Huh?...........Saito Fa-125: 21.87oz O.S. 1.20AX: 22.82oz
2.20Hp 3.10Hp
I think maybe what you mean is 2strokes have better P/w ratio?
But a 4 stroke Torque Curve is Flatter ,2 strokes are Fine, but the modern 4stroke has come a long way..........an ya gotta love the SOUND!

Saito 125 Total Weight: 24.69 oz (700 grams)
It's a marginal amount once you get to this size, but it is heavier. Although, I too much prefer a 4 stroke over a 2 stroke, and for all the same basic reasons; Sound, Efficiency, Torque Curve, etc... For a 3D plane, the only thing that trumps a 4 stroke, is brushless(excelent power to weight ratio while retaining smooth usable power). But, the outrageous cost of batteries for those systems is what keeps them out of most planes.

4 strokers are heavyer than the 2 strokers are.

To those of you that agree that a gassser will destroy this delicate airplane...kudoes to you...cuz it will! I have the old YS-110 (W/O the direct injection) and it does exactly what I ask of it (Except drop..Its too much wing area!) That YS will pull people from their graves! But anyway....my 2 cents!

I have a YS110 in my X100 and a 120AX in my UCD60.
The OS pulls the pants off the YS but that supercharged sound is the best on the planet.
