Hallo

Before couple of days, i bought the ys 110's and an APC 15 x10 . That's the prop for the time for break in and after but if i will find an APC15 x 8, it will must be better i thing. The Fuel that will use is 20/20. Break in will be at 4000 rpm's, 4 times for five minutes per time. I just need some informations for the tunning ( HS adgustment, regulator and LS adjustment). Flying at sea level. The engine will install at Fliton inspire 90 for pattern fly.

Do you have the manual for your engine? If not I will be more than happy to e-mail you a copy and then follow the break in and tuning instructions in the manual.

Hallo Petec

Yes, i have the manual. I believe that it will be helpfull for me, if i can read some posts from people who run and have experience about that engine. Thanks al lot for your eagerness to send me the manual.

A search of this forum will give a you a lot of info. The basics are in the manual however and once you get past the break in and general set up if you need to adjust it more just ask.

Here is one of my favorite pages on setting up a YS with the pressurized fuel system:

Thanks a lot Petec


That's my 4th Ys. I had the ys 63's and 120AC but i sold. For the moment i have an DZ 160 on a pattern. I know what i have to do about the pressurized system but i am wondering if the prop 15 x 10 is little heavy to run with fuel 20/20? By now, i search older posts about the engine but i did not fould a lo of details.

The prop should be OK on the 1.10S on 20% nitro, but what you really want to do is put a tach on the engine and make sure you are in the 8900-9500 RPM range. If the 15X10 is making the engine turn lower that 8900 RPM then a 15X8 might be in order.

I'd go with the 15x8. A 15x10 is probably going to load the motor down too much. For reference, the 110 will normally turn a 16x6 at around 9200.

15X10 works with 30%heli fuel. 15X8 for 20%.
