This would be a pretty good sport fuel for any lapped-piston plain-bearing engine. His price was $10.85/gallon. And the price would be tough to beat anywhere. Shipping would add to your cost, of course.
PowerMaster makes good fuel, too, and it's widely available in various formulations. SIG makes good fuel, also, and is available in many hobby shops. The main thing is to make certain that the fuel contains enough Castor Oil for old Fox/McCoy/K&B engines.

You could run a 50-50 blend of castor and synthetic of you are using ABC type engines or some of the ringed engines, and here I would recommend about 22% total oil.
All in all your cost savings are going to be mostly in shipping, and if you have to ship the nitro you may be just as well off to have it mixed for you. If you are willing to get 6 cases or more (we usually get about 10 cases at a time) it is cheaper to ship by truck than UPS with their hazmat charge.

The propolene Oxide was probably the ignition enhancer. That's a bad guy now. A defoamer is defnitely a good idea and I thought of that as soon as I posted the last post. Even with the commercial fuel you sometimes need to (or should) add a couple of drops of defoamer. I remember when I used to get my fuel mixed at Red Max (which I no longer do due to their poor castor) they would normally add one drop to a gallon and I would have them add two. But two drops of Armor-All will usually do the trick. Do not add squirts, ou are adding water into the mix. We have it in a little drop applicator bottle. One 2 ounce bottle is probably a life-time supply, even with the amount of fuel we use.
You are right about nothing being easy. If you don't have a local hobby shop who can order what you need, you can go to a mail order supplier, and some of these will mix exactly what you want. We get ours from Rich's Brew and he will mix it exactly the way we want it. Buy it in a case of four gallons and pay the hazmat charge. Some places will sell it in quart bottles to avoid the hazmat charge, but, would you believe, the additional cost of packaging it that way more than exceeds the hazmat cost savings. Compute your total cost on the basis of the amount of product you are receiving and the total cost of shipping. You will see.

Your mentioning Red Max's poor castor oil made me recall a recent experience. I purchased fuel (normal SIG Champion, 20% 1/2 castor, 1/2 synth) at SIG for the Oct. 3rd Jerry 'WHO' Memorial sport race. We run Fox 35s so Glenn Lee added castor oil, from a pristine can of 'Francisco' castor oil, to each gallon of SIG fuel . This had to be 1960's vintage oil. The castor oil was CRYTAL CLEAR! I have never seen castor oil that clear, except perhaps medicinal grade.

Remember, you really only need two tools: WD-40 and duct tape. If it doesn't move and it should, use the WD-40. If it moves and it shouldn't, use the duct tape
VP Racing Fuels has a distributor in Spokane. I generally have competition-oriented motorcycle shops order nitromenthane and sometimes methanol along with race gas for the bikes.
Shipping can be a killer, but if they incorporate my needs into a gasoline order, it's manageable.
You might want to simply drive on over and buy it direct. Or not...
Wait, there's a drag strip in the Tri-Cities now, right? There ya go, start calling speed shops.
Incidentally, somebody listed PAMPA members in your area, this including my father Dean Rutherford. Dad no longer flies CL models.

70% nitro,10% propylene oxide and 20% 62RM is the hottest fuel you can mix and, makes a great 1/2a fuel.

I have flown hundreds of gallons of home mixed fuel, not only to practice, but for competition as well including the World Championship where I took my own home brew.
Mix equal parts of castor, synthetic (Klots), and Nitro. This mixture I called "concentrate". It is a 10% nitro, 20% oil mixture. To mix fuel put 36 ozs of concentrate in a gallon container and top off with methanol. I tried prop, lubricin and other additives but consider all of them unnecessary. All you need for good fuel is oil, nitro and methanol.
