OK I got excited your right! a 110 will be too heavy but what about an O.S. .91 2-stroke? or else the O.S. 1.20 2-stroke. the 1.20 is the same size, w/ more power. but my concern is that I dont want it to be over powered wich I think it will be if I put a 1.20 on her.
You can go the OS91 2-stroke route or save some money and go for the Magnum, which seems to perform just as well.
OHH by the way, I herd that 2-strokes are better for pattern, and sport aerobatics than 4-strokes. and 4-strokes are better for scale, True-False???
I don't think you can really generalize that easily.
Some people say that 4-strokes are better for scale because they sound more realistic - but (despite the fact I love my 4-strokes) I believe they sound more like a lawn-tractor than any real airplane engine I've ever heard.
It really does depend on the airplane itself.
A 2-stroke does sound silly revving its guts out in a Piper Cub but then again a good 2-stroke can sound very nice in a fast Mustang P51D, especially if it's ripping the prop.
4-strokes win where you want a very rapid response to throttle such as for 3D flying. 2-strokes win when you want to save some money and want the bare minimum of maintenance and the maximum power.
The bottom line is that *any* engine is better than no engine at all :-)
