It's the fuel you need the 30% I think . You changed 3 things at once that all help preformance. I start with Fuel easiest too. 129c thats like 264 F you need to RICHEN it up ALOT ... or Change fuel and retune i dont want to be over 220f at 2200HS ..

I"m using the 20% Cy with an A5 and .04 shim swinging 620 SWE blades on 8.8 ratio with the outrage 56/57 pipe.

I have plenty of power. I'm using a 60K 3 needle carb. head at 2000-2100. It might be lower I'm guessing here. I just run it till it feels good. Try lower first then come up with head speed to find your sweet spot.

Git corrert me if i'm wrong but your running a Trex 600n? It's has 8.5 ratio so 2100HS x 8.5 = 17850 ,Now Bigwolf1 is running 2100HS x 8.8 ratio = 18480 rpm. The Nova peak torque is at 18500 ..So at 18500 divided 8.5= 2176HS..see where i'm going ... I think you should bring up the Headspeed.I like to run 200-300rpm over that to bog into as just doing big loops will drop your headspeed 100-200rpm, and tic toc even more..
I know 3 guys running nova's all at 215-230 F or 101c -110c..Nova recommends 212f-248f.. I can't comment on your fuel as i never heard of it till you posted it... 30% is going to run cool be easier to tune and make more power...No saying the 20% your using is bad but your lagging in power you when from 30% to 20% , Lower compression, pipe that's said to not make as much peak power.

What your pitch setting and blades are you using?

my idle1 is 1950 n idle2 is 2100.. tried already 2150, 2176 n even 2200.. 2100 just pulls better..

im using 12 deg pitch with edge fbl blades.. btw i did an experiment yesterday.. tried on hatori fs 3d2 from my 90.. top end is good but mid was really horrible n lots of overspeeding.. haha..

im gonna switch back to 0.4mm n outrage 56 pipe n see the effect.

Theres just no need to scream the butt of the NR57 when using the outrage 56/57 pipe. It makes way more torque lower down allowing lower headspeeds. Different pipes change the response from the motor.

Running 620's at 1950/2100 and it shifts way more air than 600's turning at 2150 this is on 2 x 600N's. (8.5 Ratio)

The 600 blades just dont load the motor enough unless you rev very highly indeed but that makes it for a fussy tune.

If you use the NR tuned muffler even letting the headspeed rip is not a patch on the Outrage pipe as its peaky in comparision and drops out of the power easier and recovery is slower.

Running the same combo's on a Outrage 50N ..8.6 ratio or better still the 8.8 ratio if using NR's own muffler 2100/2150 is enough.

Switching to the Outrage muffler on the Outrage 50N and again 620's and the increase in torque/thrust is a joy as the bigger blades improve drive through manouvres.

You see, It all comes down to how much main blade tipspeed you require to eliminate cavatation in sharp stops. I think you are chasing for something you are not going to find.

The best engines are YS or OS
The Novarossi one is a powerful engine for 2 days of competiton, it burns easily.

novarossi has been the brand with more competitions won in the rc car racing arena where engines rev over 40,000 pm. 1/8 and 1/10 (.21 and .12) engines last for an entire competition season. I do not know how long my .57 will last but I do not, in principle, buy that thing about NR being worse than OS or YS.

Ditto on that Lightningrc..2 x 57's plus my mate has another 2 that have used a fair amount of fuel aswell. Defo agree on adding the shims.

Gernejr this is me running the 57/Outrage pipe Combo at 1950 on the 620's (Maniacs) This is 20% nitro to show you dont have to rev the motor that hard for it to make good power. This is the std 10mm carb

Barney Nice flying. I'm not saying 57 doesn't make torque at lower rpm. I was stating peak torque is at 18500. Git changed 3 things at once and wasn't happy with power. I prefer to run at or just above peak torque myself. Differnet setups need differnet tuning. I prefer 30% as it easier to tune , runs cooler, makes better power. I run two heli's and only want to use 1 fuel. Beside the Nova 57 being higher quaitly motor then others it is more tunable for differnet fuels. I love my Ported OS 50 till i put the 57 in but hated the Nova carb. I had the 60B carb but more work to tune so i reworked a 60L that i'm very happy with. It's also 27gram ligther than 60B. One of the things i love about this hobby is you don't have to do it like the next guy.

By the way "man you fly in some beautiful county... Now that's a background... All i get is trees,grass and flat lands...

Hi guy I am luca of Novarossi
Please listem my advise, if your engine with the high speed needle set correctly for the power you need, BUT you feel over heating, just open a bit the idle needle, becasue she manage also the medium rpm setting. Using RPM governor in 3 d fly the carb open fully and than come back at meedle status very quickly, than you need have a good/ lean set in the max speed to get power, but have the medium / idle preatty ritch to cool down the engine when barrel will moove for quick periods to the medium position.
Use colder plugs.
The "secret" is only in wath I explain you upper, one discoverty that you will SUPER suprised to discovery how easy can be setted your carb, abd using the stock carb you will discovery more power that using the OS one, with colder engine.
In any case Novarossi can and he like run little Hotter forever compared OS e YS.
Rex engine coupling have spamlife of 40 Hour at max stress = 240 fly, I invite any other engine to do the same.
PS if after open the idle to ritch the middle you feel the idle ritch just open a bit the trim trottle
Any question ar welcome.

One great thing about the NR57; it can really take the heat and keep on working.
Yeah right

I 'played' with my N57 for 3 months and just got fed up with all of the messing about. Still can't get all the parts in the UK

I replaced my N57 with an OS55 some time ago and Hey Presto - I haven't looked back. There is no noticeable difference in power and I get both 'ease of use' and great service

OS 55 HZ = Lots of hassle free airtime

3D?? No - just another input error!!!

Thanks ININVENO I changed out the all o-rings and drop 25 degree in temp... can we say "sucking air" Today with the OS carb 2200HS 2 clicks leaner i have 210 degrees rediclous power.. I changed carbs has mine had the 8mm nova carb and after some mods to the OS60L I'm very happy with the motor .. I must say mine idle better than my friends ver. 2 57 with 10mm carb, power is the same.

I disagree that the stock carb makes more power tan 60K which is the one I am using currently. I invite you to try.
And, of course, easier to adjust.
Also Nova engine with Rex pipe at the same OS55 (with funtech Pipe) temp makes more power, period.
To me there is no reason why this engine should go over the 90c to 100c range, it makes more than good power compared with other engines. In my looongggg experience with rc cars I also did not have them going over the same range. Too much discussion about such a simple matter.

Sorry Boys but the OS 55 will not compete against the 57 in hard 3d, I tried hard to squeeze all the power out of my 55 which different pipes and was still not happy.

My 2 rex's are not set perfect at all rpms , but in hard 3D she is an animal , so much more torque than the 55.

If your just flying around doing light 3d then the 55 is for you , people say about the 57 being hard to tune thats nonsence , I set mine along time ago and have only had to click the needles one or 2 clicks ethier way right through winter.

Every one that tested in SAME Heli all 50 size class engine available say the same, 57 powerhouse. And life closer to unbelievable.

In particular one pilot everyone know:
Tareq Alsaadi
He was contact to me long time ago, we sent to him some engine just for test.
After some (100 and more fly) he contact me and he was ready to pay for the Novarossi... now is our pilot for sure...
About tune setting i repeat again, when you set correctly the low speed needles that manage idle and middle, than you just need play around 3 click in the max depending of your weather fly condition. People that has now understood the principle say that is MUCH easier that OS.

Hi Luca,

You're absolutely right. I have my 57 more than 80 flights, it's still running strong. I love it......

If this is a OS50, I have to replace the rear bearing and the piston ring already....

By the way... where are the missing videos???????????

I have an OS55 HZ with over 100 flights and the bearings and ring are fine

A flying buddy has a Hyper with about the same and also has no issues

At least when new parts are needed I can get them without any hassle
By the way... where are the missing videos???????????
Let's hope they're not with the parts shipment - you'll never see them

3D?? No - just another input error!!!
