Polini 303 fuel burn test - How did it perform!

How much fuel did I use in 1 hour. To fly further and for longer, understanding your fuel burn, a few tests need to be conducted. I tried to fly a typical flight for exactly 1 hour and see what the fuel burn would be. The link to the Polini website is below and it will show the fuel burn figures at 4500 rpm.

To best understand how their figures relates to real world, the NiNE at hands off trim ( fixed trim) is about 53 mph and requires 6300 rpm to remain level in flight.
The tank contained 16 litres before engine start and a complete flight cycle of Start, warm up, taxi take-off, cruise, land and taxi back in.
I frequently get asked about the kit I use, all links or names are below.
