Rahul's RC Aircraft and other designs

 A slightly different 3D plane designed and made by me. Span is 900mm The wings are low AR and highly tapered. It has a deep fuselage, akin to a pattern flyer. The LE of the ailerons are also tapered. Additional vertical side was added via wingtip plates and a dorsal fin. This gives the ac fantastic tracking an handling. All surfaces are made out of 9mm epp sheets, which were hotwired out of a EPP block.  It has a few CF 3x1 mm strips embedded for strength and stiffness. Additional stiffness is comes from fishing line rigging across the fuselage, wings and tail surfaces. This gives the aircraft very good stiffness without adding weight and is very strong (the fishing line is kevlar).  Electronics : 2212 1400kv motor, 9x5 prop, 30A esc, 4 x 9gm servos. Flies witha 1300/1000mah bty.. AUW 500gms.   A beautiful looking aircraft, which also flies amazingly. Even other flyers vouch that it flies better than many brought out 3D kits. Here is the plan

 This is a 1 meter pattern aircraft ... not a typical shock flyer. Dimensions (mm) The whole aircraft is made out of EPP The wings was hot wired out of EPP.. RAE100, a medium thickness airfoil was chosen over a thick airfoil to reduce drag. It has two 3X1mm CF strips glued on the top and bottom surface at 35% cord, and one outrigger to the tip TE. The ailerons are 6mm depron. The horizontal and vertical surfaces were 10mm flat plate EPP with the LE rounded. The TE was left as it is to have requisite strength. 3X1mm CF strips are glued along the hinge line for strength The fuselage has a EPP 50mmX40mm central spine which has 3 CF rods (3mm) glued along the length for torsional and longitudinal stiffness. The wing and the horizontal and vertical surface is mated to this central spine. The overall outline of the fuselage is a 10mm EPP which is also glued on the central spine. The battery is pushed in a through slot in the spine (between the CF rods). The slot is cut as forward as pos...

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...
