Rahul's RC Aircraft and other designs

 This is a build log for a large plank flying wing. I named it "Pelican".. loosely based on the Pelican mentioned in nestofdragons The basic dimensions and calculations are as below..  The airfoil is phoenix The central section and each of the outer section are meter each. The outer sections have a dihedral.   It would has a central elevator and two outboard elevons/ailerons.. synchronized through TX mixing  The wings are hotwired out of EPS (closed cell polystyrene- thermocole) . It has a 1.25 inch top and bottom unidirectional carbon fiber cap spar and a 3 mm ply compression web across the whole wing. The whole wing is laminated one layer of 100 gsm fiber glass (unfortunately that was the lightest FG I could lay my hands on).. with the LE having a extra layer to form a Dbox The  wing is in 3 pieces (each of one meter), The outer panels are joined to the central portion by  rectangular aluminum bars and also locked with 4 x 3mm bolts   All t...

Pictures and build highlights of a SU 35 The plan printed on a A4 paper. The whole design was based around a 9"  space for prop (mid mounted). With that as the base, the conversion ratio was 1cm on plan was 5.88 cm actual. The total span was 95.1 cm or 37" and the length was 114.6 cm or 45" The above dimensions were drawn on a scrap newspaper and templates cut out or traced directly on 5mm foamboard.  Note the Increased dimensions of the wing and tailplane.  few pictures of the construction The front fuse was made out of 5mm foamboard sides with a eps turtledeck The nose was shaped  out of  eps foam. Below is picture of the elevator mount. The elevator was full moving elevator. It hinges on a 3.5mm CF rotating on a 2.5" al tube. The CF was wrapped around with clear tape to mage a snug fit The wing had a leading edge droop which was reinforced with two chordwise stakes in each wing Note the beveling of th...
