Rahul's RC Aircraft and other designs

 This is a 1 m combat wing. It is hot wired out of EPS foam (thermocole.. high density).  Dimensions Airfoil is TL56, thickned to 120% It has one 1x5 mm CF strip embedded vertically in the underside to act as a spar.  The two wing halfs are butt joined and the motor mount is also a cross beam joining the two halfs  The elevons are 3 mm balsa covered with monokote The end plates made out of coro , and the flutes are vertically aligned A strong fishing line has been glued along the whole LE to prevent dings ..  The whole aircraft is lightly misted with 3M77 spray and then covered with tape (colored tape).  Servos are mounted on slots on slots cut on the top surface, keeping in mind bind free linkage geometry and as close to the RC as possible.  Electronics (electronics , powertrain, battery choices are greatly governed by what is available with me.. sometimes may not be optimum) Power train - 2206 2400kv Quad motor, 40A ESC,  driving a 5x5 tri blade...

A pivoting wing design in the lines of Mignet's Flying Flea Front wing : Span : 755 mm Cord : 155 mm Airfoil : NACA 23112 Dihedral Rear wing Span : 510 Cord : 155 mm Airfoil : NACA 23112 No Dihedral Motor : 2204, 1400kv, 3s 1500 bty, 30A ESC, 7x4.8 prop, 2x 9gm servos. All these are reused components , and specially the motor/bty/esc combination could have been much smaller and lighter Horizontal separation of wings 15 mm, Vertical Separation of wings 85 mm Wanted to keep the construction  simple Both the wings have the same cord and airfoil. This makes construction easy in terms of hotwire airfoil template / ribs> The wings are hotwired out of EPS, and the leading and training edge have been laminated. There is a 3/4 span 3 mm CF road in the front wing.  Two thin Aluminium "L" section have been epoxied at 20% of the cord, on the bottom surface of the front wing. The lower prong of the "L" have holes through which a bolt attaches it to ...
