Methanol Oxygen Carbon dioxide Water 2CH3OH(l) + 3O2(g) --> 2CO2(g) + 4H2O(g) This does assume perfect combustion though, and we arent going to achieve that very often. It's splitting hairs, I know, but in terms of mass the amount of CO2 produced is slightly greater than the H20. (RHS of eqn: 88 + 72 += 160 mass units = LHS). But still the point is well made that combustion produces lots of water (hence contrails from airliners). Quote Link to comment Share on other sites More sharing options...

Every comment i made was argued to the ends of the earth and it just became too tiresome. However, my top 5 list of common problems would be something like this 1. Modellers/Club 'experts'/Forum 'experts'/Youtube 'experts' 5.Tank placement You omitted Persistent fiddlers . Those that wont listen. Those that should never bet let loose near an engine of any type. And of course those that seem to come from the plannet Argue. 🙂 1 1 Quote Link to comment Share on other sites More sharing options...
Jon H Posted February 5 Share Posted February 5 Well i was working on the basis that my 'modellers' category covered your first two points, club and youtube 'experts' are covered by point 3, and the last...well, i will leave it to your imagination 😉 Quote Link to comment Share on other sites More sharing options...
