Default 4stroke vs 2 stroke

I am trying to get back into this and am trying to decide on an engine. It was reccomended to me to get a four stroke if I could because they are better. What makes a 4 stroke better? Sorry if this has been hashed out before.

Done to death a zillion times. Do a search.

Not "better", just fashionable and (usually) more expensive. Ergo advocated as "better" by those prone to the dictates of fashion.

Define "Better"

A 4 stroke is 2-3 times more expensive, heavier, more complicated and if you are prone to crashing - just keep to a 2 stroke...

BUT
A 4 Stroke has much better power, uses less fuel, lasts a long time (if you take care of it), works very well inverted and sounds great.

Yep! it's very much a matter of opinion...
BUT if you are just getting back into the hobby and you are going to crash a bit... get a good 2 stroke- 46 - 52 size will be plenty!

YA this one has been beat to death. No one is right. It's in what you want. I like them better, they idle smother and less finicky on there settings. That's an opinion, I have no problem adjusting either but I rarely is ever have to keep playing with the needles on my 4 strokes. If looking at the specs they may appear less powerful since the HP rating is lower. They make up for it on torque. If you want speed a 2 stroke will out perform it. A 4 stroke will out pull a 2 stroke on verticals. For 40 sized sport models a 4-stroke is something of a novelty. I use them on my scale stuff elusively mainly because they offer more torque in th mid range and they sound more realistic than a 2-stroke.

There was a long thread under this exact same topic in the Engine Forum.

More torque, yes. But better power? No.

Two strokes sound great too.

Personally i feel it really becomes a matter of personal taste or application. As said more torque from a 4st so bigger prop. Some planes tend to build tail heavy and a 4 stroker helps out there. Some planes are meant to be flown fast and there a 2 stroke is better. I run both and like both for me its just a matter of what i want from that plane.

I'll agree that four-strokes last longer. Maybe this is simply because most 4-strokes are ringed and most 2-strokes are tapered bore. OS 4-strokes seem to last forever. OS 2-strokes seem to last for only 2 or 3 years of heavy use.

I use 4-strokes much more than 2-strokes, but you really can't make a blanket statement that they are "Better".

They are better for some applications, but there are still times that I prefer a 2-stroke.

For getting back into flying, choose an engine with the adjustment needle behind the engine. That's pretty much every fourstroke, and some of the twostrokes. Keeps your fingers away from that knuckle-eating prop.

Both are quite suitable, but there is a difference in price. I think you might want to choose one of the less expensive engines, for now.

Good luck,
Dave Olson

Ya pays yer penny & makes yer choice. Too much folklore on either side -- most of it not quite right & some of it wildly wrong.

They both work VERY well.

If you can afford it, try them both. If you can't afford to do that, IMO you would most likely be better off with a 2-stroke.

You can't lose either way.

Those who hate 4 Strokes will agree with this:

Those who hate 2 Strokes will agree with this:

The rest of us simply fly what makes us happy.
