Status: offline 		I want a power upgrade for a pattern plane. I currently have an old YS 1.20NC and was looking at a YS 1.40 Sport.

I realize the 1.60/1.70DZ engines are the very best out there in terms of power.

However, is the OS 200fs a valid replacement for the 1.40 sport?

I think the OS will give me the capability to swing huge props (15x12 3-blade, 18x10 - 20x8, etc) on slightly less expensive fuel (15%) for similar power to the 1.40 on 30%, weighs about the same or less, and also costs a bit less than the 1.40. Maintenance on the OS should be minimal, similar to the .91 and 1.20 Surpass. I would like a simple, light, powerful plug-and-play system.

Any comments?

Thanks!

Brett

17X12 or 18.1X10 prop on 15 to 20 percent nitro. Definitely adequate through Masters.

Status: offline 		not too fast, I like the 4-strokes a lot. YS in Europe is not much of an option. Expensive to run on 30% nitro and unless you have people around that understand them, they can be a nightmare.

It would be nice to see an alternative. Unfortunately Saito does not offer yet anything. I would be interested to hear about experience with the FS in pattern.

Joe, thanks for the info. I had a big response typed up and the computer froze.

That 1.40rx is definitely a great engine. I love the performance of the big OS 2-strokes on 5% - 15%. I had a 1.60 with mixed results due to the Pitts muffler (deadsticks), but it handled very well. I especially loved the 12+ minute flights on 14 oz of fuel. I could probably get a NIB 1.60fx, bearing, pump, pipe, header for about $500 or so.

The 1.40RX is an excellent option too. It has two problems though. It requires that I purchase a full-length pipe ($160 - $275) and it requires that I install said pipe (long pipe tunnel). I see the engines for sale from time to time used, but buying new will cost as much as a 1.70DZ.

On a side note, I am interested to see if OS follows suit and releases a big AX series engine (1.80AX? 200AX?)

My plane has a short pipe tunnel for the short 4-stroke pipe. I want a relatively plug-and-play option. I know the 2-strokes will blow it away on power, but power is adequate and it is easy to live with and costs $399.

It's funny more times than not you get what you pay for.

In my field, a good friend purchased the 200 and is a wonderful engine!!!!

Power wise, is about the same as the YS sport, as he told me.

Grate engine!!!!

Robbidos,

I don't understand what you are saying. The OS weighs 1.5 oz more with the stock mufflers, and a little more than an ounce more (40 g) than the YS without mufflers. The OS costs less than the YS too. Reports I have read place the power in the same ballpark as the YS 1.40 sport, but on 15% instead of 30% fuel, with the added capability of swinging a much larger prop more like the 1.60fx. The OS 4-strokes I have owned


Chuck, it is my understanding the 200FI is "supercharged" similar to the YS. Too bad they don't make a carburetted version with the pump and supercharging.

Status: offline 		I've never heard the example of using 200fs to F3A. But I recently hear that a few pilots began to use the new 200fs-p for F3A in Japan. As you know this type has much power(5% plus) than normal 200fs. However I am not certain if this choice is appropriate or not.

Best regards

Srashina

Status: offline 		Srashina, I expect the pump version (200fs-p) will be available in the US soon. It is good to know it has more power than the standard version, thank you for your input!

Actually, it weighs 3.5oz heavier (31.75oz vs 35.27oz, neither with the muffler) than the 140sport and costs 3 times as much ($429 vs $1299) as the 140 sport. It is 1.5oz heavier than the 170DZ and it is only $690. Why on earth would anyone use it if that is all it can put out power wise?

Status: offline 		You are looking at the fuel injected model ($1200). I refer to the carburetted version ($399), here: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPRL4&P=0 . The pump version should be about $60 more and weigh a little under an ounce heavier. The 200fs weighs 32.8 oz and the 1.40 sport weighs 31.75 oz.

As far as power, the 200fs-FI version is supercharged similar to the YS engines and is supposed to be very powerful, although very expensive. I agree I would not use that engine.
