sir will provide my ornithopter details.. its completely scratch build(incomplete)
will update image lateron
motor: 5000kv outrunner
30A esc
25" length
50" wingspan
lipo: 2s(500-900 mah)
2 metal gear servo(13gm)

gear system is handmade using micro bearings and 3mm shaft.. through my calculation in no load it can produce almost 8fps flap rate when 2s lipo is used..

wings are made of polythene film and carbon rod(3mm main spar and 2.5mm support rods)

the auw will come around 400 grams min(in ma calculations)
please provide me the changes needed and guide me...

Look attached file.
It is necessary carbon rods to put on wing membrane by the material of a membrane using double-stick tape.
