Hello!

Does anyone have any advice concerning engine choices for the Lanier 1/4 scale Extra 300s? I would like 3D capabilites and am considering the os 1.6fx or the moki 1.8. I am aware the 1.8 is a stronger engine, but its also heavier. Should I consider a slightly heavier engine for proper balance of the plane? I am still in the construction stage and am taking extra measures to lighten the airframe (foam turtledeck, hatch, etc.) ANY advice or input for this plane would GREATLY be appreciate!
