lgodin-RCU,

What engine are you using in your small Yak? Any idea of the all up weight less fuel and the wingloading?

Have been toying with idea of installing MVVS 1.6 gasser in mine although EF says that the YS 110 is perfect for this model. I don't do 3D but I would like some decent vertical and I also don't want a high wingloading an I am afraid thats what would happen with the MVVS. Ef recomend engines in the 20 - 30 oz range and the MVVS before exhaust is 38 oz. May not be an issue but I don't want to fork over the bucks on the MVVS if it isn't going to be right. Also consider Enya 155R FS or Saito 150 FS.

Hmmm tough choices to make.
