A Safety Parachute For A Quadcopter

Posted August 21, 2015

Mayday is a standalone machine learning device that detects when your quadcopter, tricopter, octocopter, or hexacopter is crashing and deploys a parachute. You can program it to do a wide range of servo release motions to protect against a crash. A two cable interface and mounting makes it easy to install.


The Mayday can be used all by itself without any connections to a flight controller. Simply connect the parachute release servo to its board with a small battery. Connecting the Mayday to your flight controller adds an extra level of control when flying.


Tech Specs:

Plastic Case: the shell is a special lightweight polymer. The acrylic top plate is made from a special UV blocking blend called OP3 Acrylite which is stronger and more scratch resistant than glass.

Weight: Mayday will weigh around 14.1g

Size: Length 3 cm  Width 3 cm, height will be between 1 cm to 1.2 cm


  • Li-Po battery range: 1S, 2S, 3S, 4S.
  • Voltage range: 3v – 17v.
  • You can easily use it with any RX channel capable of driving a servo.


  • Onboard it has a high-resolution Altimeter to detect relative altitude,
  • a 3-axis Gyroscope for rotation speed,
  • 3-axis Accelerometer to detect angle and gravity,
  • a 3-axis Magnetometer to for angle,
  • heading relative to magnetic north.


The project campaign is fully funded on the Kickstarter and reached its funding goal of $12.000, the early bird pricing are gone, but you can still get it for $75, an estimated delivery is on Nov of 2015.
