Rahul's RC Aircraft and other designs

This is a 1200mm plane built with a stick fuselage  The plan pic is below The wing has a Jedelsky airfoil, with the leading 30% cord made of 5mm balsa and the rest 70% cord made of 5mm depron. These two are spliced together and further stiffened with ribs. The ribs are also designed to induce a washout from root to tip.The planform design, specially near the tips also helps in reducing the camber near the tips.... All this is done to reduce tip stalling. It also has ailerons. There is a CF spar glued to the balsa. The Root rib is much thicker and reinforced. The dihedral is achieved but gluing together the root ribs .. they have quite some area in contact with the wing and between themselves.  Here is a pic of the same ..  The tailplane planform is also designed to handle high AoA without stalling. The tailplane is made of 10 x 5mm balsa frame and 5mm depron. This method adds a lot of stiffness without wt or requiring CF.  It has tape hinges.  The tail arm is lo...

 Here are the details of a SAL 1m plank wing glider The airfoil is PW1211. The wing is hotwired out of high density EPS. It has a 1mm CF rod epoxied to the underside , and a 5mm  wide CF tow lamination on the LE underside.. these act as spars. The TE has a 2 mm balsa 30mm wide, part of which is also the elevons, and balsa wing tips Fuselage is a 3 mm CF rod .. with some scrap balsa glued onto it to in front to act as the place to attach the RX and the battery.. the front part of the fuse is covered by a PET sleeve The wings are but joined with the 3mm CF rod sandwiched in between  and have two additional balsa joiners glued from top The whole wing and elevons are finished and coated with water based PU sealer mixed with light weight crack seal.  The rudder is glued onto the 3mm CF rod sticking out behind the TE It has two 4.5 gms servos controlling the elevons , and the 1s 350 mah bty directly plugs into the Rx. Dimensions Root Cord - 230mm (220 mm foam) Tip Cord - 1...
