Can any tell me if there is a Yak (that's available) that would fly well with a YS 1.40FZ?

No, but soon:

Woops

Do you think the 1.40 will be able to handle a 12.5 pound plane and still be able to 3D?
If it is, that kind opens up a few other options

it wil weight more than 12.5 lbs for sure

What about a QQ http://www.somenzini.com/grafico4.htm

Isn't the YS 1.40 close to a Saito 1.80 in power? The YS 1.70DZ should be sweet in this plane, but I think that the 1.40 will be plenty, but I don't know.

QQ designed his Yak for the YS 140 Sport. It's the engine he recommends for his Yak, swinging APC 18x6W.

I would love to get the QQ yak, if anyone knows where there's one for sale let me know.

I have a YS 1.20 AC that turns an APC 18x6W 8850RPM's on 30% heli fuel and it 3D's the crap out of a 10LB 80" profile at no more than half throttle for anything ( to keep the wings attached !) . I would think a 1.40FZ would be even stronger. I had a Saito 1.8 in a 12.5lb. Lanier Edge and even though my YS is stronger, it still had plenty of power to 3D the Edge. They designed the Great Planes Yak to fly 3D with an OS 1.60, which is a strong motor. I really want one of these Yaks !
