It shouldn't take more than 1gallon to properly break in the motor. Its not gallons or flights or time that breaks in the motor, its heat. The ring will not seat if temp is not brought up high enough for the ring to seat in. This is per Mr. nitro himself, Tim Jones. My ys91srx was completely tuned and running at top speed in under a gallon. Runs like a champ 3 gallons later. I recently changed pipes and was able to see the piston and it looks great.

3 gallons is from first start to 100% tip top condition to fly. Break-in engine does not mean until it starts smoothing out only....

I am not going to spend $500 on a motor then another $90(3gallons) to break it in.

Ya'll can forget that, 2.5 turns on both, 2 tanks normal mode hover, 1 tank stunt one very mild 3d flight, all other flights on 1.7 turns in on both banging 3D while tuning. I have neither the time nor funds for long run ins.

Hovering does not alone seat the ring, it takes full throttle to get maximum pressure behind the ring to seat in the ring with the engine at operating temp. Better to go fly do loops let the engine load up on the entry and cool on the exit. The break in is almost done when the oil can breach the crosshatch, that happens fast, remember the piston is making around three hundred stokes a second. That's around a million times a gallon do you really think it takes that many revolutions to break in. The engine will need to be tuned for the load you exert on it while adjusting the needle.

No one actually say that 3 gallons were used for hovering only.......

Was making reference to taking three gallons to break in not hovering for three gallons.

The ring has to wear to match the linner,i dont think 1 gallon in a 90 or 120 will fully wear the ring. running overly rich will just slow down the process.Dodger is right to load it flying like he suggested,i do this and slowly sneak up on the right fuel mixture. Ring seat is critical in YS engines because blowby on the ring can cause erratic mixture settings.Part of the break in process is heat cycling to stabilize the internal components.

At DS8717: that is what I normally use the 3 gallons for....it might sound excessive...but I have run through this process for 6 engines and the oldest of them is about 1.5years old....and they still run fine and still makes very good power...

Thats the way i do it,the engine is not fully broken in on 1 gallon of fuel,at least 90 or 120 size anyway. OS engines seem to break in faster than YS from my experience,they seem to run smoother from the begining.

Hi Everyone,

Finally got a chance to spend a full day with the YS120SRX, and I'm extremely impressed!

1 - it holds it's tune
2 - it's smooth, they have fixed the vibes
3 - has loads of power!

I ran Rotor Rage 30% and it became clear after a number of tanks that the second shim wasn't needed at my elevation with 30% and the OS8, I flew with it today anyway, but will only improve in power. I'm still getting the finer running down, but is friendly on the needles compared to the YS120SR. I had it a tad lean on idle and mid but easy fixed.

I backed the gain on the VBar give off from 60 to 40 and that got rid of a bit of hunting on the tail in idle up, heli is now smooth in idle up. I couldn't hover in idle up smoothly with the ys120sr, the change is reflected in the Vbar and current draw drop.

Here is a quick couple of videos, will get some better ones soon (I hadn't flown it since last November )

Nice flights Brendan, the G4's are awesome birds too, thanks for sharing.

It sounded good through out the flights, but I would be scared to poop knowing I may not get spares. What elevation are you flying, is it negative sea level?

Thanks buddy, I'll get the exact elevation, but it's not far from the ocean and you don't drive up any hills or escarpments. The engine comes with one shim installed and it must be ok for 30% stock. Not too worried about spares, the bearings are common, so would be the usual piston/ring/liner and I bought the engine from RCJapan who had fast shipping.

I just tried 20% up from 15%, 15 was plenty almost like electric. With 20% holy ****! On the deck work is back in effect.

Cant tell the difference between my electric now, tic tocs are very fast, heli is very strong. I would have to run either a YGE gov at 2000hs or 2150-2300 on a castle to get this bog free performance.

Looks like a very strong engine.....what is your current needle setting....assuming that it is only on the first couple of flights...?

Hi Eagleman, those flights were after about 10 tanks, I just reset the needles tonight as I dropped a shim out, but from memory it was 1.75 on mid and about 1.25 on high. I quickly checked it before resetting the needles to 2 turns each for the reduction to 1 shim. Will see where they land at with one shim and a few more tanks. Hopefully get some more time soon to play with it as it was a load of fun to fly it

Classic! Haven't seen him in ages, he used to come across for a fly with Kevin at SSSFA, great pilot and nice guy. Let me know what you think of the engine when you get it.

Could you tell any difference in the way the motor ran after 10 flights,was it smoother,more power.....

The engine was getting smoother each flight, with the needles slowly coming in. I don't think those needle settings of mine will be the final settings. You can tell YS did a good job balancing this engine
