Multiplex Funracer FPV build

Got myself nice new Funracer from Multiplex. Build was semi-easy as plane comes almost ready. It was a little pain to install everything FPV related as fuselage is already glued together. I had to shorten the canopy to fit DJI Air Unit. But with a little 3D printing it fits there perfectly. Camera is on servo with support bearing. Hope this will work well.

There is small battery to keep plane light. Battery is exactly in CG even after adding all FPV related stuff. I might experiment with different batteries later. Not flown yet.

Specifications:

  • Funracer by Multiplex
  • Stock motor
  • Stock ESC
  • Stock servos
  • Stock propeller
  • 3S/2200mAh Lipo
  • Matek F405-WING autopilot with INAV
  • Matek GPS
  • DJI Digital FPV system
  • My own version of  OpenLRS with integrated balun and dipole antenna
  • All Up Weight = 1090g (including battery)

    Hello Kolin’s,
    Thank you for sharing your experience and work with everyone.
    I have bought a Funracer and I have thought about mounting a Matek with Inav. Searching the internet I have found your site and I have seen that you have done it before and, according to your video, with good results.
    I would like you to tell me how it has worked for you and what is your experience of this combination.
    I would also like to know what Matek configuration you have mounted and if you could send me your configuration to mount it on my board.

    Thanks in advance and I await your reply.

    Greetings, Darío

    Hola Kolins, te escribí un comentario hace semanas sobre el Funracer de multiplex, pero no he tenido respuesta.

    Me gustaría saber si estás contento con INAV en este avión. Yo tengo el mismo avión y una matek f405 wings. Ahora estoy pensando si instalar INAV o Ardupilot.

    Gracias por tu ayuda y por compartir.

      This plane is a bitch to fly. INAV can fly it. So far it is sitting on the shelf. I plan to try Ardupilot in it. Some day….
