Default OS 81FS-a

Has anyone run the new OS 81 yet.. I have read a couple rumors that it will be as strong as the OS 91..Being fairly new to OS four strokes what do you guys think?....I need a 91 size engine and would sure like to run the new 81 and not have the mess.

I have not seen one run. I went to Tower to look at them. It is $100 more than a Saito 82. I don't think you will see a lot of them around. Not saying anything bad about the engine. It may very well be a light weight powerhouse. It's just to high.

If I needed a .91 size 4 stroke I'd get a Saito 100. The OS 81FS is a little high in price at $350.00 compated to a Saito 100 at $280.00 thats about the same weight. Use the $70.00 you'll save and buy a couple servos.

The mess can be avoided with the Magnum 91 RFS as well, it has a return tube from the crank case to the intake. It also produces as much power as a normal OS 91. That being said, the OS/Magnum 91s are not the most powerful engines out there. I also have an OS 70 Surpass II (why they would discontinue such a superb engine I will never understand) which pulls just shy of the OS/Magnum 91. I use 14x6s on all of them and the 70 is just a few hundred RPM shy of the 91s.

To me it doesn't really matter how wonderful the new 81 is. It replaces the 70 Surpass, a $210 engine with a price tag of $350. That's a 40% price increase. I suffer from growing family syndrome at this point in my life...so I do this hobby as close to on a budget as I can. That being said, I love my OS 70 Surpass II, I want to marry it and have children with it (don't tell my wife). I can handle it being replaced with a better engine, I can handle the price being higher to start with but 40% is too much. I'll buy the Magnum, save money and be happy.

Chief Aircraft shows:

Saito .82 shipped- $254.95
Saito 100 shipped- $279.95
Saito 1.25 shipped- $339.95

They aren't carrying the OS .81FS yet, but I would expect them to have very good prices when they list it.

I love my OS engines....mostly old FSR's and a lone (old style) .90 FS.
I can't see spending $350.00 on an .81, when I can buy two .91's and
three gallons of fuel for that money. Sorry, OS high prices left me
behind a long time ago, not to mention the parts prices.

Perhaps it's unkind to put a damper on someones inclinations.... but I
see these prices as taking unfair advantage of hobbyist's and modelers.

Think about it....you could buy three lawn mowers for that money. []
That would be three 4 HP Briggs and Stratton engines.

Gimme a break, OS. [:@]

Default RE: OS 81FS-a

Seriously Dave, I'm right there with you...

I've got a mostly Magnums and OLD OS engines. I have 2 Old FS-61s, a Pre-Suprass FS-120 and then a few SF series 2 strokes. The only new OS is that 70 which as I said I want to have children with...

The price tag of OS engines is too high, I'm sure the market will prove this...

Before I bought one single OS 81 I would be more likely to buy as has been suggested a Saito (I have none) or a YS TWO magnums 70s.

the price of the FS-200 dropped 50.00 after about 2 months, I am hopeing the 81 will drop soon and get signed on the good ol' 3pay thing at Tower.

Well put but everyone. The OS is just to overpriced to even think about it. It is allmost as expensive as a Saito 1.50 or 1.80. Heck, it is as expensive as a YS 1.10S that would out power it 2-1. Yikes, another OS rip off. Buy the Magnum .91RFS, you will not disaspointed with it. We bought a hole mess of them last year for $119.00 shipped to our doors last winter when they were on sale for $149.00 with a tower $30.00 discount code.

Couldnt put it better myself - Its a ripoff @ 350$. And as Asmund said, you guys in the states are getting your engines at VERY low prices compared to europe.

Its us that are most affected by these huge price tags. Ive to order my engines to my friends in the states every now and then, so they could bring them back on holidays and such..

Id only be able to buy it if the base price goes down by 50$, then tower would knock down another 40$..

I love the quality and out of the box experience on OS engines, (and always loved it) I love the parts availability, but frankly I hate the new price tags. And there seems we can do nothing about it.
The best person to answer to why its so expensive would probably be the representative of OS engines mfg.

GP (Tower) will never lower the price unless the sales are low, and as long as some people who have little clue as to the actual value of the engine continue to buy it, it just feeds the fire.

Wow, I guess no one has run or seen one run..I had asked if anyone knew if it might compare to a .91..Not likely i guess as it is smaller.Instead all i get is the usual moanin' n groanin' about cost

Don't really care what it costs or the alternatives and yes i will be one that fuels the fire...After all it is a hobby and one can and should be able to choose what items and how much he wants to spend instead of being critisized

Wingburner,
What did you expect. The engine is priced about $100 over other comparable engines. It is also less powerfull and $100.00 more than there own .91.[sm=idea.gif] Which has a very good reputation for running and durability even though it is somewhat heavy and not the strongest on the block in the power department.

Yes it compares to a 91, weight wise. The 81 is 615 grams and my 91 is 640 grams, a little under one oz difference. Why bother with the 81 after all???

The 81 uses the piston/sleeve & cam from the 91

Sorry Wingburner. I started this mess. Part of point should have been: It is going to be hard to compare one because most wont buy one. I live in a small town so you guys will see more new stuff than I will. I have yet to see the OS 70 Ultimate run. It's been out like 3 years now.

My question i thought was simple...I didn't ask for engine or price comparisons from other brands..I asked if it would be close to the OS 91 in power..I have read where the new 56a is very close in power to the 70 and just wondering if the same might apply to the 81 vs 91...That's all...As far as being out of my mind for paying 350 for it...I doubt it, because if any of you think you're getting value for the items you buy, time to wake up..It's a hobby and it's all over priced, but unfortuneately that's what hobbies usually are, overpriced enjoyment..I might stress the enjoyment factor

Now if someone has some info on the OS 81a vs. the OS 91 comparison i'd like to hear it, other than that keep the other brand and price comparisons out of it plz.Not interested
