A ratio is an expression that compares quantities relative to each other. The most common examples involve two quantities, but any number of quantities can be compared. Ratios are represented mathematically by separating each quantity with a colon – for example, the ratio 2:3, which is read as the ratio "two to three".

IE: 50:1 would be fifty parts fuel to one part oil. or 2% oil by volume

No what I mean is that if you mix something 50:1 it makes no difference if you use liters or gallons, you still use the same ratio.

Might take a vast quantity of Tequila and Jagermeister to work that one out.

Very nice it is about time someone start building something different other then edge extra's and yaks.

The full size Sbach 342 is a very capable aircraft.
