@ rahulroy31: Your build is very pretty. Just a few suggestions that I felt like while going through the pics. Please make sure everything is checked before flight.
1. Use prop saver band instead of the rubberband(correct me if I'm wrong) as I can see for fastening propeller on motor.
2. Ensure that all the wires are properly taped so that it does not get pulled and damage anything during landing.
3. Aileron servos should be very properly taped/glued.
