Have run mine on Sig 30% heli fuel since day one.Idles and runs perfect right from the get go.Running an APC 15x4 wide blade.Spool up is quick and only on the 8th tank.Haven't tached it yet.An Excellent motor.

Hi,
I also have a Saito100.
This engine is mounted on my Extra from Graupner.

But my Question is; what is a good prop for this setup?
I know it isn't a 3D plane but i want to fly it in 3D style.

What are your recommandations?

I am getting 10,120 max out of an APC 15x4W running on 15%/18 oil CoolPower.

This isn't even broke in yet. How's that for an RPM on a non broken in engine, good or bad?

With a APC 15x6 I was getting 9,750 out of the same fuel and everything? Is this good? Still on the non-broken in engine. I am running 1/2 turn from peak out where I fly at.

Thanks

~Michael~

I've got almost 1 gallon of coolpower 30% through my Saito 100 spinning a 16-4W apc at 9400 rpm. I have'nt adjusted the low speed needle yet but I plan on it the next time I take it out. Any tips here? I'm sure it's rich from the factory.
Thanks to all.

Well I made the needed adjustments on the low end and I'm turning my 16-4W at 9400 RPM. Runs great but I did have it die in the aie once and had to retune it. I think it's better now.

What are you guys getting for idle speeds? Particuarly those with 14X8 props... Thanks!

How are you liking that Slimline Pitts? I have one (the inverted design) for my 1.00 and can't wait to put it on a stand and try it. I hope I can pull those same RPM numbers.

RVM

Saito 1.00
Stock muffler
25% Omega
About 3/4 of a gallon through it; still breaking in.
Pretty much sea level.

All numbers are peak values
APC 15x6 : 9900
Xoar Laminated Wood : 9200

The Xoar felt like it pulled a lot harder (was tuning my engine on the plane and making sure everything was set up properly before flying) than the APC despite having significantly fewer RPMs. I might be able to get a few more out of it when I have a bit more time to fiddle with the needles. I think the engine still has awhile to go for full break in.

Anyone have a link to a site that explains in detail how to properly tune my Saito 100 GK ?
I can't seem to get a consistent idle.

Thanks;

Look in Glow Engines. The sticky labeled Saito Notes will have the info you need.

This is after about 45 minutes break-in and tuning low end needle
It vibrates like crazy at mid rpm and that's with a well-balaned prop and Tru-Turn 4" spinner - torque pulses??? (my first Saito - so I'm no expert tuner on this one)

Saito 100, opened the box today, put it on bench, fueled it up;

Cool Power - Pro Pattern 20
APC 15x6 prop

after a very brief break-in (~20 mins)

with a still very rich setting (not peak) i tached 9700 RPM.
with a still rich LSN, 2100RPM consistent idle.

love this machine..

I am pretty impressed with this engine so far especially after some of the comments I read on it being a shaker (not!). The Turboheader muffler is also a winner. Adding the 90 degree header and exhaust extension shows basically no difference in the readings as far as I am concerned. The rpm with just the adapter went back and forth between 9,720-9,50 like a slow clock but with the exhaust extension added on stayed at 9,750 with an occasional dip to 9,720, which was interesting to watch. I would not say one is better than the other given the small variation and the fact the engine is still new.

84 Degrees
56% Relative humidity
Approximately 425 FT ASL
Omega 15% 4S fuel with nothing added
All figures on APC 14x8
I finished up the first gallon as I took the last set of numbers including the idle.

9,510 with stock muffler
9,750 with TurboHeader Muffler (briefly touched 9,780) (pretty much as expected)
9,720-50 with Saito 90 degree header and Turboheader Muffler
9,750 with Saito 90 degree header, Turboheader muffler, and unmodified Hobbico exhaust extension (not what I was expecting)

As for the idle, well I had a real nice idle that I played around with to see how low it would go while staying reliable. I didn't play with the idle until the end with the Turboheader muffler on it. I decided to just show a picture instead (1,560 with the engine warmed up). I got that same idle figure on two different runs so I should have no trouble holding an idle of 1,800 or so. The stock idle needle setting was waaaaayyy too rich but that wasn't a surprise and she smoothed out a lot after it was set correctly. The new PSP test stand is a winner too. The old one just collected some exhaust so time to retire it.

The Turboheader muffler also has a nice sound throaty sound to it and adding the extension just changed the note a little more. I am happy This engine is going into a H9 P-40. The 100 idles really nice. That impressed me quite a bit as did the Turboheader. The muffler arrived two days after I ordered it so the service is great too.

Hi everyone!

Just bought a slightly used saito 100, and is wondering if anyone run their´s with a 16" prop? I have master airscrew and APC 14x6 and have ordered zinger 15x6 and 16x5. Will it swing the 16x5?

I want to use as big prop as possible without hurting the engine, because it will look more scale on the H9 .60 corsair it´s going in.


Thanks,
Lars.

Lars,

The 16 is alot of prop for the 1.00. I run a 14x8 APC on my Corsair and get good performance. Shoot for an rpm in the mid to low 9's and your engine will be happy.

saito 100 swings a APC 15x6 over 9600 easy with 10%nitro. With 20%, over 9800.

YBP

Ok, thanks for the quick answer.

Won´t test the 16" until I get my tach.meter.

Hoping the 15x6 atleast will turn some descent #´s.

Thanks,
Lars.

liquid_TR:
I have 15% fuel and with that # on 10% and 15x6, the 16x5 looks to be within reach.


Thanks,
Lars.
