Default What engine for Nitro Models Yak 74"

I thought I was getting a 69" with less than 10lb build but see that this plane is larger at 74". It might be a 73" as I didn't measure that carefully but some have commented that it does not build up at less than 10 lbs as suggested in the adds and needs larger than a 1.2 engine. I'm not looking to 3D the plane but would like unlimited or nearly so vertical though I don't want to be over powered or for the plane to carry more weight than needed for reasonably good aerobatic performance.

I'm only interested in a gasser.

All suggestions are welcome and appreciated... thanks

I run a Brillelli 46 in my extreme flight 74" and its over powered and weighs just about 11 1/2 pounds.

My 10 pound, 70" Cermark flys very well on an MLD28

Quique makes a 73" Yak that they claim weighs 11-12.5lbs. He has a video of it flying with a 26cc gasser, and while he's not thrilled with the vertical performance, it's enough to fly 3D and pull out of a hover.

Here's a link to the video: [link=http://www.qqaircraft.com/default.asp?s_nav=1&s_page=evo73_hi]click me, click me![/link]
