On 10% Nitro Sig fuel, OS #F plug, I get the following:
APC 15x6 @ 9500
Zinger Pro 15x6 @ 9200
Anybody has the tach number for Zinger 16x5 prop?

Looks like I gotta use 15% nitro. Hopefully after running a few gallons, its power will reach 9800 on APC 15x6

mecam,
How was the throttle response with the 16x4W on Saito 100? Was it pretty laggy? I tried the 16x4W on Saito when it was fairly new, running on 10% nitro fuel. The spool up was really slow, and would not hold a reliable idle. Would 20% nitro make substantial difference?

In reference to 30% nitro heli fuel for the Saito 100, this is ok. Morgan Cool Power Heli 30% nitro/ 22% synth oil. Check out Horizon Hobbies web site about the Saito engines, they even recommend it, as long as you have good oil %. Personally, I use 20/20, a buddy uses 30% in his Saito 91, and it runs very good!
This is a direct quote from Horizon's web site:
"Notice that we achieved significant increases in performance (300 to 400 rpm) when using 30% Cool Power helicopter fuel in the Saito but saw minimal increases in the O.S. with the high nitro fuel. Our staff commonly uses 30% heli fuel in Saito engines, as it not only gives better top-end performance but it runs smoother, gives a better transition, and runs cooler."
Hope this helps,

Sure 30% will cost ya a bit more $$, but if you want that little extra in power, it's gonna cost ya a little extra in fuel...... pirate:

I have found that all my Saitos (have 5, including a twin) just seem to run and idle a little better and smoother with the 30% fuel. I am lucky though, I mix my own and get nitro and alcohol for free.

RE: Saito 100 Tach Readings: Please Post
I just ran my Saito 100 w/ 30% nitro Cool Power Heli fuel. I have the following:
APC 15x6 @ 9900 rpm. On my force gauge, it pulled 12.5 lb of static thrust.

Saito 100
YS 20/20
Zinger 14-8 9500 rich
APC 14-8 9800 rich
Graupner 13.5-7 10,000 rich
Zinger Pro 15x6 9200 rich
APC 15x6N 9400 rich
Graupner 14-7 9800 rich
Glug OS-F
Model
Kangke USA Cap 232 Sport 8.5 lbs
Good vertical, can hang on the prop with 14-8 and accelerate from hover straight up
15-6 Zinger Pro had a little detonation on top end. Good downwind braking, seems to run a little too much RPM for what I like to do, 14-8 is better for me. Also I would run Graupners full time if I could find one in the pitch I want.
