    Yak-55



    Yak-55

    Good flying 3D profile airplane -- at a GREAT price!
    32" wingspan, 29" long, 208 sq. in. wing area, 8 oz. flying weight. 5-1/2 oz. per sq. ft. wing loading. Lightweight pre-printed foam construction, the parts are pre-notched for accurate and strong assembly. Wing stiffened with 3mm carbon rod. Carbon rod material for elevator and rudder pushrods included. Assembly takes only an hour or two using foam friendly CA. Light enough for indoor flying but still has the strength and stability necessary for outdoor flying. Fully 3D capable with the power system that we recommend. Controls are Aileron, Elevator, Rudder, and Throttle

    where should the CG be on the YAK-55. The instructions say at the spar location. I moved it back about 3/4", and now it flys very well.

    I am seeing that from on the spar to about 3/4 behind is good.
    Depends on how the pilot likes to fly.
    Kind of a matter of taste for the "COOK".

    I was asked this question today:
    What is the Yak-55 made of?
    It is made out of Depron which is a rigid surface high density foam.
