11580 rpm with an 11x8 propeller, which corresponds to a power output of approximately 1000 watts. That is as much power as a 2-stroke methanol engine with this displacement provides, very impressive.
Despite the odd difficulty with tuning here and there (I suspect the fuel as you rightly mentioned) I'd say that's quite a successful run. Most amazing is the snap-quick throttle response, excellent engine, keep 'em coming David. Regards Harry
RUns fine, and is a real-world situation. Idle is quite high but what top-end rpm for a four-stroke. That was quite surprising. Thank you for the video.
Hi David, how would this engine perform with a slightly bigger 12x8 prop ? my Saito FA62B runs with Coolpower 15% heli fuel 11870 rpm with a APC 11x8, switched to a 12x8 and still 10580 rpm but way better and smoother running ... eeh "Flying" :D i really appreciate your video's and i'm glad you still share your hobby with us
Only one is required on this per the instruction manual. Should only be one on yours too according to this manual. drive.google.com/drive/folders/1URXkXJelMdUuQOT0Ot06oKOGwDz_wTK5
Of course it runs pretty well on 10% nitro, it's a little more finicky to dial in but it works really good, well it's a YS!
Such a cool little piece of art! That rpm is on 2 stroke level.
Sorry, but that "2" identifies a 2 blade prop, NOT a 2 stroke engine...
@@bilbag911 I mean that 4 stroke revs as high as a 2 stroke
I have a ys63, unfortunately haven't run it as much as I would like either. Once that tune is dialed, the throttle response and power is👌

What a firey little beast!

Sounds mighty fine!
VIDEO INTERESSANTE GRAZIE
FZ 63 are a mighty little engine !
Once you have a chance to play around with it, you'll be surprised how bigger Prop they'll pull !
Nice buying

Define perform. I am running props recommended by YS.
How many check valves does that one use, I've got to have 2 with my ys 120 !
