    Hi, I am trying to see or find a way to improve my fuel burn L I know the 582 and the X-Air are not that fuel friendly but I have been reading and could see that there are people out their flying the same machine and are having better fuel burn than I currently have !

    My current setup.

    582 Mod 90 with a B box and a Warp Drive 3 Bladed prop pitched @ 11.5 degrees

    Current hourly consumption is 20-21 ltrs and hour flying @ 5400 Rpm and cruises around 50 – 55 Mph.


    Any suggestions welcome..


    Thx

    Install a mixture control. One option is the HACman from Green Sky Adventures: HACman FAQ

    With the correct jetting on your carbs, this allows you to dial in the optimum EGT (usually about 1150°F) for whatever RPM you're running. Typically your prop will be pitched to give you 6200 - 6300 static RPM at full throttle. Then the optimum cruise RPM will fall around 5800 RPM on the 582.
