Power Master 20/20 fuel:
APC 16x6: 9300 ground peak
APC 16x4W: 9900 ground peak
Richard, what rpm does your YS 110 get with the Master Airscrew new K 16x6?

Still new YS, less than 1/2 a gallon.
Temp - hot
Humidity - pretty high
Fuel - Cool POwer 15%
Prop - APC 16x6
RPM=9,000 ground peak ... hope it improves when its properly run in.

I have found the Curtis Youngblood mix to be 200 rpm stronger than Cool Power Heli fuel. I think Youngblood mix has the new Klotz Heli Glow Synthetic. Just look at what each party (Wildcat, Curtis Youngblood, and Klotz) says, and these products are announced at about the same time... Hmmm
It made my YS 140 DZ 200 rpm stronger on APC 18x8W

Engine fairly new (less than 1 gallon fuel), Coolpower 30% heli, YS straight exhaust pipe (no muffler), 200' elevation, 80 degrees. I'm still dialing the engine in but it is running great!
APC 15x8: 9400 RPM
APC 13.8x10 4-blade: 9400 RPM
Yes, RPM is about the same for both props.
Flight performance with the 4-blade prop is surprising- much more power and speed than a Saito 100 with a 15x6 2-blade! Excellent for a warbird application.

It is the APC 4-blade prop design that some of the pattern guys use. I haven't seen them listed on the APC website but you can get them from Central Hobbies. There is very little selection in 4-blade props around this size.
The blade width and general shape is about the same as an 11" APC. Here are some links to pics that can be found in the multi-engine forum (P-61 build). Not my plane although I am building one like it.

By the way I took a walk around the Dayton air museum a few months ago and was amazed at how massive the "paddles" on the old 4-blade props were. So no they are not scale, but at least the general shape is close. Painted and detailed they ought to look pretty good on my plane.

Thanks for the info, Walt. I guess they look generally OK. I recently saw an small P-51 electric model with a four blade prop that looked really scale. Guess, it is easier for the Li-po crowd to achieve that look.........otherwise it's an old Byron purrpower set up in giant scale.

Update on my engine- yesterday after more flying and tuning (leaned the regulator a tad) I am now getting 9900 RPM peak on the APC 15x8. I richened the top end to bring it back to 9600 RPM for flying. I ordered a spinner for the 4-blade prop and will provide updated RPMs with the 4-blade when the spinner comes in.
I am new to YS's but already have three of them. It seems that fine regulator adjustments can have a significant impact on top-end RPM. On my 110 the regulator is now a little over 1/2 turn in from the original factory setting and it is running great!

I am spinning a APC 16x6 which would put the same load on the engine as a 15x8. My YS 1.10FZ regulator is also turned in 1/4-1/2 turn inward from the OEM setting and I am running mine around 9600 also. I can get more, but it would be going toward the lean side of the setting more. So, better safe than sorry. I started with a APC 16x4 spinning at 10,400 peaked but richen down to 9800.
My YS .91FZ spins a 15x6 very nicely also, but I can't remember the exact tach reading.

The key to these engines seems to be tuning. So far I've found that the factory regulator settings have worked OK, but finding the "sweet spot" on the regulator makes a big difference.
My 91AC will turn over 10,000 RPM with an APC 15x6 on 30% heli- almost not enough prop for it.
I'm selling all my Saitos.. [8D]

A related question- does anyone have experience with running the 110 inverted? I've yet to have a deadstick with my YS engines once they are dialed in, but they have all been mounted at 90 degrees. Once broken in and tuned I plan to put my 110's on a big twin mounted inverted. Reliability will be VERY important.
DTB- looking at your original post it looks like you have also gotten big gains in power by dialing in the regulator. I'm glad to hear its not just my imagination!

Okay ... after about a gallong my YS110 is really performing, here are the new figures:
YS110
Fuel: 30% Cool Power (heli)
Prop: APC 16x6
NO muffler
Peak: 10,300 RPM
YS110
Fuel: 30% Cool Power (heli)
Prop: APC 16x6
WITH muffler
Peak: 10,000 RPM
I run it at 9,750 RPM. I find that the engine performance is lousy if it is peaking at 9,300-9,500 on the ground. YS support forum recommends running at 10,000 RPM and I see some truth in it. My engine is running at only about 210F-220F after flying her semi hard, not too hard. Hence, the engine temp is very good.
Tomorrow I will be trying out the APC 17x6, shall give you all the figures.
Build - I am not buying any more Saitos ... YS may cost more but its worth every dime!!! I ordered a YS160 after this one. Saw a YS63 perform too ... sweet as heck. YS engines are the way to go. My TT120 2C gives about the same max RPM as the YS110!

Geez, that's a strong running 110 [sm=thumbup.gif] 9900 rpm peak on 15x8 and 30% fuel is respectable.

Has anyone tried Magnum 30% Heli 22%LV oil fuel in thier YS110, reason i am asking is I am planning on using a 1.10 in a 19% scale SU26 which I am working on, Coolpower 30% costs £26 - about US$48, Magnum 30 is £15

WOW, you guys are getting 10,000 RPMs from this engine? This is my first YS and I didn't think they would turn that high of an RPM.
I just barely got a tank of Power Master 20/20 through the YS before the storm came. Man am I impressed with this engine so far! I fueled it up, backed the high speed needle out 1 1/2 turns, opened the throttle to full and spun it with the starter, put the glow igniter on and bumped it with the starter (engine at 1/4 throttle) and it fired right up.
With the recommended starting point with the high speed needle 1 1/2 tun out it was spinning the APC 16X6 at 9000 RPM. I richened it up about two clicks and brought it down to 8800 RPM. I set the trim and it was idling reliably at 1800 RPM right out of the box! I ran the engine at mostly full throttle with the stock tank that came with the plane (Funtana 90) and it lasted quite a while I would guess over ten minutes. The transition and throttle response is absolutely unbelievable. You can wrap the throttle from idle fast to full throttle and it comes back to idle.

your little 110 have more power than 120 SF(I think)
try a 16x8 APC and tell me how it turn this prop
