 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...

 This is a small and simple Prandtl glider Span- 890mm, Root cord = 115mm, Tip Cord = 30mm, Sweep = 24 degree Will try out as a chuck, DLG and tow line It is a fairly simple contraction. The camber drops to 0 degree at 70% of span, and at the tip the camber is 0 and the washout is 9 degrees The topside.  The underside The fuselage is a just a stick to enable a small weight to be put way forward to get the CG right A side view. Notice the washout in the closer tip, the camber at the root  

Flying wing DLG  The details are : The airfoil is HS130 Span : 870 mm Root Cord : 196mm Tip Cord : 147 AUW : 125 gms The wing area is 149205 sq mm which translates to       wing loading of 2.74 oz/sq ft, and a wing cubic loading of 2.17,  The templates for hotwiring the wing.  The hotwired wing . Note the fuselage is a 4mm CF rod passing through the root. There is a 3mm balsa root which is in the center of the two wing halves and the CF fuselage rod also goes through it.  The faint line at 30% cord is where the a 3x1mm CF strip will be embedded to act as a spar A view of the wing tip. It gives you a perspective of the airfoil shape.... the foam tore of at the extreme tip trailing edge during handling The tail is made out of 3mm depron stuck onto the CF fuselage spine Also the 3x1mm CF strip which acts as a spar is visible The fuselage with a piece of scrap EPP foam attached tp the CF fuselage spine. This helps in holding the RX and the battery The...
