Rahul's RC Aircraft and other designs

This is a 1000 mm span aerobatic aircraft, in the lines of a pattern ship built during covid lockdown The wing is symmetrical , constant cord Span : 1000 mm Cord : 200 mm + 40mm aileron Airfoil :FX 77080 and 15% thickness The wing is hotwired, and the leading edge is fiberglassed with 100 gsm FG, upto 25%. This itself acts as a spar. Something like a D box.  The full length ailerons are 5mm depron covered with paper for stiffness The tail assembly, horizontal and vertical stabilizer, are constructed our of 5mm depron , with the leading edge (upto 25%) covered with paper Fuselage is box construction out of 5mm depron. The underside is fiber glassed  with 100 gsm FG The cowl was modified and the ailerons were trimmed to align with the wing tips She is beautiful .. both in looks as well as in flight characteristics.. hammerheads are perfect, rolls are controlled , it flies as if on rails..  

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 ...
