Speedy "Red Midi Swept Wing"

thingiverse

This is a forward swept wing that can be used with the fuselage of the "Speedy Red Midi Wing". The carbon rods pass all the way through, providing exceptional stability. You'll need one 8 mm tube and one 5mm tube, each 1000mm long. These rods are so stiff and fit in so tightly that you don't need to glue anything. This makes changing a part very easy, in case it is broken or you want it in another color. I haven't had a chance myself to maiden it yet. Recommended Print Settings Attention The wings are designed to print using 0.5 mm width, 0.3 mm height, 3 bottom and 3 top layers, but one perimeter only. If you print thinner walls, the perimeter of the upper side will not stick well enough to the perimeter of the inner stiffening construction. However, if you apply thicker walls, the perimeters may not come out continuously in one uninterrupted turn. To achieve a smooth surface on the upper side, the layers must build up as if you were printing in spiral vase mode. If you're unsatisfied with the results, try out 0.49 or 0.48 width in your slices settings. It depends on whether you use Cura, Slic3r, S3D or what else you have. I suggest experimenting with some tests before printing the whole thing. The second point is: if you print lesser layer heights, the inner stiffening construction will not connect well to the top and bottom layers, resulting in a gap between them. All wing parts should have a layer height of 0.3mm and a width of 0.5 mm. The specifications for each part are as follows: * Wing: 1 perimeter, 3 bottom layers, 3 top layers, hollow * Wing Servo: 3 bottom layers, 3 top layers, hollow * Elevon Inner: 7 (!) bottom layers, spiral vase mode * Elevon Outer: 3 bottom layers, spiral vase mode * Elevon Joint: no bottom layer, spiral vase mode Specifications Airfoil: AR2610-S80 modified Wing Span: 1000 mm Wing Chord: 200/128 mm Center of Gravity (CoG): 30 mm (stability measure: 12%) Overall Weight: 730 g Wing Weight (without components): 343 g Complete Wing Weight: 374 g Fuselage Weight Complete: 356 g Fin Weight: 12 g Wing Area: 16.6 dm² Wing Loading: 44 g/dm² Longitudinal Stability (Thies) STFs: Motor: Propdrive 28-36 1000KV Static Thrust: 950 g (3S Lipo) Battery: Turnigy 1200 mAh 3S 40~50C Lipo Motor Camber: tilted -4 degrees Side Pull: none Propeller: Aeronaut CAM Aeronaut Carbon Classic 10 x 6"
