Keep in mind that I am slightly autistic WRT numbers, so I measure...Maybe not with the accuracy of a swiss clock, but still...
I am guessing your engine consumes about 200 ml with 15 minutes of your flying style, mine does that with 8 consecutive tows, which all things considered is not that different from your typical "15 minutes of flight". I would not worry about it, because I can assure you, these engines are fairly consistent WRT fuel consumption, and would it really be guzzling, you would allready have complained about the humongous amounts of crud on the plane...
glugy mess eww thats one reason i like petrol power , is definitely the saito fa120r3 waco needs basically no cleaning. I might clean it every second weekend, and the boxer well after 3 10min flights the bottom is easy to clean,thats including the crank vent exiting at the same point as the exhaust tips so im rather happy with that, once i get some hose nipples to fit in the rocker covers that will then reduce mess underneath the plane, yes i wasn't overly worried about my fuel consumption as i bet it will use double with methanol
