RE: AVOID THIS ENGINE AT ALL COST!!!!!
I guess a lot of how an engine runs and idles depends on how we tune it. I got a little SC46 for only USD60 and she is perfect, does not dead stick on me and runs well inverted. That SC is a lot cheaper than my TT46. I've seen guys who do not tune their engines properly and they are not hitting the max revs and their engines are too hot to touch when they have landed. What can we say ... of course there are some lemons.

RE: AVOID THIS ENGINE AT ALL COST!!!!!
Ironcross, the Magnum 1.20FS, being a shameless copy of the OS 1.20FS, weighs very close to it. 31.5 Oz or something like that. IIRC, the Saito 1.20 is actually a tad heavier, not much.
The Saito 1.00 beats all three 1.20FS on power-to-weigh ratio, hands down, and probably a better bet for your 66" Extra. Don't know which one you are refering to, but it sounds like a .60-.90 size bird. If so, the Magnum is not such a bad choice either, especially if it need nose weight anyway. It's not really a fair comparison. It only make sense because their street price will end up being about the same. The Saito 1.00 might pull close to the same max RPM on some props, but the 1.20FS will still has a fatter powerband and, therefore, better all around tractable power, IMHO. The extra bit of cu. in. aren't just there for the ride, you know.
I would get the plane first before deciding. If it seems like it should balance fine with the Saito 1.00, I'd go with that. Lighter still flies better.

Thanks... I have the plane, it's a Vector Flight 66" Extra.. I am looking for plenty of vertical and don't need a lot of nose weight..
I was thinking a Magnum 1.20 originally but after doing some reasearch a 1.20 may not be the way to go.. Going from a Saito 100
to a Saito 1.20 it seems I gain .3 horsepower and around 12 ounces in weight.. Not a good plan IMHO.. Currently thinking of a .91
two stroke... Maybe a ST G90 or something.. Still undecided...

RE: AVOID THIS ENGINE AT ALL COST!!!!!
You guys are not reading all of the words re. the OS .40 LA thing. In my original post I said that they WERN'T bad engines, just gutless & not worth the price. There are several usefully cheaper engines that work every bit as well as the OS .40 LA, but are substantially more powerfull (TT.42 GP comes to mind -- even out-powers the .46 LA, despite a lower advertised HP) -- hence, the .40 LA is not worth the price & should be avoided. I have owned both a .40 & .46 LA & they ran very well -- but couldn't pull the skin off a grape.

40 LA in my 6-1/4 lb (no fuel) Coroplast LC-40 (Spad) plane. No vertical, no 45 deg. climbs, but it flys. On it's 3rd year. 2 deadsticks. (my fault - top end too lean) 10x6 APC prop. No complaints about this engine.

RE: AVOID THIS ENGINE AT ALL COST!!!!!
I started out with the Superstar 40 3 years ago. Still have it. Copied trim scheme from it to the Spad.
Allergic to balsa wood. (knees and hands start shaking after about 3 minutes of flying) Probably would not have soloed with the balsa plane. Built the plastic plane, (tank), pucker factor went away, successfuly soloed. Yea!

Seen fellows with K&B's and they always have trouble. I stay away from them and can't recommend them.

RE: AVOID THIS ENGINE AT ALL COST!!!!!
I have a Magnum .46 and it runs great, it has all the stats of the OS .46FX. I have never had it quit running. I have it on a KAOS. It will pull unlimited vertical until almost out of sight. I also have the Tower .46, this also has been a great engine once you open up the idel vent hole in the front of the carb. It idles real slow and steady now. And let me add one more motor that is cheap but runs strong and is very reliable, the Thunder Tiger .40 and .46.

RE: AVOID THIS ENGINE AT ALL COST!!!!!
Every engine listed on here as having a little trouble has been well defended by others who claim it is good. I am beginning to think that maybe there is no such thing as an engine that should be avoided at all cost. I am beginning to think that maybe all engine manufactures turn out pretty descent engines accept for an occasional bad apple that slips by QC every once in awhile. I am beginning to think that maybe some people just know how to tune an engine in and some people don't. I am beginning to think that a lot of the problem lies with Pilots not reading the specs on an engine before they buy. Like expecting a .40LA to produce as much power as a .40FX, and then being dissapointed because the .40LA won't pull there Plane Verticle. Or someone running an engine way lean over a period of time, and blaming the manufacturer that the engine they bought is crap because it wore out in six months. I am beginning to think that we, including myself ought to take more time to research a product before we buy it. Know what that products limits are, and its strong points. Money plays a factor in most products, and the old addage probally applies in this case also. You get what you pay for. Cheap engines can be good for the right application, but if your expecting a $60 .40LA to pull your .40 size plane verticle then you are really going to hate this engine. If you are wanting an inexpensive little engine that pulls your .40 size Plane around nicely, and is dependable then you will love this engine. It all comes down to the right selection for the right application I think. What do you want your Plane to do? Someone please correct me if I am wrong. I started this thread to find out what engines are CRAP! So far I have not been convinced that there is one single engine that is crap by a majority. Is there not one single engine to avoid at all cost?

I'd say K&B has the worst track record according to this thread. Not user friendly at all and yes I do know how to tune an engine

The 2 needle k&b carb sucked just like the old magnum carbs. The new K&b carb works like a perry carb and eliminated all the "user friendly" problems. When was the last time you bought a K&B??
The twist .61 is 100$,has 1.8hp and at only 18oz with muffler.

I have a K & B .61 Twister and it is an awesome powerful motor. It turns a 13x6 Master Air Screw Simitar prop with authority. I've quiet a few K & B engines and I've had very good luck with them for over 30 years. The K&B Sportster series are all very good running engines and run them all on one model or another. Inexpensive and good running. And if you are lucky enouh to have a C.F. Lee reworked K&B, you are in for real surprise.

Try another thread. There are many K&B fans. The only problems I am aware of are with the very early Sportsters without the crankshaft bushing. (I think a new bushing is still available at moderate cost to correct this if you have one of the old ones.)

RE: AVOID THIS ENGINE AT ALL COST!!!!!
Very good post ckangaroo- I believe you have hit the nail squarely on tyhe head. A quick review of the thread reveals that if we avoid all manufacturers to be "avoided at all cost" our selection is quite limited! I think perhaps Jett and Enya have avoided the dreaded title

RE: AVOID THIS ENGINE AT ALL COST!!!!!
CK you are most correct, some lemon engines and people who do not know how to tune or treat an enine will swear its not a good engine. I know of some people who say OS is the only way to go and not to buy cheap China made engines are lousy etc etc etc. I bought an SC46 (ABC) for like USD65 and after 4 few gallons the engine still runs fine and idles decently (I have not spent time to make sure the idle is good). All engines have their own quirky habits, some people at my airfield expect to run a Rossi hard after like 3 tanks of running in (at high RPMs too!). Only engines I hear that are lousy will be something like your LEO, other than that all have been pretty good.
Anyone who expect an LA40 to pull verticals better stick it into a 15 sized plane!

RE: AVOID THIS ENGINE AT ALL COST!!!!!
O.S. = "Oh Sh**" LA = "Lousy A**" engine! But in all seriousness, the real engines to avoid would definitely be the "Tower Hobby" .40's and the like... These are "Hit -or-miss" engines, the quality control is so low, that you never know if you're getting a good or bad one. I have two, "came with a whole bunch of stuff from a personal sale" One of them tower hobbies .40 works great, the other one just dies in th air, even after a great test run and warm up on the ground. I've broken a really rare on-of-a-kind plane because of it... I just cleaned out the carb, and seald the carb to the frame, and am going to try it again, but I don't know if it'll work... I hope so.

RE: AVOID THIS ENGINE AT ALL COST!!!!!
tIANci, I have a couple of LEOs (.46 Pro & .61 Pro ) & they work really well. Not quite as powerfull as a TT Pro, but ever so much better than an OS LA, & they cost about the same as the LA. The LEO quality is good -- noticeably better than the MECOA .46 Tomcat that I have & they start better than the MECOA & nearly as well as the TTs (which I find to be exceptional starters). I would certainly choose a LEO rather than an OS LA (I've owned both the .40 & .46 LA).

Ok ... Leo is not that bad!!! Yeah its under powered. Just that in Malaysia there is hardly anyone selling an LA, the standard is your TT46. Entry level!
