I used to only fly OS, and I finally made the jump to YS, started out with the YS 80's and loved them, then I tried out the YS 90ST and loved it even more, then I figured I went as far as YS 90 ST might as well go with the YS90SR.

And let me tell anyone who wants to listen, this SR is one heck of a great motor, I bought it new, and set the needles to the factory required settings to break it in, it fired up like a dream, I couldn't wait to see how she would handle the straight throttle curve break in, hearing about this motor and its power and Im here to tell everyone it was like I had the gov on she just had so much power to weight ratio that the motor didn't even bog out even as I did easy climb outs and just mello forward flight and turns and even when I returned it back to me. WOW.

Anyone not running this motor has to at least try it out, if this is what Im getting just breaking it in, then I cant wait to see the rest of its power.WOW

This hobby sucks, when your not flying.

Definately a fine engine. Very little effort needed to set it up. I did the same by flying initially without the rev-limiter activated on the 7100R and it was still very easy to get it set up to run properly on regular curves.

Give it a gallon, or so, break-in, before you start to lean it out. Then, hang on to your hat. They have amazing power...

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!

and without turning on the gov, I wanted to see how she would handle just a straight throttle curve break in,
FYI You are ALWAYS supposed to break in an engine with the gov off.

Yes the SR is a very good engine. Give it another gallon or two and just feel the power that builds with every tank..

I have always heard this but I am a bit curious, if you dial it in safe why not run the gov, just fly gentle in the beginning and work up to it. Of course if you don't set it up safe then I could see leaving it off

Setting it up safe has nothing to do with it. A gov can mask tuning problems making it more difficult to tune.

It was a figure of speech, as I was excited to see how she would run without gov on, cus I know I cant run it with it on till she breaks in.
I guess I could of worded that better.

Some say gallon some say three to four tanks of fuel before leaning out, I would like to hear from more out their on the right amount of running rich till its ready to lean out.

What say you all????????????????????????????????????????

For me a good man said on the fourth tank start to lean her out.

I start leaning on the second tank, going a click or two. THis way it takes around 6-8 tanks to get it fully dialed in. Thats just a little over a gallon. Then I start hammering it..

I've always been fairly conservative on engine break-in. Call me paranoid, but after I ruined an engine from leaning it too fast.....

Hell... I can fix that.
Uh oh..

This is really bad, as I read some of the post above, I keep staring at my SR fury extreme, ive now cleaned it 3 times thinking of tomorrow and burning more fuel to get it leaned out and seeing the full power potential.

Im getting sick to the stomach thinking of tomorrow Im not going to sleep tonight, on top of all this my buddy is in Las Vegas at the competition and rubbing it in on the great weather

OK OK OK

Burned up two gal's of fuel today switching back and forth between ST Fury Extreme to the SR Fury Extreme both set up the same, but the SR Fury Extreme has 710 RT's and the ST has 690 Radix blades.

Now after I put almost a gal of fuel in the SR to finish breaking it in I lean her out, and when I set gov for 1950 and flipped the switch to idol up one to see the heli's full potential I will have to say besides the 710 kinda slowing it down a little, she does have tork, she has a power range that put a smile on my face ear to ear, all day long, I kept going back and forth and I love the smaller blades on the ST, but a good friend of mine told me that he felt the ST's have a little more snap to them, and he is right, but as for the SR and ST having both is a dream come true.

Now for the big one, it only took me one full tank to dial in this YS SR, and didn't touch it again the rest of the day, left it a little on the rich side.
Now that's a motor................................
I am trully upset with myself over one thing, I was stupid to wait so long to go YS.
