<div> <font size="2"><font face="Arial, Helvetica, sans-serif">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. <br>
<br>
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<br>
<br>
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.<br>

percentage of nitro. Nitro is the heaviest component. Don’t believe it? Go to
the 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 a
fuel manufacturer showed me at Toledo about twenty years ago. Fortunately, pilots
with glow planes are weighed without the fuel so they don’t have to worry about
that…</span></div>

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