Thanks MikeG,
I want to break mine in, but I am not sure how many tanks to to fly in normal mode of about 1600hs? I am using RotorRage 15%. I also have 30%, but the manual makes no mention of the use of anything higher than 15-20% for break OR normal flights. YS did not give me any extra head gaskets for the SRX. |

A couple hovering flights to get things started. On the 3rd flight, fly around a little and begin adjusting the needles. 4th flight start doing light 3D and continued tuning. 5th flight on, fly the crap out of it. Also, I would run 15% in the 120, it just runs real good on it.

In my opinion has the YS120SRX the max. power/torque between 14.285 and 15.188 RPM with a gear ratio of 8.21 (1740 and 1850 rotor rpm (Raptor G4.1/Raptor N820)).

What about parts for the SRX, are some of the parts from the SR interchangeable, like the piston, conrod, head gasket, rear bearing?

I think the bearings are the same for OS .91, 105, YS .91, 120.
I think the pistons are different between the SR and SRX. I bet the head gasket is the same. No idea about the rest. |

New YS 120SRX
Couple of quick flights on the YS120SRX, bit rusty on the sticks but really happy with the engine, will drop a shim out as well (running two currently), tad lean on mid/idle, easy fixed though

Hi Brendan78,
nice flight! IMO has the YS120SRX much more power with a gear ratio 8.21.

I spoke with Hatori USA, but not much help, not much was clear really. I asked how many pipes were made for the YS 120, replied "only one" really!
Ok what about the Tim Jones pipe? "well that I think was custom for the YS 120" what about a pipe for the 120SRX? "We released a pipe for engine 3 weeks ago" Which one is that? "the SB-23FH" ??? I have the SB-23FH-3D-3 |

New YS 120SRX
If you carefully read both the srx and sr manuals, you can see that the difference is on the crankshaft. So I figure that the pipes made for the sr work with the srx...
I run it with the hatori 120-3d from RC japan... Rms Sent from my iPhone using Tapatalk |
