none at all. It is called "FAI fuel." "FAI" stands for [[Fédération Aéronautique Internationale]]. They say that models used in racing or other competition under their rules may not have any nitro in their mix. | Sometimes, glow fuel is called '''[[nitromethane|nitro]]''' or just '''model fuel'''.
