get the os if you can afford it. I have a Super Tiger 40. it does run good but the carb has a little to be desired. I dont have any experiance with the others. great luck with the os

RE: Choosing a 46 sized engine...
 

Of the 4 engines listed, I have use both of the evolutions. I find both of them to be very good, but I prefer the 46NT

RE: Choosing a 46 sized engine...
 

While I normally fly OS engines I did have the chance to use a Magnum engine in a review I did on the [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=745]Model Tech Mach Racer[/link] . The engine was the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXBUX6&P=ML]Magnum XLS 46 FSR[/link] . I was very impressed with this engine, and still have it to this day. I don't normally buy "cheaper" engines but this one made an impression on me and will definitely stay with me if I ever crash the plane. Take a look at it and see if it will fit for what you are looking for

I have 2 magnum's and both of them are great engines. Good transition from idle to wot. One on my scratch built "not for sale" and the other on a Ulta Stick 40 on floats. Paid 60 new.

RE: Choosing a 46 sized engine...
 

By the way they are 46 xls

RE: Choosing a 46 sized engine...
 

Don't foget the Thunder Tiger .46 Pro. Great running engine.

RE: Choosing a 46 sized engine...
 

I've used a magnum before. Definately worked better than I expected and I would not hesitate to buy one if I was short on cash. I would still by the os if I had the money though.

RE: Choosing a 46 sized engine...
 

I have had several of the Magnums and they are a really nice engine as are Super Tigre. I bought three of the Super Tigre 45s for smaller planes. Ran great! Most reliable one I ever owned was the OS .46 in my Nexstar but OS get a little pricey. If you are on a budget, adn we've all been there, buy yourself a Super Tigre 45. Those engines rock right out of the box and wear like iron. I bought three of them when I could afford OS. LOL

RE: Choosing a 46 sized engine...
 

I've got an OS 46ax on my mustang, that engine really hauls it along nicely. After 1 season on the engine, about a gallon and a half thru it, it tachs about 13,500 on a MA 11x6 on a nice cool day.

I broke in a Supertigre G45 for a friend last week, and I must say I'm impressed with it initially. I did find that the recommended 3 turns out on the HS needle was too rich to start it (try 2 turns or so), but once fired, it ran very well. On the same prop as the OS, by the end of the tank it was easily holding 13100, and it's not leaned out yet. Throttling response was adequate for a richly tuned engine, time will tell on this one, but my initial impression was very positive.

The OS has a nicer looking muffler, tho I've popped the thru-bolt on it a couple times now. If it's even slightly over-torqued, thermal expansion of the muffler pops the bolt. I'm out a baffle now (lost in flight), but all that did was gain me a couple hundred more rpm. Without the baffle, the engine acts like it's on a mild tuned pipe, really turning up in the air. Even after loosing half the muffler in flight, the engine performed flawlessly. This one has never deadsticked (knock on wood....)

The ST muffler is UGLY. It won't pop a thru-bolt, tho, as it's crimped together.

I've worked with numerous evolutions, the Trainer P(o)S, and the non-trainer .46. I find the trainer power system idle needle to be too sensitive, and too easy to turn (doesn't always keep a setting... This can be fixed easily enough, tho.). Idle mixture is key to good running in an evo, completely intolerant of mis-adjustment here.

The Evo's have an interesting styling with the upsweapt fins.

The only Magnum I ever owned was old, second hand and I didn't like it much. I won't weigh in on that one, I know they're popular with many and they're better to comment on them.

For my money, I'd go Supertigre, if OS was out of my price range.

RE: Choosing a 46 sized engine...
 

If you are new to engines I would recommend that you go with an OS. I have spent far too much time helping beginners solve problems with their less expensive engines. If you are experienced and enjoy working with engines them then by all means go for one of the bargain brands.

RE: Choosing a 46 sized engine...
 

I'll second the OS .46 AX. I only started flying last fall and the used Kadet LT40 I purchased to train on came equipped with an almost new .46AX. It is a powerhouse and I'm currently swinging a 12/6 prop and though we haven't tached it, it will still climb unlimited at nearly vertical. That engine needed almost no adjustment as the temperatures swung from summer into winter and it has never failed in flight. One of the seasoned instructors at our field was so impressed with the performance that he bought one for an ARF he was assembling and is having similar results.

EVOLUTION .46

RE: Choosing a 46 sized engine...
 

Well, the OS 46 AX ABL is the newest version of the OS 46 sized engines, and for $109 at Tower, this is a great buy, and well worth the few extra bucks you may spend on a less expensive (note, I did not say cheaper) engine.

I had an Evo 46 and it ran pretty good. I hated thier 61 and 100. Both ran lousy, when I could get them to run. But the 40 was a good engine.

But, after the experience I had with their 100, I prefer to stick with OS engines. I have several and all of them, and without exception, they all run like clockwork.

CGr.

RE: Choosing a 46 sized engine...
 

the OS 46 AX is really a great little engine for the price http://www3.towerhobbies.com/cgi-bin...?&I=LXFMD5&P=0
magnum not really that much cheaper than the OS http://www3.towerhobbies.com/cgi-bin...?&I=LXBUX6&P=0
again TT Pro 20$ http://www3.towerhobbies.com/cgi-bin...?&I=LXKF97&P=0
there all close in priceOS is also giving a small rebate and I do mean small but the cost Vs. product your getting a easy to run( tune,break in,and reliable running qualitys)for the small extra your going to pay,I am a bit biased since I am a OS fan but the product speaks for its self.

RE: Choosing a 46 sized engine...
 

The TT 46 Pro is a great engine. I'm running one on a Sukhoi and it's been very reliable, holds a nice low idle and transitions quickly. The Price is right as well.

RE: Choosing a 46 sized engine...
 

sdg666, you are thinking about this a little backwards maybe. Get the best engine and radio you can afford. Reason being they are the investment part of the hobby. The planes will change as you progress. So if you get a quality engine you will likely use it in 5 or more planes. If you get a turd engine you will likely have at least two different engines in your plane.

RE: Choosing a 46 sized engine...
 

I gree with Mr67Stang.
i would get the O.S. 46 AX or TT 46 pro

you get what you pay for.

RE: Choosing a 46 sized engine...
 

Since no one mentioned the GMS , I`ll give it a shot. I have a GMS .47 with the large expansion muffler. It was hard to tune the first few tanks, once tuned in , the power and rpms it puts out is unbelievable . I dont have a lot of run time on it , so I can`t comment on durability .

The OS .46 AX is a great engine for some one who does`nt have much experience with glow engines . Very easy to break in and tune.

Evolution engines are great if you get a good one.

SuperTigres are my favorite for any size 2 stroke. lol

RE: Choosing a 46 sized engine...
 

Robbie, that sort of implies that the OS 46 AX is only good for beginners and that experienced people would do better with something else, which I am sure you will agree is just not so. My pattern friends, one of whom has been flying for over 36 years, flys pretty much with OS engines on his pattern planes, and highly recommends the OS 46 for anyone that would ask, regardless of experience.

I've never tried GMS, but I am sure they are fine engines. One of the guys I fly with has one and loves it.

Cheap engines and expensive engines both actually run well once they're broken in and tuned properly. Expensive engines hold together better over the long haul and usually don't require minor maintenence as often.

My O.S. Max engines (2 .46 FXi and 1 .46 FX) bolt together then stay bolted together and then they just run and run. They also break in and tune easily.

My GMS .47 engine took longer to break in but ran like a scalded cat and transitioned great. The cylinder head bolts worked themselves loose while the engine was in winter storage though, and I've never had that happen with other brands.

My Magnum XLS .52A had an air leak in the remote needle valve out of the box. I moved the needle valve to the forward position and it ran fantastic ever since.

My Thunder Tiger and Super Tigre engines have been terrific so far, but they have low run times thus far.

The O.S. Max .46 AX is worth every penny of the $109.99 selling price that you'll typically find it for. If you'd rather spend less, you can certainly do so and still get a great engine, even while saving $40 or $45.

If I wanted to buy the best .46-size engine I could for the least amount of money, I'd buy either the Magnum XLS .46A for $69.99 or the Super Tigre G-45 ABC for $64.99. The only knock against the Super Tigre G-45 ABC is the heavier-than-normal muffler. The GMS .47 is also an outstanding value at $64.99. I'd skip the remote needle valve version for easier (though more dangerous) and more reliable tuning; it's probably the best choice for maximum speed.

Interestingly enough, the Evolution engines are manufactured in China by Sanye, the same company that manufactures the Magnum engine line for Global Hobbies. GMS manufactures the GMS, Tower Hobbies, and Super Tigre engine lines in China. Each brand is manufactured to different specifications however, and it doesn't necessarily follow that the Evo line is the same as the Magnum line or that GMS engines are the same as Super Tigre.

Nobody has even mentioned the Aviastar .46 BB ABC engine available from Sig for $59.99 or the SK .50A at $59.77 and the JBA .46A at $69.95 both available from KangkeUSA. All of these engines have fairly good reputations for quality as well, but suffer from more limited distribution.

The MECOA Aero .46 avaiable from www.mecoa.com for $79.99 or $59.99 with trade-in is also a terrific, screamingly fast ball-bearing engine. MECOA also sells a number of K&B engines like the .46 Sportster and the Screamin' .48 in this size range.

You could buy an O.S. .46 LA for $69.99 and get a top quality engine even if it's not the most powerful one in the size category in question. The $49.95 Super Tigre G-40 ringed engine is a steal for the price. The Thunder Tiger GP-42 is a top quality plain-bearing engine in the $59.95 to $62.99 price range; it's often overlooked because shoppers assume it's similar in power to the O.S. .40 LA when in fact it is much stronger.

There are so many great choices in this engine segment that it's hard to name them all. Anyway, like I was saying, I'd probably buy the Super Tigre G-45 ABC...
