Yes, i can see there are five bolt head where the bolts are bolted on cylinder head.:)

RE: O.S. 95 AX !!!
 

Well, this IS the "Age of Aquarius", after all. <G>

I see that the Japanese Indigo Children have finally assumed power at OS Engines. <G>

RE: O.S. 95 AX !!!
 

I like it. I wish it was ABL as I've had very good luck with the two AX .75's I have.

RE: O.S. 95 AX !!!
 

It looks like a scaled down 1.20AX

Nice to see a angled needle assy.on the carb and a head with more than four bolts. Should be a winner.

RE: O.S. 95 AX !!!
 

Good Find.</p>

I'vebeen speculating whether OS would ever release an engine midway between the .75 and 1.20AX. I even asked Bax a couple of years ago but he didn't know at the time.</p>


The .95AX looks to be the same weight with very similar bore &amp; stroke to my Webra .91 P-5 which is a brute.

I have a few models where a regular .91 is a tad weak but the 1.20 is overkill. I've been using the Webra .91 for these but the .95AX might fill that void for me.</p>

I wonder whats next to get the AX treatment?</p>

AnAX somewhere between 1.60 and 1.80 would be good, please OS.</p>

RE: O.S. 95 AX !!!
 

This engine doesn't do me any good, except give me hope that something in a 1.40 to 1.50 four stroke might be in the works. They're still lacking in the 4-stroke performance world.

I hope everyone the 95AX makes a lot of people happy. I like the AX engines. And I like the ring on my 120AX.

RE: O.S. 95 AX !!!
 

our importer "model engines" has the ax95 in stock now and they say it is designed to turn bigger proppellors than the fx91 i will check lhs for price on monday and maybe pick one up and start the testing next week. http://www.modelengines.com.au/libra...02009%20v2.pdf

Just wait untill Great Plaines releases there price for it.[X(]

RE: O.S. 95 AX !!!
 

Hi Greg,

If you get one i'd love to here how well it does with a 14x8 and 15x8 props.

For comparison, my Webra .91 does 10,000 and 9,300 with just 5% nitro. It's a beautifully made engine but expensive. I'm hoping the .95AX performs as well as the webra.

RE: O.S. 95 AX !!!
 

not a problem, ill start a thread in the tach forum if the price is reasonable and i get one, i will also do some comparisons with my fx91 on 12x8 14x6 13x8 13x9 12x9 apc and i have some 3blade ma props as well.

They have. All you have to do is look at Tower. $279. Thats the same price I just paid for my 1.60FX. Minus $60 for my club membership when I when I purchased $21 more with it. :D

RE: O.S. 95 AX !!!
 

GP is crazy to think people will pay that much for a .95.[X(] There pricing has steered me way clear of any engine they make currently.;) In the mean time I have found engines such as the Tower .75 that will perform right with the .75AX for 1/2 the price, and you do not have to worry about the cylinder peeling in the mean time and if any parts are ever needed they will not break the bank.;)

RE: O.S. 95 AX !!!
 

The webra P5 is also about that much. Prices are significantly higher for comparable fourstroke engines and people have no problem buying those? The 95AX should be a good engine like the rest of that line.

RE: O.S. 95 AX !!!
 

You cannot compare the price of a simple 2 stroke engine to a complicated fourstroke. I would and have paid more than this selling price for a YS 1.10, but to pay that much for an engine when others close in Displacement are half the price is stupid.

RE: O.S. 95 AX !!!
 

OS pricing has nothing to do with logic or real world costs. The old axiom of, "charge what the market will bear" is at play here. I only wish I had a product to sell that had such a great reputation and following that would allow me to charge ridiculous prices for it - and get it.

It is disgusting, yet we are fortunate in that we can often buy two or three econo priced two-stroke engines for the price of one popular OS two-stroke engine. Furthermore, folks that could only afford an OS two-stroke engine before, can now venture into buying newer, lighter four-stroke engines, such as the new Thunder Tiger .75 four-stroke engine, etc.

RE: O.S. 95 AX !!!
 

I don't totally see the point of that engine.
I have the .91FX, in a .91 acrobact... it's not the most powerful motor out there but least it's small and light. So a new version hardly seems to solve the power hunger.
I was thinking about the 1.20AX (and heard a couple of negatives) so'I've decided to replace it FX with a 1.20FZ I had laying around. The 91fx going into a decent .50/60 sized acrobat where I think it'll be more suited.
Point is, OS are coming up with a couple of new (high techi') engines in the .90-1.20 range. Why the h#ll they didn't just keep the old 1.08 and been done with it?
I had that in a 1.20 CG extra and it was FANTASTIC! A real mans engine, globs of low end grunt... Felt like a 4 stroke!
Which is about a much as anyone could hope for.

RE: O.S. 95 AX !!!
 

I agree, the 1.08 is a fantastic engine.

RE: O.S. 95 AX !!!
 

David Bathe said, "Why the h#ll they didn't just keep the old 1.08 and been done with it?"

Because the 'sheeple' need something shiny and new to flock to.

RE: O.S. 95 AX !!!
 

But 1.08 i heavier than 91fx 95ax and almost the same as 120ax??

RE: O.S. 95 AX !!!
 

Guess so... the .91FX is basically a drilled out .60... which is neat... if your .60 lacked some and you needed a little extra pep.
But that ol' 1.08. It had serious balls in the old school manner. So much torque... as stated... it felt like a 4 stroke.
The 91FX hasn't any... whimpy IMO. The new 1.20 basically delivering what one expected from the .91. High tech, flashy a great cosmetic design... but no BEEF. No brute force.
You need engine that delivery the milk at low rpms and at low throttle setting, thats why we love 4 strokes... and covet the simplicity and delivery of the 1.08.
Old fashioned, simple low tech long stroke. It's very hard to beat.

RE: O.S. 95 AX !!!
 

Ill wait untill the price comes down a bit before buying. $359au is a bit to much for now. Greg

RE: O.S. 95 AX !!!
 

So for example the magnum 108 is the same?

RE: O.S. 95 AX !!!
 

Is Sanye still making the 1.08? I've been trying to buy one at the seriously discounted price that they were selling for, for a year or two now. Everyone is always out of stock and then they suggest that I buy the much more expensive 1.20 (compared to the steeply discounted Sanye 1.08 - which no one stocks), which is not what I wanted. I have nothing against the Sanye 1.20. It's just not at the price point at which I was willing to buy.

I do not know how the Sanye 1.08 compares to the OS 1.08 power and tractability wise. I know that the Sanye (Magnum in my case) .91 is a reasonable competitor to the OS .91FX from which it was copied. Anyone?


Ed Cregger

RE: O.S. 95 AX !!!
 

I have allways understood that the Sanye 1.08 was more of a low RPM Torquey engine, and does not like to rev like the OS 1.08 did.;)

RE: O.S. 95 AX !!!
 

Here you go Ed;) http://www.hobbycity.com/hobbycity/s...e_Glow_Engine_

Very very cheap and I suspect it is every bit as good as the original, I have not tried this particular size but I have had great luck with everything from .30 to 180 from ASP

Hobbycity is a great web shop, I have personally ordered from them 54 times and all have been great, higly recommended:D

RE: O.S. 95 AX !!!
 

Yep, my ASP 1.08 Redhead was designed to run happily at under 10k rpm. A friend of mine was powering a hotrod version of an RCM Trainer 60 with his OS 1.08 and was using a Mac's tuned pipe to get the rpm up there a bit. The two engines do appear to be tuned oppositely. Thanks for pointing that out. I had forgotten about it.


Ed Cregger

RE: O.S. 95 AX !!!
 

So is it the same engine?? The os and the ASP 1.08??

RE: O.S. 95 AX !!!
 

I am surprised at that......
Does it run as reliable as a OS engine/??

Reading a old issue of MAn (I not sure) but they said that the 75AX had the power band of a 4-stroke???
Any truth to this???

RE: O.S. 95 AX !!!
 

No, they are markedly different in how they are tuned. Still, each performs well when propped properly.


Ed Cregger

RE: O.S. 95 AX !!!
 

I can('t?) believe they have the nerve to charge more for the .95 than they do for the 1.20. How does that make any sense?

RE: O.S. 95 AX !!!
 

Just don`t buy it:) If no-one does, the price will quicly come down;)

What I would like to know is if it is any more powerful than the 91 fx and if it is less weight? It is too rediciously priced for me to think about finding out myself:eek: My 91 FX is performing really good in the meantime[8D]

RE: O.S. 95 AX !!!
 

I can not imagine that to be the thruth:eek: When will the fourstrokes scream at 20K like the twostrokes? It is not going to happen, fourstrokes will still be the king in low rpm grunt and acceleration of big props and two strokes will be the king of high rpm on smaller props even though they can be quite reasonable in 3-D planes

RE: O.S. 95 AX !!!
 

anyone tried the 95ax yet?

RE: O.S. 95 AX !!!
 

Like what happened to the OS 35AX:D

RE: O.S. 95 AX !!!
 

My 1.20 has a bit of low end torque, like 2-3000 rpm. Swings a fairly decent prop (16x8, maybe a 15x10 but it's missing the mid-range torque). The small AX engines like high RPM - 12000+. The bigger AX engines are happier in the 8-9000 range. I think this is what they're referring to, and they're really full of them selves when it comes down to it. Nothing compares to a four stroke.

RE: O.S. 95 AX !!!
 

I think the price advertised by towerhobbies or better , the price approved by OS for selling is ridiculous HIGH.

You know i only had OS engines in the past and present i have 3 OS's,

but come on guys...... we don't have a bank in our house to spend money like this...

Just my .02$....


Do you think it will ever drop significantly?

Kostas

RE: O.S. 95 AX !!!
 

What about Honda's 250cc four-cylinder inline motorcycle engine that redlines in every day use at 17k rpm?

If modelers would be willing to pay the cost for overhead cam, four valve per cylinder model engines, I'm sure that they could have redlines much higher than 17k rpm. However, we seem to like our pushrod four-stroke engines to chug along spinning large props. I know that I do. But I would love to have one of those little 250cc four-cylinder Honda motorcycles. I wish they sold them here in the USA.
