The things 1 1/8 times the 57 in ' Typical .46 ' one I did . This gives 125 % the Area, About 800 Sq. in here .
The Stalker 76 ( or 66 ) is Fitted . as it fitted .
The 57 in one had ' Canards ' The Exhaust Stacks were about 3/4 wide x 3 long , Ea Side of the nose .
Initially had a ' nose down left ' trim . Glareing along from Fwd. noted that one side was angled off C/L .
Fitting it straight got the trim level and neutral .
Idea was to see , if like a Kfir C2 , they were a " Lift Improving " device .
As the lateral trim is descerable if theyre angled , thyre definately ' aerodynamic'; up there . Which is a good start .
Other deviation from knomal is the Center Section SET UP .
The Trailing Edge and FLAPS are one line , Center to Tip .
Whereas;
The Center Section SPARS and LEADING EDGE are FLAT ( though Ive got a 1 m.m. drop to break on top surface ,so as it dosnt APPEAR sagged .)
Therefore Fwd of the Spars Symetrical with about 6 mm drop on the centerline of the T.E. GIVING a Assymetric Airfoil inboard .
The benifit of this Appears to be The Flaps are More Efficent at low movement INVERTED due to the deflection being IN LINE with
the Shallower Slope on the underside sheeting of the centersection , I presume .
As it Floats Through the downhill to intersection , inverted from the upper loop of the Vertical eight ;
giving you all the time in the world to ' hit the cut ' on the reversal to the top of the Inside .
Thats my theroy , in Hindsight .
Though theres a touch of wash out ( 2 mm ) Ea. Tip : which is ' Wash In ' INVERTED ! .
you can detect this with the
' rolly feel ' ( balance point / instant resonce ) inverted .
This came about as Id forced the Sheet Fwd. and Aft. on the center ribs to make a STRIGHT LINE after Id Secured the T E to the outer Ribs .
Think about it , theres a shift in the l.e. of the T.E. at the Diheadral Break . It shifts the T.E. Sheet Top aft a few m.m.
and the undersheet back a few mil.
Forcing thinto line sets the tips up about 2 m.m. at the trailing edge .
As it was Even / Symetrical ( side to side ) I thought it Easier to leave well alone and ' see what happens ' .
THIS ONE will get 1 m.m. Wash Out and carefully Trimmed & Cut Trailing Edge Sheets in there !
Back to The Grindsrtone . It still unused in its boox on the shelf .
