Figures... I just bought a new .91SRX last week. Oh well, I got a screaming deal on the .91 and I really doubt that I'm going to be unhappy with it based on what I've read.

What do you need video for? I'll have it at the funfly this weekend.

I do want to see Leon flying it, however.

Mine is at home :thumb up: unfortunately I am not at home for 2 weeks

The more I don't have airframe to put the engine in re- but it can be solve quickly

My question is : I only use Cosmo Black special 30%. Will this fuel fit directly in the 120SRX or do I need to uncompress with another gasket ?
Normaly on the manual I saw that we can use up to 30% fuel but...

Thanks,
Rms

I ran two full tanks thru my new 120 SRX today. Even running blubbering rich, there is a marked decrease in vibrations compared to my 120 SR. Unfortunately, my 700N clutch exploded on the third flight, so I'll have to finish tuning/wringing it out tomorrow. Stay tuned...

The vibration monitoring (VBar Silverline 5.3.4 Pro) is the same as by the YS91SRS-RR (use it before to change to the YS120SRX) . The YS120SRX runs smooth at 1400, 1700 and 1900rpm.

Can anyone comment on the HP power output of the 120 SRX?


Mine is on the way, got mine from ExperienceRC, I also ordered the Tim "High Needle" Jones 120SR pipe.

The power output is the same, if not a bit better than the 120 SR. I can't speak to reliability or tuneability yet, because I don't have enough tanks of fuel through it...
