Hello Lem
Well I am flying a CA Models Eclipse with a 3M 170 and apc 17x13 prop, stock pipe.
Using a tetra 20 oz tank and 15% coolpower fuel, I can fly about 2 full sequence PO5 pattern.
Still having problem with setting up the engine ( overheats a lot and glow plugs keep coming loose )
Right now I switch over to a Ys 140Dz to compare the 2 engine in terms of power and fuel consumption.
