Ikarus is a thrust vectored flying ducted fan. This page has the design files for the project.
See an overview of Ikarus in this video:
This is an advanced RC project, I don’t recommend this for beginners! These are not plans, just a list of things you’ll need to get and 3D print, then figure out how to assemble into Ikarus. There will be holes that need to be drilled, things that need to be shaved down on 3D prints, etc.
- QX-Motor 90mm EDF + 80A ESC (Aliexpress)
- KINGKONG Micro CC3D Flight Controller (Hobbyking)
- 4x Corona DS-918MP Digital Servo 1.8kg / 0.06sec / 9g
- Radio of your choice (Minimum 4 channel, 6 recommended) (I use FrSky 2.4GHz ACCST TARANIS X9D PLUS Digital Telemetry Radio System (Mode 2) plus FrSky D8R-XP 2.4Ghz Receiver (w/telemetry & CPPM))
- Batteries 2 or 4 of 3S LiPo, around 2Ah (I used 4 of Turnigy 2200mAh 3S 25C Lipo, but 2 would likely be better)
- 2mm rod for vane pivots
- ~0.8mm rod for control linkages
- Connectors, wire, zap straps, tape, etc.
Download the 3D models below and print 1 of Nozzle, 2 of Rudder Left and Rudder Right, and 4 of Leg. Raft and supports are required for all parts.
Assemble the craft, refer to the video for how things go together.
CC3D output servo/motor channel mapping (Looking from top of craft, receiver at bottom)
- Top Right servo
- Top Left Servo
- Bottom Left Servo
- Bottom Right Servo
- EDF ESC throttle
CC3D Input Channel Mapping
Program the flight controller with the following custom firmware
CC3D Firmware with gyroscopic compensation feedforward
Load the settings file
Check Channel 5 configuration, must be set to minimum (mode 1) for normal flight. This channel selects control mode (min = attitude control (normal), middle = rate control (Acro), full = open loop (Directly controls vanes/throttle, no stabilization)
- The “front” of the craft is the ESC side, the receiver side faces you.
- For a clean takeoff, slowly ramp up the throttle to about 30-40%, then quickly raise to about 50-75% , then reduce as appropriate to maintain altitude once in the air. Ramping up too slowly will result in the craft tipping over. The thrust vectoring bleeds off a lot of power as the craft initially stabilizes after leaving the ground, so an extra burst of power is required until the craft is stable in the air.
- Roll/pitch is much slower than a normal quadcoper, be prepared for this
- Plan to fall over upon landing unless you come down perfectly straight or make the landing legs wider.
