This article is about scratch building a design that looks like an airplane but with a missing wing. A picture of it is shown below.
This monocopter flies by spinning around. Its wing acts like a blade of a helicopter. A video and an image of its flight is shown below.
I cut a rectangle out from a Dollar Tree foam board. The dimension of the rectangle is 8 inches by 30 inches. To form the wing, I cut and fold the rectangle 2 inches away from the leading edge.
The motor is attached to a motor mount cut from plywood. I insert two carbon fibre rods through the motor mount. I further attach more plywood on the carbon fibre rods so that I can glue the wing on them and prevent the other end of the rods from getting loose.
Aluminum rods(7mm diameter) are used to form the legs of the monocopter. This can prevent the blades from touching the ground. Foam is used to wrap around the electronics and batteries to prevent damages.
The whole monocopter including batteries is 8.5 oz.
I get the motor and propellers from Amazon. Motor used is E-flite Park 370 Brushless Outrunner Motor 1360Kv. Propeller is RAYCorp® 1045 10x4.5 Propeller.
Electronics includes a RC receiver, 2S LiPo battery and an ESC speed controller. Since my ESC does not provide power, I add an additional small battery to power the RC receiver.
I start with half throttle to spin the monocopter on the ground. Then, I slowly increase the throttle until the monocopter is almost airborne. At that point, I quickly increase to full throttle to keep it in the air.
