rotax 503 fuel use

[cdlwingnut]

those who have or are flying with a rotax 503 what is your average fuel burn
I am putting one on my project and have a 6 gallon fuel tank, I am not sure if I should add another tank or not

[George Sychrovsky]

Two strokes like Rotax burn 0.1 gal per hour per HP that means 503 at normal 75% power setting will burn 4 gal per hour
