i have noticed that  some  wings  are  made in  real  3d  may be with  multi layer .  like in image  (1)

and  some  are made of just a single layer ..... image (2)


so....  which model   is  good   ??        

What  are  their (both models) advantages  and  Drawbacks  ??

seniors   please  clarify .... 

flat plate however curved will not match a truly cambered aerofoil, the question is what is your application. sometimes a simple thing like wing mount can completely alter your design, simplicity in making , curved flat plate anyday, cambered aerofoil can be tricky i making because if you falter even a little on the camber she can give you a hard time, if it is the first time , simple fat plate would do , dont bother to curve it at all, progress from there

getting  it  but   

a bit more explanation  would  satisfy me .......just want to know more ...


i am planning to build a Hot wire Foam cutter     ,,  can i use  a  1 mm nichrome  wire for that ??

i would really  appreciate  where  i could find 20mm epp sheets ??             and       templates  (paper printable)   for foam cutting.

Does it mean that even if the depron sheet is curved as the top edge of the clark-y  or a UC foil, it would still be considered a flat plate?

it wont be considered a flat plate. thats a flat cambered wing.

so.. which one gives us the most stable  flight ??   

or will there be any other effect  on the plane ??

I am  building  a  33"   Blu-Baby

and  the  wing   in the  plan  is  shown  below ..

I am thinking  of  building  a  wing  like  in the  second  picture...     with 3mm  foam  on top  and  bottom  

will there  be  any problem  for  that ??        what  shall  be  the  dihedral  angle or height ??


The  fuselage  of  the  body  has  a curve  for  the  wing    How  shall  the  wing  any  model fit  properly ?? can  it  bend into  good  shape ??

I think you can easily make that flat and mount your wing.
