1.3m Twin-boom Pusher Wingspan - 1.3m (53") Length - 80cm (32") Airframe weight - 660g Flying weight (2200mAh LiPo) - 850g Motor - Turnigy 2822/14 1450kV (160W) 30A ESC Prop - 7 x 4.5" Ailerons Elevator TGY 9018MG servos x 3 ******************** The wing build is slightly different to my previous style, with cut out ailerons rather than full span. Wingspan is 1.3m or 53" compared to IBCrazy's 40" and 48" versions. I made a 200mm (8") x 20mm flat bottomed airfoil in two 700mm halves, then cut a wedge from each inner end to make the forward sweep when glued and taped together. The tips are about 45mm forward of the root. I also cut wedges off the wingtips so they were parallel. Naturally I cut them the wrong way first. I removed some of the forward former in the spar channel either side of the join so the Skyshark P4X spar had a wider bend curve.
