Hobby Shack, which later changed it's name to Hobby People, was my source of Powermaster fuels for 30 years. When I needed a gallon of FAI fuel I could go to my local Hobby People store and grab it off the shelf.
Now that Hobby People is out of business, the two hobby shops that are left within 20 miles of me that I am aware of, do not carry FAI fuel.
You guys who still fly glow engines at the basin, do you know of a source for FAI fuel? Smith Bros and Robin's Hobby do not carry it.
