Arm.stl

Mount each arm to the X-Base using M3x8 mm socket head bolts. It is recommended to print the arms in pairs of 2 different colors, thus making it easier to distinguish the front from the back of the aircraft.

Mount each motor using four M3x8 mm socket head bolts. Thread the motor cables through the arm.

Arm-Cover.stl

Mount the arm cover using two M2x8 mm head screw bolts.

Mount the battery compartment to the X-Base using four M3x8 mm socket head bolts.

Mount the ESC pack to the X-Base using 3M double sided tape. Recommended ESCs are:

  • 4 x Flyduino KISS 24A Race Edition, soldered on Flyduino power distribution boad
  • 4-in-1 BLHeli_S, such as 35A Lumenier race ESC
  • 4-in-1 SimonK, such as 20A quattro Afro race ESC

Mount the RC receiver to the X-Base using 3M double sided tape.
