The chassis of the Quark is a single print and features ample room for a 30x30 FC / ESC / VTX stack

Routing wires is also breeze, especially thanks to the hard mounted XT60

Multiple nose and tail options are included, as well as blanks

Printing:

  • Print using anything but PLA. Temp resistance and strength are of utmost importance here, so we recommend PETG, ASA, PC, CFPC or other high-temp resistance materials

  • Minimum print bed size is 220x220mm (z axis should not matter)

  • Print with 2 walls and 10% cubic subdivision infill. Feel free to experiment with different infills and percentages

Assembly:

  • Install M3 heated inserts (height < 6mm) on any of the larger (4.5mm) holes, including inside the cavity where the stack should be mounted

  • Route the motor wires through the slot on the top of the chassis

  • Use the slits on top of the chassis or on the lid to mount your battery using straps (either top-mount or bottom-mount)

  • Route your camera wires through the slit under where the nose screws on

  • Route your GPS and XT60 wires through the slit under where the tail screws on

  • Use a mmcx to SMA extension to mount your VTX antenna on the tail if desired

  • Feel free to use a dremel (or modify in CAD) to cut a hole in the side of the chassis for USB access to the FC

  • Be sure to use thread locker when installing the motors on to the arms

Hardware:

  • We recommend using a 30x30 stack with the ESC / FC / VTX built in (such as the Holybro Kakute F7 or SpeedyBee F7 V3)

  • Motors: 2207 1850kv or similar (many other options, please experiment)

  • Propellers: 5x4.5x3 tri-blade props (many other options, please experiment)

  • Both analog and digital FPV systems can be mounted to the Quark.

    • Analog camera: Caddx Ratel or similiar

    • Analog VTX: 30x30 RushTank or similar

    • Digital camera and VTX: DJI or Walksnail

  • We recommend using the Radiomaster RP3 ELRS 2.4ghz receiver (as shown in the above images) however of course this is open to individual choice

  • Battery options can range from Lipo to Li-Ion

    • For maximum fun, we recommend a 1500-2000mah 4S Lipo

    • For 30min+ flight times, we recommend a 4S1P 21700 Molicel P45B (4500mah)

    • For maximum endurance, we recommend a 4S2P 21700 Samsung 50E (10,000mah)

Software:

  • We strongly recommend using ArduCopter if you desire excellent autonomy and GPS reliant navigation

  • Betaflight is also a good option for freestyling and the gold standard when it comes to acro performance

  • Download the Ardupilot params here (keep in mind not all parameters will apply to your build such as flight modes and serial outputs)

  • Download example flight log here (flown in a FRIA)

  • We hope to improve the parameters and provide Betaflight ones in the future as well!
