RE: ax 55 problems
Stunt-man,
Foaming is not the problem...
It is the vibration of the tank walls that cause the clunk to be deflected off them, into spaces in the fuel-tank where air resides; in turn causing this air and gaseous methanol to be ingested into the fuel line...
No matter how strong the vibration level is, glow-fuel is not milk-cream that one can churn into butter...You cannot churn it into a thick, rigid froth, that will prevent the clunk from sinking rapidly back into the drink...
Formation of a tankful of 'fuel-foam' only requires a very small amount of liquid fuel, that will not significantly lower the level of the fuel.
