morgy Posted February 25, 2017 Share Posted February 25, 2017 4.5-5 lph on fast rims is not that bad for a small engine.. most figures are gain form 30kg static thrust on a test bed.. your best eco figures will be gained by flying on slow trim settings.. your KM per Litre will also be much better on slow! Our Mac Fly Thor 80cc is 21-22kg all up and has the small PWK carb, these are much better for tuning and your eco figures.. Quote Link to comment Share on other sites More sharing options...
