Satio 125
Ok, I had the time today to run the motor. Over all I'm pretty Impressed with the 125 so far. A few things came up that I noticed. At full throttle the high speed needle would turn from the vibration. I spent quite some time balancing the props, so I know they are good. The other thing is I could not get it to start by hand. On all most every motor I have, I start by hand. I'm not sure if its because its not completely broke-in or what. The motor would run backward when ever I tried it by hand. Be sides that, this seems to be an awesome running motor. Even at rich settings, very responsive.
Here are that results:
Arvada, Colorado
Altitude: 5407
55°F
31% Humidity
Coolpower 30%Heli
11oz. Fuel tank
O.S F plug
Four tanks of run-in, before leaning it out for the teats.
Run #1
APC 15x6 9700rpm @ 211°F
APC 16x6 9000rpm @ 223°F
APC 16x4w 9300rpm @ 215°F
Run #2
APC 15x6 9800rpm @ 215°F
APC 16x6 8900rpm @ 195°F
APC 16x4w 9800rpm@ 225°F
@ Idle was running about 100 - 105°F
Idle was @ about 1700rpm with awesome throttle transition.
With mild runs it got 12 minutes on the 5th tank, and 13 minutes on the 6th.
High needle: 2 1/2 turns out
Low needle: factory

Dark,
Did you try "bouncing the prop" backwards off compression? This is the normal start procedure for the Saito. Mine starts so easy it is a joke. RPM numbers match yours.

RE: Satio 125
Me too, if I try to start it fowards it will run backwards but if I start them by flicking it backwards of the backend of the compression stroke they run correctly.
I have more problems getting my .91 to start versus the 1.20 so I wonder if you're having the same problem I am which is that I must prime the 91 5 turns more than the 1.20 to start it.
Thanks for the numbers, I'll be getting one soon for my winter build.

My OS 1.08 turns those numbers with those props. I thought the 125 would do a little better than that. I actually get closer to 11k on the 15-6, but I like the pull of the 16-6 better.

Deanos,
Don't forget he is running at 5,400 feet altitude. You would get much more power in VA running the same 30% fuel. And (if the 125 is similar to my 100's) it isn't even close to broken in yet if you assume break in = full power production.

RE: Satio 125
Hey all - I'm up at 500ft and thinking of running the Saito 125 on a Graupner G-Sonic 15x10 - dya think it will pull this prop on 20% nitro? Anyone experimented with 10" pitch on this motor?

I have an Enya 80-4C that if you try to start forward by hand will completely remove a fingernail before the fifth flip!!!

I usually have almost half a tank after 10 minutes on 15%, and flying pattern and sport. I'm using a 10 oz tank.

Very Impressive Efficiency!
What are your needle settings, sir?

RE: Satio 125
Mind if I take this one,blw? I'm guessing his LS is 1/16th to 1/8 turn rich from stumbling on transition, and his HS is 200-400rpm rich of peak.

RE: Satio 125
That's about where mine is tuned, as well. Of course my engine is still brand new, with only a few tanks through it. Perhaps it will become more efficient down the road. From what I've read, it will indeed.
