With an AUW of 11lb, what are people using for power on the 79" Yak? I am thinking either an ST2300 or OS160, with the 160 looking better for the more severe 3D stuff.


Thanks,

The 160 would be a sa-weet ride for that plane.

I'm running a new Mark 2.10 with a pipe. It spins a BME 20x8 8000 rpm, and it yanks the plane around with authority. Unlimited verticle at half throttle. It has great fuel economy on my 0% home-brew, because you're not working the engine too hard. Mine ended up at 12 lbs. even.

Duh. A YS140 Limited or DZ. Don't go with the ST2300. It is not the best for 3D flying and you will end up hating the plane because of it. Saito 220??!!

What about a moki 1.80?? Enough power?

YEah, the Moki would have plenty-o-power for that plane, not the most fuel eff. engine around but they do run on zero nitro...that help a lil. I'm running the 1.8 Moki on the 80" edge with no problems at all.

Well, I am a 2stroke fan and the YS engines are way too much money for my taste. The OS 160 would be my first choice, with the ST second. Why do you say the ST is no good for 3D? I know it has a funky rich spot at part throttle in stock form, but that is easily fixable and then it is a very engine. Nice and light, decent power and cheap. Can't really complain about that...
