Nice and clean build sir... Can you possibly share the dimensions with us all?
Regards

Very nice build....looking good...
Is it a straight wing, without V shape (dihedral or poly) ? I heard that if it is straight wing without V shape, it will not give good gliding characterstics (i mean, once u reduce the throttle, it starts coming down, it should glide atleast for 2 secs.). Because i have designed a same type of wing and faced little difficulties in gliding. it would be great help if you can post a flying video and complete wing design.
Thanks in advance.

@ kumardasai,,,,,,,, ya its straight wing,,,,,but the most interesting fact is tht its all-coro-wing no balsa or carbon fibre spar was used,,, still tough and xtrem light weight acheived,,,,whole new schemes where applied during wing construction,,,,,,coro flutes are horizontal across the wing span and not vertical as we see in normal coro wing design,,,,,wing have aerofoil ribbs running all over the span.

Straight wing or dihedral wing does not make any difference to the gliding. A wing with dihedral self corrects itself when turning. Meaning if you release the aileron or rudder, the plane becomes level. Whereas in a straight wing it does not level upon releasing aileron or rudder. It keeps turning. Also, a dihedral wing can be flown without ailerons however a straight wing needs ailerons in addition to rudder for effective turning. Hence trainers are usually given plenty of dihedral for easy flying.
