1.8 K? I believe you would be able to buy two 170DZ for that much...

Well Tower price is way high....

I posted one on sale in ebay for $1,199 with hatori exhaust....

http://cgi.ebay.com/ws/eBayISAPI.dll...6197&rd=1&rd=1

Even at this price I could not attract any bid.... I've got 3 sets, one set of this too much, so I guess I'll have to use them all for myself....

Does anyone really buy this stuff at these prices. First they put the 5 cly. up to $2000.00 and now this. I like OS engines but this is crazy [X(][X(][X(]

$1 200 - NOK 7 000.
That's very cheap for us. The 1.40RX-FI costs NOK 10 000 here.
Even adding VAT to your price, it's still under the 1.40... but now out of peoples range.
With some slight price adjusting at your end you could do good business here.
Even though, I believe the engine is just to complex and replacement part to expensive for general use and hope that OS will produce something that fits between it and the sports 200.

Still, NOK 7 000 if you're prepared to do some smuggling and you find me a Norwegian that isn't... it's a bargin.

The non fuel injected OS 200 is priced the same as the Saito 220.

Their fuel injected prices have always been somewhere north of the stratosphere.
I don't get 'it' either but having money doesn't begin to equate to smart-------after all let's not forget the Hilton offspring!

Ahhhhh, springtime in Paris......

Any news on the likely availability of the practical alternative(YS170), to ordinary mortals?
Or,even better, when might it filter through to Hong Kong, or Singapore?

As for the OS 200 FI, the ordinary OS200 with the Hatori exhaust put out power only to the vincinity of a YS140 limited, not even up to the 140 Dingo level... My feeling is that if OS would drop the FI system, and instead put in the supercharge and the direct injection system (aka everything on the backend of the FI engine) on the regular 200, it should become a comparable performance engine to the YS Dingo, also price would not be as high as the current FI. I mentioned this idea to OS people, but they seems not interested....

Back to the OS 200 FI, the problem that I face using this engine now is the engine mount. The back end of the engine is quite bulky, and it does not fit most engine mounts available now. Also, I worry about the longevity of the sensors on the OS200, eventhough now they did away with the exhaust tempreature sensor, but still I wonder whether those tiny sensor/solenoid valve inside the engine could take the vibration of the engine. I did not have much luck with the 140 FI...

YS 170, I had 30 pcs on order long time ago, and after months of waiting finally I have 6 pcs coming hopefully this week... and they have all been spoken for... They are not cheap, YS increased price, and I had to pay premium to my supplier to get them...

iT's really depressing when you say the normal 200 is only puting out what the old L managed.
Mind you, I suppose thats on 15% so I suppose it isn't that bad.
Shame that OS haven't got this organized. Also building such and expensive engine without a dedicated mount. Very strange.

It seems as though OS is way out of touch with or doesn't wish to product target our SIG. I know that we're talking 4 stroke here and making cost / power comparisons, but THE engine , IMO, that would meet our needs and SELL LIKE HOTCAKES would be an OS 160FX with a user friendly integral backplate pump , a few internal mods and a proper carb. I guess the 160FX will morf into a 170 AX or something else in a year or two to appeal to the masses ...but a pure pattern , non-EFI version ?? Unlikely. In the mean time , the 140RX and 160FX w/ Perry or Iron Bay type pumps will satisfy many ,including me.

You see, IMO OS got stung when they pumped so much energy, money and hype into the 1.40RX. Regardless of all the trumpet fanfares, it was somewhat of a dog from day one. Sure the best two banger to date but it never just kinda worked 110%. It's taken many years, slight changes and mucho experimenting by us lot to get it to function 98%. Then out of the blue, OS introduced the1.60FX.
This was proceeded with no fanfares, no hype just kinda turned up in the shop. The problem was that this non special, cheap sports engine perfromed far, far better in an F3A plane than OS's own dedicated F3A engine! Imagine the curesing. Here's something knocked up by a couple of juniors in the sports engine department that completely blew away the big budget and brains department responsible for the 1.40!

Now, there a real chance that history could repeat it's self.
If OS make an normal supercharged motor, it'll produce exactly the same power as the FI yet function, simpler, better, easier... and cost considerably less.
Thats the one we want and we want it to deliver on 15%!!!!!!!!!!!!
Not 20% or 30%....... 15%! No batteries, no electrical leads. No black boxes, no down load to your PC and make Excell sheets out of your engine tempurature data possibilities.
Now somebody give the project to those juniors in the sports engine department.

Funny you should say that----I've got three like that----
2 with a self-modified backplate, and one with a nice(but a bit pricey) purpose-machined Aussie one---& all 3 using old OS pumps---one 140,one RFP61,And one Hanno.
All use the old RFP type 86 carb,with the return to the pump blocked off for simplified plumbing.
And all are shimmed out 35-40 thou...gives a few more revs and softens the sound nicely(does that qualify as "internal mods"?)
They all do 8300-8400 on 15 nitro, on an APC 17/12(so a few more than the YS 160 on 30), and idle easily at 1700-1800(or less if you wish),and transition nicely and consistently once the carb has been set, and a bit of fancy throttle curving has been done.
BUT,in flight, they aren't quiteas easy or forgiving as the YS 160 to use,so,at the top levels, they're not quite there....

Edited to add---and a stainless rear bearing....

Very interesting. I have modified my 160 FX by grinding the exhaust port 1mm higher thereby raising the timing from about 132 deg to 144 deg. Which is still pretty mild for a pipe. I have a type 86 carb I thought I would try. The transfer in the crank is 14mm as compared to 9.5 in the stock carb and 12mm of the type 86. Am using a Perry pump as it hadn't occured to me to use one of my old rf 61 pumps. Any links to back plate mods to fit them in the 160? I will try the head shims, what is the reasoning? Here is a link to my current project which has pics of the linner mods and pipe building. http://www.flyinggiants.com/forums/f...-miro-f3a.html

What does **** equals to? I could not find it in rcu....

Fly!ng G!ants. It's all one word and replace the ! with the letter i. For some reason, people like to censor other websites on RCU.

well have seen the engine and must say ...wow what a nice piece off machine!
well price is a bit high , check this link http://home.online.no/~ofremmi/F3A/T..._fs_200_fi.htm
O. Fremming has flown it in a Oxalys .

OS was pulling this stuff with the Hanno 61 for a price competitive with the YS...guess who made bank?

Well, thank god Ole has some experience to publish.
Been waiting half a year for a the great Jason Sulman to make an effort and report his impressions.
Zip.

Some said no one would buy the 14 Channel Fut-aw-bah radio at $2900 and $2200 but they showed up at the field. This engine will as well. If it doesn't sell well then the price will drop. Don't hold your breath.

Ron Barr has been running this engine for quite a while now, maybe he'll chime in and tell us what he thinks. He's gone to great lengths to test out several different props and has experimented with it to see what setup he likes the best.

I’m sure it is a great engine.. when it is working. I think the main question is if this engine works without having a monthly subscription of the electric fuel nozzles from OS (as one would need to keep the 140FI running). I think the silence, so far, from the sponsored pilots is hinting something.
