Vaibhav, the airfoil in your pic is a flat-bottom. I've come across many articles that say 'don't use true flat-bottom airfoils for anything'. What is your experience with these?
roopeshkrishna has very well shed light on the subject.
Personally i feel it is better than a flat-top wing. So it helps.
This link has got loads to say http://www.airfieldmodels.com/information_source/math_and_science_of_model_aircraft/rc_aircraft_design/plotting_airfoils/about_airfoils.htm
it also says so
Quote
Flat bottom airfoils are used for powered aircraft that are willing to make the compromise of having more drag in exchange for slow flight or high lift capabilities.  They do not penetrate the air well but can stay aloft at very low speeds.  I have built a handful of models having flat bottom airfoils that can hover right in front of me because the aircraft's minimum flight speed was below the wind speed.

@roopeshkrishna - It would be of great fun and inspiration to go through your build log. Go for it. Smiley

Vineet..its easy to shoot avideo of a boat is easy..but shooting a video of a car or an airplane is not easy to me, because i need two hands at time...hi..hi...here i do not have anymuch friends...but sure i will add a good video of the new Biplane, along with my other planes...within this time i also started to make a Dewoitine high wing fighter of WW1 and an Eindecker E.III ...both goes up to 44 inch wingspan...so i will post all related videos here..i hope it may inspire you some, as all you inspired me a lots....
