Hello ! I will get my Q1 soon but wih over sized Rotax 503
I want to come back to an economic ,quiet fly
Have some experience about replacing by one of these new 1 cylinder 4 strokes?
they claim fuel consumption as low as 2-4l/h !

I'm considering this as a solution for Quickie Q1
they are ligher engine (about 45lbs with reductiion vs 85 for 2 cyl)
which sort of prop should I order ? GA210 are ready to propose 1500$ kit with personalised reduction and propeller ! help me to find diameter , pitch , reduction for this [0-8200]rpm and I will test for you !
and on the opposite was also looking diesel alternative with new 3/LC B&S from
18hp to 34 (with turbocompressor) , 3 cylinders , same mount
DM 700D (18 hp) to DM 954DT (34hp Turbo) from 180 to 196 lbs
edit : reading the post VTwin chiese suggestion seemed more adapted , like 22hp / 58kg / SKF bearings / 3600 rpm (no reduction needed)

300g/kW.H means for 1.2L/G diesel 0.3*1.2*10 = 3.6 L/h of diesel 1hp = 1.341 kW (10kw=13hp , being 65% cruise power?)

would these industrial engines use vegetable oil (with preheating system) ?
anticlockwise means use of normal or inverted propeller? is nominal rotation direction a problem?
happy that I found this forum
