Build: Octocopter

The Octocopter has 8 Engines mounted to 8 riggers forming a star. Compared to a quadrocopter or Hexacopter, it can carry more payload while being more heavyweight and having much higher power consumption.
For building an Octocopter, the engines need to be mounted as shown at the right.

• 1= Front Right (Clockwise)
• 2= Front Left (Counter-Clockwise)
• 3= Left Front (Clockwise)
• 4= Left Rear (Counter-Clockwise)
• 5= Rear Left (Clockwise)
• 6= Rear Right (Counter-Clockwise)
• 7= Right Rear (Clockwise)
• 8= Right Front (Counter-Clockwise)

The white arrow on the control board must point between Engne 1 and Engine2.

REQUIRED COMPONENTS

• Control Board (PCC or Celaeno)
• Octocopter-Frame
• 8 Brushless Engines
• 8 I²C-Brushless Controllers oder 8 standard Brushless Controllers plus PCC Extender board
• RC-Receiver
• Flight Battery

PROS AND CONS

• Carries more payload compared to Quadrocopters and Hexacopters
• Depending on payload, flights can be continued after failure of one engine (or 2 engines on opposite sides)
• Camera mounting is easier due to larger diameter
• Flight attitude can not easily be determined from greater distance (symmetrical layout)
• Construction is more challenging due to higher power consumption (cabling) and higher mechanical load due to its weight (not recommended for beginners)
• Higher costs compared to quadrocopters and hexacopters(additional engines, larger battery)
