[NSRCA-discussion] This email list is flawed in my opinion.

 Yes that's true. When I was mixing my fuel I needed to do it by volume until I figgered what the volume weighed for each of the nitro blends I was mixing..... 30% nitro is around 10% denser (weighs around 10% more for a tankful) than 15% nitro. 

Soooo....the guys who are running the YS not only use much larger tanks but their tanks weigh more when full than they would have running lower nitro. But YS is a dawg on lower nitro. You gotta admire YS Marketing strategy

Yet another reason I am looking into gasoline powerplants for pattern. Gas is significantly less dense than 30% nitro blend and gas engines demand less fuel to begin with. A 320 cc tank (around 11 ozs) will run the 30 cc engine for around 12 minutes, enough for about 1 2/3 master schedules.

The weight of fuel is going to depend in large part on thepercentage of nitro. Nitro is the heaviest component. Don’t believe it? Go tothe hobby shop and pick up a gallon of 5% with one hand and 30% with the other,preferably from the same manufacturer. You’ll be surprised. I know I was when afuel manufacturer showed me at Toledo about twenty years ago. Fortunately, pilotswith glow planes are weighed without the fuel so they don’t have to worry aboutthat…

About 0.75 oz per fluid oz.



I just weighed a gallon of fuel I have here. It was 7.8 pounds including theplastic jig. 0.75 ounces per fluid ounce would mean the jug weighs +/- 29ounces (1.8 pounds).
