Check with Ritch's Brew. In the past, that is where I got my fuel. Some hobby shops stocked it but not likely to find it now at retail outlets.
Let's face the facts. Our hobby is on the endangered species list. The good old days are over. It is tough to get anything now. Balsa, fuel, and other supplies are expensive, if you can even find what you need. Without a place like Brodak, I would probably be forced to give up on this.
At a recent event at the RC field where we have a control line circle, I walked over to the RC area to check things out. I looked at the planes, either on the tables, being readied, or in the vans and SUVs. Most were foamie ARFs or RTFs. Electric powered, for the most part. Very few build anymore so why would hobby shops stock balsa and other building materials? With electric taking over, why stock fuel, or the components to make your own?
I am hanging on, hoping for the best, but the end is in sight.
