Something like the pic below...

With this design there's nothing you have to fab together and two full sized servos would be more than enough to do job.

Will you be offering basic model without gear options?

Regards
I will conside it the kit without the wing drive gear set . but now too early about this option , but not a big problem . Just one question , this full size servo i think power enough in the market high power servo . but in case one side servo not work when you are operate the servo moving , one wing open ,one wing close , what the happening ?But my design is the wing are same angle any time . if the wingrettract drive system not work , just to try land a detla wing models only . not much risk ! But if i use the two full size servo . i will keep the mechanic have join both side together and two servo linkage together , i think better and safty .

Good point...

Do you think it will increase cost much?

I agree. I have the balsa kit still in the the box - I am afraid it will take me a long time to have it flying.

Kin, I will wait for your Viggen version.

Thanks,

The F-20 start milling the master plug . it is one piece wing . Length 1.75m . for 100mm or 110mm fan if you have very good quality 90mm still ok . ep-retract gear pre- install .and gear door , scale air brake included . the one piece wing strong enough for mini turbine .

The Hawk will finish this month .the fuselage mold completed , let the first piece fuselage to fitting the first version balsa +foam cord wing . but tail wing still keep in full composite . just the main wing is balsa , the next version is full composite soon , but let the econ version first . the fuselage is sample and detail rivet work well in the surface, photo show is the pencil mark the rivet position for make the rivet !. fuselage photo post tomorrow .and see the fuselage how light we can ! And Looking for a test pilot for the new hawk !if interesting , pm me !

This F-20 add a little wing span longer 3 cm each side .but looking still good ! and a new F3B airfoil HN 3xx try to use in this models .speed should be ......exciting . It is one piece wing .so the structure are very simple and strength . the fuselage also one piece ,I cut the nose radar cone and the tail exhaust cone . let the parcel only 1.45m for easy delivery and lower shipping cost .But this F-20 is no econ version . only full composite version .cost is roughly 650-700 usd ! not yet sure now ! F-14 will after this models finish , i think in October!
