RE: YS CLUB

Thanks for all the replies guys. I've been a running 63 with a 14x4W prop on a 3D profile for a year now and it has ridicules power. It's really rare that I go over 3/4 throttle, I'm not really a...

RE: YS CLUB

I got ahold of YS and they helped me determine my engine is an SF.

So now that I know that my motor is the 120SF, what type of 3D performance should I expect from it on a 10.5-11 pound Yak?

RE: YS CLUB

Thanks for the info.
How do I know which model of 120 I have? I don't have the box or paperwork anymore for my engine, it just says f120 on the side of the crankcase.

RE: YS CLUB

israelg48, don't attach a deflector straight to the header, it will melt and fall off within the first flight.
I've had very good luck just removing the baffle from inside the muffler. It gives a...

RE: YS CLUB

RE: YS CLUB

I got my first 3 flights on my F90 and YS 110 today. I have to say that so far I'm very impressed with both the plane and the engine. I do have one question about the engine though, I notice that...

RE: YS CLUB

Do you have both inlet and exit holes in the cowl for the cooling air? The exit hole needs to be at least as large or larger (I've been told up to 2 times as big) as the inlet hole.

RE: YS CLUB

I just got a 1.40FZ and I'm trying to decide on a plane to put the engine. What weight 3D plane will this engine handle well? It doesn't have to be a rocket but I would like it to have good power for...

RE: YS CLUB

I recently had the chance to get a NIB 91AC, I'm wondering if this would be enough engine for the H9 Showtime?
Also, is there anything I should know about this engine?

RE: YS CLUB

I just picked up a 1.40dz and noticed that it doesn't come with a muffler. Will I hurt the engine if I run it without a muffler?
