What is the engine brand that you know that have better durability? from your use or seeing others using

I don't see Saito on your list. If your talking two strokes I have a Webra 1.20 that runs as strong now as it did many gallons ago.

Hi Dave, I forgot, this poll is only for 2 strokes, many thanks !

I don't know what a a Chinaman calls his good plates, but he calls his good sailboat a "Junk"!

They don't use good plates here - they already sold them all overseas

I can believe that. Maybe you can settle the myth of the water swirling in the sink. Is it different in the norhtern and southern hemishere?

Actually - Yes it is true
China is in the Northern Hemisphere so the water swirls the same way as the US water does (CW). In Oz and other Southern Hemisphere countries it swirls the other way (CCW). I think this is why the Northern Hemisphere holds most of the worlds top RC Pilots (now there's a risk of a counter attack if ever I saw one) - The planes are mostly built here so they turn better in the Northern Hemisphere countries.

It just get's so confusing whenever I fly home for a break - I just don't know which way to turn

And when you're sitting directly on the equator, it doesn't swirl either direction--it just stays in the basin.

I don't have one of all the above brands of engines (and I doubt that many respondants do) so this poll is probably not a lot of use.

However, I do have a TT46Pro that's done over 300 hours and is only 200RPMs down on a brand-new one.

I've also seen a TT46Pro lose a bearing retainer and spit out a couple of balls from the rear bearing (they must have gone up the transfer ports and out the exhaust because when we took the backplate off they were *missing*) and that engine is still running as good today as a new one. Fragments of the retainer put a couple of *very* small scratches on the piston and dents in the head but a few runs on hi-castor fuel with a very lean needle and the compression came right back up to "as new" levels.

Of the dozen or so TT46Pros in our club, not one has had to be retired yet -- which is more than can be said for the likes of GMS, TS, ASP and a raft of other Chinese brands.

Our club trainer also has a TT42GP that spends as much time burried in the ground as it does flying through the air but, after four years of near-constant use and abuse, it's still going really strong and remains 100% reliable.

We've lost one SuperTigre 90 to piston failure (it fell in half) but the other 3-4 in the club seem to be going just fine.

Two OS46FX engines have been retired well before their time due to peeled liners but the AXs seem to be holding up okay, although they do lose power as they get older, while the TTs are still pulling strong as new.

We've lost a GMS32 due to being just plain "worn out" after no more than 10-15 hours. It was used with a tuned pipe however and may have had a lean run or two. Others have retired their GMS47s because they're just too damned tempremental when compared to the TTs.

It's interesting to note that, after at least 10 gals of fuel, my TT61GP is still so tight (ABC pinch) that an electric starter won't turn it over in winter when it's cold. By comparison, my ASP52s were also *very* tight when brand new but after less than a gallon of fuel they've lost all their pinch (but still run well).

Most modern engines are pretty damned good but if I had to choose I'd say Thunder Tiger for 2-strokes and Saitos for 4-strokes.

I'd have to say Enya. The early 29/35's have been around for about 50 years now and AFAIK no one has worn one out yet . The same should hold for the latest iron piston Enyas. I put several hundred hours on an old 45 before I fitted new rings. The AAC 60X just never seems to wear out either.
