Twerk - RC Fun Flyer with two motors

cults3d

Edit - 04.09.2019: The model flies ok, but is quite unstable in roll, and doesn't have the best stall tendencies. Future development might include wingtip fences instead of the swept back wings. Edit - 05.02.2019: Replaced the old 6x4 props with smaller 5x3 props because they were too big for the drone motors. Here is the maiden video:https://youtu.be/crs-MnMg0uY It is expected to be a relatively fast model capable of vertical take off and wild maneuvers using individual throttle control. The bumps under the wing are 35 mm from the leading edge and is expected to be a good starting point for balance. Use nylon filament or some other 1,6-2mm rod for the aileron hinge points. Use CA hinges for the tail control surfaces. The printable clevises can be glued to the ends of 1,5-2mm carbon rods, and the shackles are for the aileron threaded control arms. Wingspan: 720 mm Length: 570 mm (with Nose01) Weight: 600-750 g Expected CG range: 30-40 mm Expected control surface deflection: <10mm Materials needed: -CA hinge material. -Countersunk M3x8 and M3x25 screws for wing attachment to fuselage, and wing attachment to carbon wing tube. -M3x12 mm grub screws for attaching the propellers to the motor shaft. -6 mmx350 mm carbon tube for the wing attachment. -1,5 mm carbon or steel pushrods for the controls. -2 mm and 4 mm bamboo, wood or carbon rod for the alignment of parts and the hatch latch mechanism. -4 mm spring for the hatch latch mechanism. -5 typical 6-9 g servos can be used. -2205 mm 2600kv drone motors are used in the prototype but the motor plates are drilled for a large variety of motors.

Heavier battery is needed to balance if the model is printed heavy: https://www.banggood.com/custlink/3GvDpDADN6
