Ahhh, maybe there's been an 'improvement' made to RCU. We used to get '*POST REMOVED BY MODERATOR*' but now we just get left wondering what people are talking about..

DarZeelon,
Thanks for the clarification...

O.S. stands for Overpriced S--t. Look at the TSI .40 At www.kangkeusa.com. I have two and they are super. Also check out the MECOA .40 at www.mecoa.com. Both are BB ABC engines and cost about $60.00. Irvines are nice (I have three, a .40, a.40 diesel and a.21) but they are simply underpowered compared to most. The best for the money, in my opinion, is the Enya. They are bulletproof and I have a few that are twenty years old and are still strong.

Good Luck,
Max

Having flown this plane with a 46 and a 50 before, i would recomend a 50 somthing for it, really gives it a bit more life. Just personal peference.

I went the cheap route ONCE, and bought a TSI .40. It was the BIGGEST mistake I've made in my R/C hobby! The piece of junk cost me an airplane, so from now on, I'll stick to the "Overpriced S--t", as Maxtenet calls O.S. I have NEVER had a problem with any of my O S .46FX's.

I gotta ask Angel, was that the old T.S. with the red head? I run one of their 52's on my S.E. and it has better performance than the Webra 50 I had on it and I can fly for 23 minutes on a 8oz tank of gas. I also have one of their 46's and it's hard to tell any difference between the two engines power wise, now these are the new ones with the silver head and for the price are some of the best 40 to 50 size engines I have ever run. I paid around 60 bucks each and have allready gotten my money out of them (twice). Price aint always everything, Kangke/Tiger Shark sell a great product at an even better price just look at their arf's, and customer service is second to none. Did you send your 40 back? If you didn't you should have, they would have made it right to you, and no I don't work for them I just don't see many people talk about their engines that by the way he could get two of for 120.00 bucks.

Wow, 23 minutes on an 8 OZ. tank and more power than a Webra .50, that is some engine.

Rockmon, yes it was one with a red head and yes I did send it back to them. They had it for about 5 weeks and sent it back. I'm not sure what they did to it, but it didn't look like much. *IF* they cleaned it, they didn't do a very good job, because it didn't look much different than when I sent it in. They were going to replace it with a new one, but were "out of stock" "and didn't know when their shipment was going to arrive."

Someday I will build a foamie and try it again. At least when it dies, it won't take the plane with it...

hobbsy, yes 23 minutes but you have to know that most of that time was at or below half throttle. With my Webra to hover I was at 1/2 to 3/4 throttle to hover my S.E. with the T.S. 52 1/2 throttle will make it jump out of the hover like a rocket, believe me had I not seen them run and then ran one myself I would put this in the big fish story catagory too but it is true. I'm re-doing another of my S.E.'s and am trying to lighten it by a half pound, it will get the T.S. 46 and if I don't like it I'll buy another 52. The Webra is one of my favorite small engines so I'm not really knocking it but I will never spend 160.00 for a 50 size engine EVER again. I run both engines on 11.5x5 bolly's and 12x3.75x5 APC's and the T.S. outdoes the Webra on either prop, now I wouldn't put it up against the Webra on a pipe on a good high speed contest but for pure pulling power I would take the T.S. in a heart beat over the Webra, and my Webra would suck that 8oz tank dry in a 10 minute flight even at half throttle.

Hey Angel,


I have 12 O.S. engines as a collector and user. I don't know if you got a bad TSI, but I still say they are the best engine for the money. The O.S. .46 and .40 are very average but run out of the box. They are the Ford or Chevys of the engine world, Perhaps this is why they are popular. With a little tuning knowledge and proper break in there are many better alternatives.

Max

OK Max, if OS is the Ford and Chevy of the engine world, then in my opinion, the TSI is the KIA. Some people chose to drive a KIA and after 50 to 60K miles throw it away, while others like me prefer to drive a FORD for 200K + miles and still going strong...

The EXTRA money I spend on an OS is the *insurance* policy of MY hobby world. A *premium* that I'm happy to pay because I believe that OS IS better that TSI...

Doug

I am thinking the OS .46FX is best for me. Provening quality and performance, fairly light even with the muffler, Great power to weight ratio, good warranty, and within my budget for a new engine.

Jason

Why buy an OS FX when there are so many better and cheaper engines out there? I mean they are good engines, but say a TT .46 is slightly better and cheaper to boot.

Jason,

Something you cannot say about the .46FX, is that it is light and has a good power-to-weight ratio, especially with the muffler.

There are engines out there, that run like Ferraris AND last for 200K miles AND are gazelles next to the OS.

They don't even cost more.

I have not found any quality control problems with Fox, they do need a long break in, especially older ones, but a couple of newer
Fox's broke in rather quickly. They also have had some carb design quirks but that is solved now. In fact the Fox .60 was the best .60 engine in the MAN shoot out.

There are a lot of myth's out there even amongst knowledgeable modlers, one of them is that OS is top quality and Fox is the worst. IMO Fox has better quality control than OS but some of the carb design is not as refined, however they work fine. I have a Fox Eagle I .60 that they quit making in the late 70's. I bought it with a Perry carb because I was told that Fox carbs were crap. I quit the hobby for 15 years before actually using this engine. When bench running I couldn't get the engine to run right. High end was all the way out and idle was practly at full lean, still wouldn't transition well. Well doing some horse trading I ran into a period Fox carb and bolted it on. It ran great ! I only had to adjust the high end I didn't have to touch the idle. Runs at 12,500 RPM with 5% nitro. This is better than my K&B .61 of the same period! Pretty good even today condidering its just a cross flow baffled piston engine.

The Fox .46 is much more powerfull than the OS FX .46, but you may want to buy a seperate muffler, the Fox muffler is too loud.

Don't buy the OS FX .46, my favorite knocking around .46 sized engine is a TT .46, its slightly more poweful and a lot less expensive, and maybe a bit more reliable. IMO only a few OS engines are worth the price. The 1.6 FX for example.

Also hobbsy is probably one of the most knowledgeable posters on this board. I don't dissagree with him very often.

You are right, because of the mufflers OS practically invented the "fairly heavy" engine. Good engines though, just overpriced.

I'd suggest the tt46 pro ,best bang for the buck. people used to complain about parts availability, however due to increasing popularity most hobby shops carry the typical carb parts etc.

the 46fx is a fine, fine, engine with plenty of power. I have 3 and wouldn't trade for anything. even after sitting for a year it fired up on the first flip! the only thing I don't care for is the stock muffler. I went to a mac pipe on allof them after losing the aft section 3 times. but of all my engines I have they are the most reliable.

The Thunder Tiger seems like a very attractively priced engine.

That is, until you need to replace the piston/sleeve combo.
A set costs about 90% of the new engine's price ($68, I am told).

You could call the TT a "disposable" engine.

Use it - Trash it.

According to Tower Hobbies:

TT .46 = 1.43 bhp and 17.01 oz w/ muffler
OS .46FX = 1.62 bhp and 16.45 oz w/ muffler

Hum,

Jason

If you can spare the weight and only 89 bucks:

MDS .58
Weight w/ muffler:
19.48 oz
HP:
1.72

We all know HP figures are kinda inflated anyway...

True, I am sure .

jason

I had considered MDS .58, but I did know anything of the quality. My LHS wouldn't recommend one.

The Super Tigre .40 I am replacing is 19.1 oz w/ muffler.

Jason

MVVS .49.

18.3 oz, including tuned silencer; for a combo that on cheap 0-5% nitro fuel, spins an 11x6 prop faster than the OS, or TT can spin a 10x6, on 15% nitro. 14,600 RPM.

In fact, it is faster than all the .60 engines in the MAN shootout...

Sorry Sport, i didn't intend that to be interpreted as a slam on Fox. I had a fox controll line engine when i was a kid it was great, but for some reason i haven't seen one since. I'll make it a point to try one sometime.

As for Hobbsy, yes, generally he does know a lot about what he is talking about, i wrote what i did because there are occasions when folks need to be reminded that the rest of us aren't dumb either.

I just wonder how many people would chose TT, Magnum, TSI, GMS, Tower, MDS, or any other OS *clone* if OS was priced the same?

My guess is: NOT MANY... because OS IS better than any of the above mentioned engines. But, because OS costs around $30-$40 more, many people will buy the cheaper alternative and then rationalize their decision by claiming their engine is actually better than the OS...
