Behold: The Jellyfish video manual!

I have also created an article on Rotorbuilds which can be considered a written manual. Click here!



Summary of the most important remarks


3D printing (1:40):

  1. Print "regular arm" 3 times, all other parts once.
  2. Print everything along the horizontal axis of the print bed.
  3. Basic filaments (ABS, PLA, PETG) tested and approved. Ofcourse, durability and weight depends on the chosen filament. Flexible filaments (TPU) not recommended.
  4. 0.4mm nozzle or less, 0.2mm layer height or less.
  5. No infill, some top and bottom layers.
  6. No support.

Building (5:40):

  1. USB arm => USB side of the frame. Preferably rear left or rear right (video example: rear left)
  2. Very important! For a props-out configuration in pushprop setup: front left = CCW rotation as seen from the top of the frame. => CW motor with CCW propeller mounted top first on motor shaft because motor is installed upside down! Same goes for the rear right of the frame.
  3. Very important! For a props-out configuration in pushprop setup: front right = CW rotation as seen from the top of the frame. => CCW motor with CW propeller mounted top first on motor shaft because motor is installed upside down! Same goes for the rear left of the frame.
  4. Only apply a drop of glue on the bottom of the shroud where the connections with the arms and camera mount are. Glue on the motor block connections is unnecessary and makes replacing motors more fiddly.

Betaflight setup (20:20):

  1. Board and sensor alignment needs a 45° (USB rear left) or -45° (USB rear right) adjustment on the yaw axis. This goes for the Crazybee F3 flight controller and should be applicable to all other boards that have the USB port in the same location. In any case, make sure the board has its orientation correct!
  2. Very important! For a CCW rotation as seen from the top of the frame. => CW motor with CCW propeller mounted top first on motor shaft because motor is installed upside down!
  3. Very important! For a CW rotation as seen from the top of the frame. => CCW motor with CW propeller mounted top first on motor shaft because motor is installed upside down!
  4. Read 2 and 3 again, it's just too important. 1 mistake here = no liftoff! When done, continue to 5
  5. Read 4
